Uniquely Small Protective Carbohydrate Epitope May Yield a Conjugate Vaccine for Candida albicans

The cell wall phosphomannan of C. albicans is a promising target for the induction of immunity by development of a conjugate vaccine. It contains a unique antigen, a (31,2-mannan that affords active protection to mice following immunization and subsequent challenge with live organisms. Disaccharide and trisaccharide fragments of the (31,2-mannan antigen optimally inhibit two murine monoclonal antibodies that confer protection in a mouse model of candidiasis implying that epitopes of this size might constitute viable vaccine components. Short oligosaccharides conjugated to suitable immunogenic proteins have been synthesized by two distinct approaches one of which is well suited to multigram synthesis. Tetanus toxoid was chosen as a carrier protein for its ability to induce a vigorous hapten specific IgG response and for compatibility with human vaccine applications. Preliminary data show that rabbits immunized three times with a trisaccharide glycoconjugate produce sera with ELISA...

The History Of Aids Psychiatry

In 1981, previously healthy young men and women were being admitted with pneumonia and severe respiratory distress to the intensive care unit of our municipal academic medical center in New York City. They were dying of respiratory failure. The reason for these deaths was not clear. At about the same time, Michael Gottlieb, an immunologist in an academic medical center in Los Angeles, California, began to investigate the reasons for the occurrence of Pneumocystis carinii pneumonia (PCP) in five previously healthy young men. On June 5, 1981, his report of these cases was published in the Morbidity and Mortality Weekly Report (CDC, 1981a). Gottlieb's first patients were also described as having cytomegalovirus and candida infections. In a more detailed article, published on December 10, 1981, in the New England Journal of Medicine, Gottlieb and colleagues (1981) linked an immune deficiency with this new cluster of infections. They presented evidence for an association ofthe illnesses...

The Paradox of Foreign Antigen Recognition by Regulatory T Cells

To complicate matters further, recognition of foreign antigen by the naturally arising CD25+ T cell population has also been demonstrated using immunization with hapten 2,4-dinitrofluorobenzene, or infection with Candida albicans or Leishmania major (Belkaid et al. 2002 Dubois et al. 2003 Montagnoli et al. 2002). For example, adoptive transfer studies revealed that the Leishmania-reactive CD25+ T cells accumulating at the sites of infection were derived primarily from the naturally arising CD25+, and not CD25-, donor T cells. In fact, it was observed that persistent immunologic memory to Leishmania as well as Candida requires the presence of these adaptive TR

The Discovery of Posaconazole

Fluconazole (22) is orally active, and is very widely used against Candida and Cryptococcus infections however, it lacks activity against the important pathogen Aspergillus. Ketoconazole (23) was the first example of an orally active antifungal used in the clinic, but exhibits hepatotoxicity and also interferes with testosterone biosynthesis. Our aim at the SPRI was to discover an orally active antifungal, comparable to fluconazole (22) in its activity against Candida and also having activity against fluconazole-resistant strains of Candida glabrata and Candida krusei. In addition, our compound should have activity against Aspergillus, and should be superior to itraconazole (24), be safe, and not be an inducer of human cytochrome P450 enzymes. In our initial studies the importance of the aromatic spacer group -OR, and the presence of an azole moiety for its broad-spectrum activity, potency, and oral bioavailability, became apparent. Among the initial compounds synthesized, SCH 450 1 2...

Fungal Pathogens Including Emerging Fungi

Fungal infections occur with increasing frequency when neutropenia is prolonged (see below). In the past, most fungal infections were caused by species of Candida or Aspergillus. Candida are frequent colonizers of skin, oropharynx, and the gastrointestinal tract, and may cause localized or disseminated infection. Aspergillus spores are widespread in the environment and can also be nosocomial pathogens, particularly in relation to building construction. Sinus or airway colonization may become an invasive infection in the setting of neutrope-nia. Those with a history of marijuana use, gardening, farming, or construction work are at a higher risk for being colonized. In recent years, resistance to antifungal agents has increasingly occurred. Fluconazole has been used for therapy or prophylaxis of yeast infections, as it avoids the toxicities of amphotericin B. However, pathogens such as Candida glabrata (frequently fluconazole resistant) and Candida krusei (always resistant) have emerged...

