Early mycological treatment failure in AIDS-associated cryptococcal meningitis. (1/529)
Cryptococcal meningitis causes significant morbidity and mortality in persons with AIDS. Of 236 AIDS patients treated with amphotericin B plus flucytosine, 29 (12%) died within 2 weeks and 62 (26%) died before 10 weeks. Just 129 (55%) of 236 patients were alive with negative cerebrospinal fluid (CSF) cultures at 10 weeks. Multivariate analyses identified that titer of cryptococcal antigen in CSF, serum albumin level, and CD4 cell count, together with dose of amphotericin B, had the strongest joint association with failure to achieve negative CSF cultures by day 14. Among patients with similar CSF cryptococcal antigen titers, CD4 cell counts, and serum albumin levels, the odds of failure at week 10 for those without negative CSF cultures by day 14 was five times that for those with negative CSF cultures by day 14 (odds ratio, 5.0; 95% confidence interval, 2.2-10.9). Prognosis is dismal for patients with AIDS-related cryptococcal meningitis. Multivariate analyses identified three components that, along with initial treatment, have the strongest joint association with early outcome. Clearly, more effective initial therapy and patient management strategies that address immune function and nutritional status are needed to improve outcomes of this disease. (+info)In vitro susceptibilities of clinical yeast isolates to the new antifungal eberconazole compared with their susceptibilities to clotrimazole and ketoconazole. (2/529)
The antifungal activity of eberconazole, a new imidazole derivative, against 124 clinical isolates of Candida comprising eight different species and to 34 isolates of Cryptococcus neoformans was compared to those of clotrimazole and ketoconazole. MICs of eberconazole, determined by the National Committee for Clinical Laboratory Standards standardized microbroth method, were equal to or lower than those of other azoles, especially for Candida krusei and Candida glabrata, which are usually resistant to triazoles. (+info)Topoisomerase I is essential in Cryptococcus neoformans: role In pathobiology and as an antifungal target. (3/529)
Topisomerase I is the target of several toxins and chemotherapy agents, and the enzyme is essential for viability in some organisms, including mice and drosophila. We have cloned the TOP1 gene encoding topoisomerase I from the opportunistic fungal pathogen Cryptococcus neoformans. The C. neoformans topoisomerase I contains a fungal insert also found in topoisomerase I from Candida albicans and Saccharomyces cerevisiae that is not present in the mammalian enzyme. We were unable to disrupt the topoisomerase I gene in this haploid organism by homologous recombination in over 8000 transformants analyzed. When a second functional copy of the TOP1 gene was introduced into the genome, the topoisomerase I gene could be readily disrupted by homologous recombination (at 7% efficiency). Thus, topoisomerase I is essential in C. neoformans. This new molecular strategy with C. neoformans may also be useful in identifying essential genes in other pathogenic fungi. To address the physiological and pathobiological functions of the enzyme, the TOP1 gene was fused to the GAL7 gene promoter. The resulting GAL7::TOP1 fusion gene was modestly regulated by carbon source in a serotype A strain of C. neoformans. Modest overexpression of topoisomerase I conferred sensitivity to heat shock, gamma-rays, and camptothecin. In contrast, alterations in topoisomerase I levels had no effect on the toxicity of a novel class of antifungal agents, the dicationic aromatic compounds (DACs), indicating that topoisomerase I is not the target of DACs. In an animal model of cryptococcal meningitis, topoisomerase I regulation was not critically important to established infection, but may impact on the initial stress response to infection. In summary, our studies reveal that topoisomerase I is essential in the human pathogen C. neoformans and represents a novel target for antifungal agents. (+info)Comparison of three commercial systems for identification of yeasts commonly isolated in the clinical microbiology laboratory. (4/529)
We evaluated three commercial systems (RapID Yeast Plus System; Innovative Diagnostic Systems, Norcross, Ga.; API 20C Aux; bioMerieux-Vitek, Hazelwood, Mo.; and Vitek Yeast Biochemical Card, bioMerieux-Vitek) against an auxinographic and microscopic morphologic reference method for the ability to identify yeasts commonly isolated in our clinical microbiology laboratory. Two-hundred one yeast isolates were compared in the study. The RapID Yeast Plus System was significantly better than either API 20C Aux (193 versus 167 correct identifications; P < 0.0001) or the Vitek Yeast Biochemical Card (193 versus 173 correct identifications; P = 0.003) for obtaining correct identifications to the species level without additional testing. There was no significant difference between results obtained with API 20C Aux and the Vitek Yeast Biochemical Card system (P = 0.39). The API 20C Aux system did not correctly identify any of the Candida krusei isolates (n = 23) without supplemental testing and accounted for the major differences between the API 20C Aux and RapID Yeast Plus systems. Overall, the RapID Yeast Plus System was easy to use and is a good system for the routine identification of clinically relevant yeasts. (+info)Variation in Microbial Identification System accuracy for yeast identification depending on commercial source