Indwelling iv catheters

Tunneled catheters are subject to several types of infection exit site cellulitis, bacteremia with or without external signs, tunnel infection, and septic thrombophlebitis. The most common causative organisms are coagulase-negative staphylococci, but Staphylococcus aureus, Enterococcus, Gram-negative bacilli, other skin flora, yeast, and occasionally nontuberculous mycobac-teria also may be causative organisms. Decisions regarding catheter removal often must be made in the face of fever, neutropenia, and need for multilumen access. In general, tunnel infections require catheter removal regardless of the organism, and pain over the tunnel may be the only sign in a neutropenic patient. In Candida, VRE, or Bacillus infection, it is particularly important to remove the catheter, and it is often desirable to do so for Staphylococcus aureus and Gram-negative bacilli. On the other hand, in the absence of tunnel infection, coagulase-negative staphylococcal infection can often be cleared...

Antifungal Therapy Timing of antifungal therapy

Lipid formulations of amphotericin, including amphotericin B lipid complex (ABLC) and liposomal amphotericin, are less nephrotoxic than conventional amphotericin, but are costly infusion-related reactions may still occur (less so with liposomal amphotericin). Fluconazole is primarily useful for prevention of infection with sensitive Candida species, and does not have activity against Aspergillus. Centers with extensive flu-conazole use may see a rise in fluconazole-resistant yeast, including C. glabrata and C. krusei. Itraconazole has activity against Aspergillus and is sometimes used as antifungal prophylaxis. However, oral tolerability is decreased in patients with chemotherapy-induced nausea, and the i.v. formulation cannot be used in patients with renal dysfunction. Voriconazole is a broad-spectrum antifungal agent with both i.v. and oral formulations. It covers many Candida species resistant to other azoles, has excellent activity against Aspergillus, and also a number of...

Crosslinked Enzymes And Novel Catalytic Materials

Chemically, CLECs are significantly more stable against denaturation by heat, organic solvents, and proteolysis than the corresponding soluble proteins. In certain cases the enzyme crystal may even be more active than the same enzyme in solution. For example, CLECs of lipases and subtilisin formulated with surfactants exhibited specific activity in organic solvents higher than that of native enzymes. Crystals of Candida Rugosa Lipase (CRL)

Materials and Methods

Microbiological study controls in phase 1 were internal controls for amplification (DNA from Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, P. aeruginosa ATCC 35218, Candida albicans ATCC 90028) whole blood of 20 healthy blood donors, and dialysis ultrapure water collected from different points of the treatment plant.

AIRE a model gene for the development of organspecific autoimmune diseases

A model gene for a general predisposition for organ-specific autoimmune diseases is the autoimmune regulator (AIRE), which was recently cloned. Severe reduction of AIRE function causes a genetic disease, called autoimmune polyendocrine syndrome type 1 (APS1) 13 . Patients with APS1 usually develop mucocutaneous candidiasis at least once in their lives and a broad spectrum of different autoimmune diseases 20 . The most frequent autoimmune diseases are hypoparathyroidism (80 ) and adrenal insufficiency (70 ). In addition to endocrine disorders, ectodermal dystrophies are frequently noted as well as hepatogastroin-testinal dysfunction (Table 23.1). Ten to twenty per cent of patients with APS1 develop AIH. Mucocutaneous candidiasis 100

What are the risks of longterm inhaled steroid use

Local side effects such as oral candidiasis and hoarseness are quite frequent, and systemic side effects are perhaps not as infrequent as is often believed in asthma. In EUROSCOP, an excess 6 developed bruises on the forearms > 5 cm in diameter at least once during the trial 14 , and although it was firmly stated that no other systemic side effects were seen, bruises are markers of systemic effects and it is likely that the study was underpowered to detect more deleterious effects. In a subsample in EUROSCOP, no effects of treatment with ICS were seen on bone mineral density, but as long-term treatment will often be offered to patients with an unfavourable osteoporosis profile (smoking, minimal physical activity and inappropriate nutrition), this potential problem has not been solved. In fact, in LHSII an increased loss of bone mineral density was found in the femoral neck, but not in the lumbar spine, and this should indicate a need for caution. Wisniewski et al. 30 showed an...

HE Spinnler and MN Leclercq Perlat

The main microorganisms able to raise the pH of Camembert type cheeses are yeasts and Penicillium camemberti. Normally, owing to the low buffering capacity of the curd 22 , consumption of lactate changes the pH at the surface very easily, during the first phase of ripening. Yeasts and G. candidum develop quickly immediately after moulding, consuming residual lactose and starting to consume the lactate produced by lactic acid bacteria. The main yeasts found in these cheeses are Debaryomyces hansenii, Kluyveromyces lactis and Kluyvero-myces marxianus. G. candidum grows somewhat later than the yeasts. Other species such as Saccharomyces cerevisiae, Yarrowia lipolytica and Candida spp. are also sometimes present. These organisms may have different metabolisms for example Kluyveromyces spp. will consume residual lactose first and, only after its exhaustion, lactate will be metabolised though Debaryomyces will consume both simultaneously. In mould-ripened cheese it is not uncommon that the...

Innate and Adaptive Immunity to Fungi

Cell-mediated immunity is the major mechanism of adaptive immunity against fungal infections. Histoplasma capsulatum, a facultative intracellular parasite that lives in macrophages, is eliminated by the same cellular mechanisms that are effective against intracellular bacteria. CD4+ and CD8+ T cells cooperate to eliminate the yeast forms of C. neoformans, which tend to colonize the lungs and brain in immunodeficient hosts. Many extracellular fungi elicit strong TH17 responses, which are driven in part by the activation of dendritic cells by fungal glucans binding to dectin-1, a receptor for this fungal polysac-charide, and this results in the production of TH17-inducing cytokines (IL-6, IL-23) from the dendritic cells (see Chapter 9). The TH17 cells stimulate inflammation, and the recruited neutrophils and monocytes destroy the fungi. Candida infections often start at mucosal surfaces, and cell-mediated immunity is believed to prevent spread of the fungi into tissues. TH1 responses...

Defects in Phagocytic Cell

Neutropenia may be caused by replacement of the bone marrow by CLL cells, suppression by tumor products, or, most often, myelosuppressive chemotherapy. Although alkylating agents cause myelosuppression, resulting in neutropenia, most conventional regimens usually do not cause severe or prolonged neutropenia (9). Although not studied in CLL patients specifically, the risk of infection is inversely related to the degree of neutropenia and is directly related to its duration (10). Also, the risk of hematogenous dissemination is related to the degree of neutropenia. Neutropenia is a pre-eminent factor in predisposing to most bacterial infections and also to systemic Candida and mold infections. Furthermore, response to appropriate therapy, especially in fungal infections, is largely dependent on neutrophil recovery.

Infections Associated With Purine Analog Therapy

Was substantially shorter for the latter group. Considering only the 188 patients who received fludarabine alone, 77 experienced at least one febrile episode, and 29 developed a major infection. The most frequent sites of infection were the lower respiratory tract (14 of patients) and skin and soft tissue (7 of patients). The most frequent infections were herpes zoster, occurring in 13 of patients, followed by herpes simplex (10 ), Gram-positive cocci (8 ), Gram-negative bacilli (5 ), Candida species (3 ), and P. carinii (0.5 ). Only 19 of major infections occurred when patients were neutropenic, and none of them died of infection. Infections during cladribine therapy may be caused by neutropenia or lymphopenia. In one study of patients with hematological malignancies, 68 of patients who developed neutropenia had fever or infection. The frequency of infection among patients with hematological malignancies almost doubled during the 6 mo following the first course of cladribine compared...

Antimicrobial Prophylaxis

In recent years, ciprofloxacin has been used most extensively for prevention of bacterial infections in patients with prolonged severe neutropenia. Although it has reduced the frequency of Gram-negative bacterial infections, its use has been associated with an increase in Grampositive infections and the emergence of resistance among Gram-negative bacilli. Also, in most studies, its use did not reduce the frequency of fever and empiric antibacterial therapy. Hence, its use should be restricted to those patients who are likely to experience severe neutropenia following chemotherapy. Outpatients at risk for pneumococcal or Listeria infections could be given a supply of amoxicillin-clavulanate to be initiated at the onset of fever, as should splenectomized patients (3). Since serious fungal infections occur rather infrequently in CLL patients, it is difficult to justify the routine use of antifungal prophylaxis, especially since it has been associated with colonization by resistant...

Terminology and Scope

In biology, the concept of genome doubling is usually expressed as tetraploidiza-tion or autotetraploidization, and the both the doubled genome and its doubling descendant are called tetraploid, even though, generally, the descendants soon undergo a process called (re-)diploidization and function as normal diploids, still carrying a full complement of duplicate markers that evolve independently of each other. Though unambiguous in biological context, implicit in this terminology are many assumptions that are not pertinent to our study. In the yeast data we study here, for example, Saccharomyces cerevisiae exists during most of its life cycle as a haploid, only sometimes as a diploid, while Candida glabrata exists uniquely as a haploid. The marker complement of a genome may also double by another process, allotetraploidization, or fusion of two different genomes, a kind of hybridization that is probably at least as important biologically as the doubling of a single genome we focus on...

Pretransplant Evaluation

A careful pretransplant infectious disease history should be obtained in all HSCT candidates (Table 99.1). This should include a history of prior bacterial, mycobacterial, and opportunistic infections, especially invasive fungal infections produced by Aspergillus or Candida species. In those with prior invasive fungal disease, a careful clinical and radiographic evaluation should be performed to exclude residual active disease, which would require aggressive treatment prior to HSCT. Antimicrobial susceptibility profiles of recent bacterial pathogens should be noted, as patients may remain colonized with these organisms. Patients with a prior history of tuberculosis, exposure to tuberculosis, or positive skin test for tuberculosis should be evaluated clinically and with chest radiograph for evidence of active disease. A travel history should be obtained to identify potential exposure, even in the remote past, to Strongyloides stercoralis, which may reactivate in the face of...

Prophylaxis And Therapy

Routine decontamination of the gut is not recommended for HSCT candidates.2 The use of oral fluoroquinolones and an agent active against Gram-positive cocci in asymptomatic neutropenic patients reduces the occurrence of Gram-positive and Gram-negative bacteremias, but has no impact on fever-related morbidity or infection-related mortality.33 A novel strategy to reduce the occurrence of oral mucositis after intensive chemotherapy using palifermin (recombinant human keratinocyte growth factor) has demonstrated promise. In a double-blind, placebo-controlled trial involving patients with hematologic malignancies, palifermin recipients had less severe mucositis, a shorter duration of mucositis, and a lower incidence of fever during neutropenia and bacteremia compared with placebo recipients.34 Acyclovir prophylaxis is indicated for all HSV-seropositive HSCT candidates and has been shown to reduce the occurrence of viral reactivation.35 Prophylaxis should commence at the initiation of the...

Genome Doubling in Yeast

Wolfe and Shields 10 discovered an ancient genome doubling in the ancestry of Saccharomyces cerevisiae in 1997 after this organism became the first to have its genome sequenced 7 . According to 8 , the recently sequenced Candida glabrata 4 shares this doubled ancestor. We extracted data from YGOB (Yeast Genome Browser) 3 , on the orders and orientation of the exactly 600 genes identified as duplicates in both genomes, i.e., 300 duplicated genes.

Congenital Primary Immunodeficiencies

Diagnosed by reduced levels of serum immunoglobulin (Ig), defective antibody responses to vaccination, and, in some cases, reduced numbers of B cells in the circulation or lymphoid tissues or absent plasma cells in tissues (see Table 20-1). Abnormalities in T lymphocyte maturation and function lead to deficient cell-mediated immunity and may also result in reduced antibody production. Primary T cell immunodeficiencies are diagnosed by reduced numbers of peripheral blood T cells, low prolif-erative responses of blood lymphocytes to polyclonal T cell activators such as phytohemagglutinin, and deficient cutaneous delayed-type hypersensitivity (DTH) reactions to ubiquitous microbial antigens, such as Candida antigens. Defects in both humoral and cell-mediated immunity are classified under severe combined immunodeficiencies. In the following sections, we describe immunodeficiencies caused by inherited mutations in genes encoding components of the innate immune system or in genes required...

Predisposing Factors In Maternal Infection

Candida vulvovaginitis occurs in about 25 of pregnant women however, this is usually not associated with obstetrical complications (10,11). Although infrequent, ascending infections from the vagina and cervix can occur, leading to infection of the placenta. Because of the presence of chorioamnionitis or funisitis, candidemia and sepsis may occur in the pregnant woman, but this is rare. Invasive disease would be unlikely unless the mother was immunosuppressed. Such conditions would include human immunodeficiency virus, immunosuppressive therapy, prolonged corticosteroid or broad-spectrum antibiotic use, burns, trauma, and indwelling vascular and urinary catheters.

Predisposing Factors In Fetal And Neonatal Infection

Despite its presence in 25 of all pregnant women, isolation of Candida from the placenta is rare (12,13). Baley reported an incidence of less than 1 (14). In the presence of chorioamnionitis, fetal infection can occur and presents as congenital cutaneous candidiasis (CCC). Risk factors for congenital infection include early preterm birth, the presence of a foreign body such as an intrauterine device or cervical sutures, and possibly diagnostic amniocentesis (6,12). Factors that do not appear to play a role in congenital candidiasis are maternal age, prolonged rupture of membranes, diabetes, urinary tract infection, parity, and antibiotic, tocolytic, or corticosteroid therapy (15). The role of congenital candidiasis in precipitating preterm labor or premature rupture of membranes remains unknown and warrants further investigation (16,17). Colonization has been shown to be a significant risk factor for mucocutaneous and invasive candidiasis. In one study, one third of the colonized...

Prenatal Evaluation

Any pregnant woman with a vaginal discharge or inflamed vulvovaginal area should be evaluated for Candida. Candida vulvovaginitis is the second most common cause of vaginitis after bacterial vaginosis. Many women are asymptomatic, but the classic signs are a profuse, pruritic, thick, white, curdlike discharge associated with dysuria, dys-pareunia, and pruritus ani. The diagnosis of Candida vulvovaginitis is a clinical diagnosis that is confirmed by culture and microscopic detection of the yeast. A drop of the cervicovaginal fluid should be immersed in a 10 potassium hydroxide (KOH) preparation on a glass slide with a coverslip for microscopic examination. Sometimes, this slide is heated before examining it under the microscope. The presence of ovoid budding yeast cells 3-7 m in diameter, seen sometimes with pseudohyphae, can make a presumptive diagnosis. The diagnosis is confirmed by isolating Candida from the cervicovaginal secretions cultured on Sabouraud's dextrose agar, which is...

Other CAM Therapies

Multiple CAM therapies are unstudied or unlikely to be beneficial at the same time, they are possibly unsafe, expensive, or labor-intensive. Because of these concerns, these therapies should be fully investigated and well understood before use calcium EAP, Candida (yeast) therapy, chelation therapy, dental amalgam removal, DHEA, hyperbaric oxygen, Prokarin, and toxin avoidance.

Direct Diagnostic Assays For Evaluating The Mother And Infant

A number of immunological and serologic diagnostic tests have been investigated because of the difficulty with interpreting the isolation of Candida from the urinary and respiratory tracts as well as confirming the diagnosis of invasive candidiasis, especially in immunocompromised hosts. Some of these tests look promising however, most are not commercially available for routine use. Several rapid antigen detection assays are available, including latex particle agglutination (LPA), enzyme immunoas-say, and radioimunoassay. Most assays detect mannan as the main Candida antigen. Some of these tests have a high rate of false negatives. The LPA is the easiest to perform and has been shown to be useful in quantitation of Candida. Using a titer of 1 4 or above as a positive result, it has an excellent specificity of more than 90 but at best a sensitivity of only 70 . The LPA is more useful for monitoring response to therapy than diagnosis because there is some correlation with decreasing...

Acquired Secondary Immunodeficiencies

Patients with advanced widespread cancer are often susceptible to infection because of impaired cell-mediated and humoral immune responses to a variety of organisms. Bone marrow tumors, including cancers metastatic to marrow and leukemias that arise in the marrow, may interfere with the growth and development of normal lymphocytes and other leukocytes. In addition, tumors may produce substances that interfere with lymphocyte development or function. An example of malignancy-associated immunodeficiency is the impairment in T cell function commonly observed in patients with a type of lymphoma called Hodgkin's disease. This defect was first characterized as an inability to mount a DTH reaction on intradermal injection of various common antigens to which the patients were previously exposed, such as Candida or tetanus toxoid. Other in vitro measures of T cell function, such as proliferative responses to polyclonal activators, are also impaired in patients with Hodgkin's disease. Such a...

PCT indicator of bacterial and fungal infections

Interestingly enough, PCT correlates with the severity and activity of the infection. Assicot et al. 1 describe values up to 53 ng ml in patients with severe systemic bacterial fungal infections. Local bacterial fungal infections resulted only in a moderate, or no, rise in PCT (0.3-1.5 ng ml). In the case of an encapsulated process or infections limited to one organ - such as pneumonia or peritonitis - PCT levels were only slightly increased (1-3 ng ml) 1 . The authors' own studies with heart, lung or liver transplant patients have confirmed these results (Tables 48.1 and 48.2). In liver transplant patients, PCT was found to reach slightly higher values (local infection 2.2 ng ml systemic infection 11.9 ng ml) than in patients after heart or lung transplantation (local infection 0.6 ng ml systemic infection 10.5 ng ml). PCT not only reacts sensitively to severe bacterial infections but also to those infections of parasites and fungi. As a consequence of the immunosuppressive therapy,...

PCT and immunosuppressiondeficiency

In septic patients, with and without immunosuppression, PCT does not differ during the first 3 days of the disease. However, immunocompromised patients already show low PCT values between days 3 and 5, while, in patients with a normal immune system, PCT levels do not drop until day 5 9 . These observations are in complete contrast to reports of exceedingly high PCT values of 103 ng ml in a 4-year-old liver transplanted girl with disseminated candidiasis who received a combined immunosuppressive therapy consisting of cyclosporin, azathioprine and corticosteroids 12 . PCT was not influenced by these immunosuppressive agents. The only exception appeared to be immunosuppressive therapy with OKT 3, which increased PCT release.

Selected Examples Of Potential Medical Applications Of Liposomes

A highly successful use of a liposomal carrier system in infectious diseases which seems to be more promising from a commercial point of view is the therapy of systemic fungal infections with amphotericin B (AMB) incorporated into liposomes. Systemic fungal infections occur frequently in patients suffering from cancer or an immunodeficiency disorder (e.g., AIDS). For example, fungi, in particular Candida albicans, are responsible for about 20 of the lethal infections in leukemia patients. The use of AMB, a polyene antibiotic, is hindered by acute (fever, chills) and chronic toxicity to kidneys, central nervous system, and hematopoietic system (Miller and Bates, 1969). Amphotericin B has a certain preference to interact with fungal membranes due to their ergostefol content. However, it also binds to the cholesterol-containing mammalian membranes resulting in toxicity. Despite the serious side effects, limited efficacy and the development of several new antifungals, AMB is still the...

Defects in Innate Immunity

Deep-seated abscesses and oral stomatitis are also common. Defects in TLR signaling and in type I interferon signaling may contribute to recurrent pyogenic infections as well as to severe viral infections defects in IL-12 and the IFN-y pathway are linked to susceptibility to intracellular pathogens, particularly mycobacterial infections.

Types Of Bioprocesses

Gaden classified fermentation processes into three types. In type 1 process the production is due to result of primary metabolism. The rate of product formation is directly related to the rate of substrate consumption and also to the rate of cell mass produced. Examples of aerobic systems that follow this classification are acetic acid (using Gluconobacter suboxidans), single-cell protein (using Candida utilis, S. cerevisiae) and baker's yeast (using S. cerevisiae). The first system is operated under batch mode. The second under batch or fed batch mode, while the third system is operated at fed batch mode. Examples of anaerobic processes are ethanol (S. cerevisiae, Zymomonas mobilis), acetone butanol (C. acetobutylicum), lactic acid (Lactobacillus bul-garicus) and propionic acid (Propionibacterium shermanii). The first two products are run in continuous mode of operation and the next two in batch mode.

Fetal Inflammatory Response Of Umbilical And Chorionic Plate Vessels

Umbilical Cord Microabscesses (Candida Funisitis) The most common congenital fungal infection is caused by Candida sp. Although Candida vaginitis is a very common complication of pregnancy, it rarely results in chorioamnionitis. The risk of Candida colonization is increased with cerclage or the presence of other foreign bodies and coexistent infection (64). Term infants may be colonized but are usually asymptomatic. Candida funisitis is life-threatening in a preterm infant. The diagnosis of Candida infection is often made on the gross examination of the umbilical cord. The cord surface is studded with 0.05- to 0.2-cm yellow-white plaques that seem to be just under the amnion (Fig. 7A). Histological confirmation may be difficult if the exact area from the cord is not submitted. Acute inflammation from the cord vessels extends to the basement membrane of the amnion epithelium and forms a microabscess. The yeast and pseudohyphae are very difficult to see on routine stains and usually...

Medical Evidence

Erythema and an erosion of the hard palate have also been described after fellatio (74,75), but the reliability of such findings is questionable. Indeed, in one such case, the mucositis was eventually diagnosed as oral candidiasis contracted from direct contact with an infected penis (75).

Architecture

Macronuclei of Oxytricha nova are protected. A protein has been isolated that has led to a model of telomere end protection based on a single protein species that would bind and sequester the single-strand overhang. Until recently, few examples of single-stranded telomere overhang binding proteins outside of Oxytricha were known. One such example was found in Candida parapsilosis (171), where a single-stranded binding protein was shown to bind a single-stranded overhang of linear mitochondrial DNA. Recently, a single-stranded telomere-binding protein termed Pot1 (protection of telomeres 1) was isolated and characterized in fission yeast and human cells (28). Pot1 has high affinity for single-stranded DNA with the sequence motif of Schizosaccharomyces pombe telomeric repeat or the G-strand overhang in mammalian telomeres. It has been proposed that Pot1 might serve to protect the telomere end from degradation and regulate the ability of telomerase to elongate the telomere. Whether this...

Radiographic Studies

The abdominal CT scan is helpful in patients with abdominal pain, as the physical exam may lack classic signs. The CT can reveal abscesses, adenopathy, intestinal wall thickening, or phlegmon suggestive of typhlitis, lesions of hepatosplenic candidiasis, and other conditions.8

Skin lesions

As disseminated infections with filamentous fungi or mycobacteria are difficult to diagnose in a timely fashion, biopsies and cultures of suspicious skin lesions are often helpful. Pseudomonas, Candida spp., and Fusarium are particularly likely to be associated with skin lesions. Lesions of ecthyma gangrenosum most often reflect disseminated infection with Pseudomonas. Disseminated candidiasis can present with nodular or papular scat

Lipids

All patients were under antiretroviral treatment and secondary prophylaxis for opportunistic infections (6 for MACD, 3 for neurotoxoplasmosis, 5 for PCP, 3 for CMV, 3 for candida). Patients with intractable diarrhoea, acute opportunistic infections, and or a Karnofsky score < 50 were excluded. The caloric needs were calculated for each patient according to a modified Harris-Benedict equation, and extra calories were prescribed in relation to the patient's clinical condition. Caloric

Yeasts

Yeasts are the initial organisms to grow on the surface of smear-ripened cheeses directly after manufacture and salting brining. The conditions of low pH ( 4.9-5.2), relatively low ripening temperature and high salt concentration on the cheese surface favour their growth. Although considerable variation occurs, the most prevalent yeasts reported in many smear cheeses include Debaryomyces hansenii, Candida spp., Trichosporon spp., Yarrowia lipolytica, Kluyveromyces spp., Rhodotorula spp. and Torulaspora spp. Geotrichum candidum is also prevalent and has the characteristics of both a yeast and a mould. A succession of different species may also occur during ripening.

Direct Combustion

Traditional fermentation yeasts, such as S. cerevisiae, are not adapted to utilize inulin. However, a number of yeast strains have been discovered with inulinase activity, which can both hydrolyze inulin and ferment the resulting sugars (Echeverrigaray and Tavares, 1985 Guiraud et al., 1981a, 1981b Padukone, 1996). It is therefore possible to produce ethanol from Jerusalem artichoke juice using these yeasts in a single vessel, without prior hydrolysis or saccharification, in a process called simultaneous saccharification and fermentation (SSF) (Figure 7.1b). In practice, enzymatic hydrolysis may still be conducted under acidic conditions, for instance, to utilize the enzymes present in the plant material and to start saccharification prior to the addition of inulinase-producing yeasts. High rates of ethanol production from tuber extracts have been obtained with inulin-fermenting strains of K. marxianus, K. fragilis, Candida pseudotropicalis, C. kefyr, C. macedoniensis, Saccha-romyces...

Fungal Infections

P. carinii (now considered to be a fungus) occasionally caused pneumonia in CLL patients prior to the introduction of fludarabine therapy, but most cases of Pneumocystis pneumonia have occurred in patients who were treated with fludarabine plus prednisone (46,58). The association of this infection with adrenocorticosteroid therapy is well recognized hence, the role of fludarabine is less certain. Systemic Candida infections have been reported in patients receiving fludarabine, as well as sporadic cases of infection caused by Aspergillus species, Fusarium species, Histoplasma capsulatum, and Onchocronis species (59). It is somewhat surprising that superficial Candida infections and Aspergillus sinusitis have not been reported more frequently, the former infections being associated with low CD4+ lymphocyte counts and the latter with neutropenia and adrenal corticosteroid therapy.

Candida species against influenza of health care workers and at-risk HSCT candidates pretransplant, and influenza prophylaxis on HSCT units during outbreaks.219 Influenza, parainfluenza, and RSV may produce lower respiratory tract infection in the early posttransplant period with significant morbidity and mortality2021 tracheobron-chitis and pneumonia are usually heralded by the onset of upper respiratory tract symptoms, such as rhinor-rhea, sinus congestion, and sore throat. Lymphopenia appears to be a risk factor for progression to lower respiratory tract infection in HSCT recipients with influenza.21 Other pathogens, such as Aspergillus species, are frequently isolated in patients with influenza involving the lower respiratory tract. Antiviral therapy in HSCT recipients with influenza with a neuraminidase inhibitor is preferred to amanti-dine or rimantidine, as neuraminidase inhibitors appear to shorten the duration of viral shedding.21 Inhaled ribavirin and intravenous...

The Organism

Candida spp are ubiquitous dimorphic yeasts that can exist as 2- to 5- im round-oval cells called blastospores, which reproduce by budding. They have the ability to produce pseudohyphae, which are filamentous processes elongating from the cells. Fifty years ago, these round vegetative cells were considered nonpathogens. Some Candida spp, especially Candida albicans, exist as normal flora on skin and in the lower gastrointestinal (GI) tract and female genital tract. However, therapeutic and technological advances in medicine have enabled these yeasts to become true pathogens, especially in the immunocompromised hosts. In addition to causing insignificant and mild mucocutaneous infections in the normal host, these yeasts cause invasive and life-threatening disease affecting almost any organ. Of the 200 Candida spp, C. albicans has been the most common, accounting for about 60-80 of neonatal infections. Other Candida spp that act as human pathogens include Candida tropicalis, Candida...

Colonization

The fungal colonization rate for low birth weight infants (< 1500 g) ranges from 19 to 47 in the first 24 hours of life (3,5,8). In one study, the most common site of early colonization (i.e., at birth or first 24 hours of life) was the GI tract, as demonstrated by positive rectal fungal cultures. At birth, 86 had rectal colonization, followed by 60 with tracheal colonization and 57 with oropharyngeal colonization (5). The endotra-cheal acquisition at birth represents aspiration of the yeast during labor and delivery. Oropharyngeal acquisition at birth was not as frequent as rectal acquisition. At 1-2 weeks of age, the detection of yeast in the rectum and oropharynx was less likely. Late colonization was more often detected in the groin cultures. By 2 weeks of age, 64-85 of low birth weight neonates were colonized with Candida in the groin sites.

Antibiosis

On the contrary, there are indications that immediate administration of antibiotics to children with otitis and tonsillitis resulted in a relapse rate after four weeks that was twice as high as in children without treatment with antibiotics (KVH aktuell 16 1996). Shifts in the composition of symbiotic microbial populations are direct consequences of the extensive use of antibiotics. Postantibiotic colitis is caused by Clostridium difficile and is the result of antibiotic treatment. It has also been documented that the propagation of pathogenic fungi, such as Candida albicans, is a result of antibiotic treatment. The significant increase in at-opic disorders in industrialized countries has been correlated in recent studies with excessive hygiene, antibiotic decontamination, and lack of contact with the microbial environment. The fecal flora in atopic patients and, above all, in children exhibits considerable abnormalities these abnormalities are evident in a significant propagation of...

Fetal Evaluation

Although sampling of amniotic fluid obtained by transabdominal amniocentesis for prenatal detection of Candida may allow earlier diagnosis and intervention for invasive neonatal candidiasis as well as obstetrical intervention, this is not routinely recommended. Further investigation regarding obstetrical and perinatal management of mother and fetus is needed for the detection of Candida in amniotic fluid. The use of antifungal agents for chemoprophylaxis in the mother for preventing CCC or neonatal candidiasis and the use of oxytocin vs the continuation of tocolytic administration need further study.

Perinatal Evaluation

Although intrauterine infection is rare, chorioamnionitis may lead to preterm labor, congenital and neonatal infections, Candida sepsis, and endometritis. In intrauterine infection, gross examination of the placenta and umbilical cord will reveal a yellow exudate on the placental surface and areas of necrosis and discrete, yellow macular lesions along the cord near the funicular vessels. Histological examination of the cord and placenta may reveal spores and pseudohyphae on periodic acid-Schiff stain, Gomori methenamine silver stains, toluidine blue, or Gram stain. There is an inflammatory infiltrate of neutrophils, lymphocytes, and histiocytes as well as microabscess formation.

Neonatal Evaluation

Maternal Candida vulvovaginitis may result in colonization of the newborn or mucocutaneous, invasive candidiasis or congenital candidiasis. Congenital candidiasis can present in infants as CCC or invasive disease (6,12,17,21). CCC is a severe cutaneous candidiasis that is far less common. Mucocutaneous candidiasis consists of oral thrush or diaper dermatitis or both. Oral thrush typically presents on the days 7-10 of life as whitish patches (resembling milk curds) anywhere on the oral mucosa. The lesions can extend to the posterior pharynx but most often are located on the buccal mucosa, tongue, and palate. Scraping of these lesions results in a denuded erythematous base. Microscopic examination of these scrapings placed in 10 KOH suspension on a glass slide reveals blastospores or oval-round yeast cells and pseudohyphae. The diagnosis of oral thrush is based on clinical findings. Even though this is a presumptive diagnosis, routine culturing or microscopic examination of the...
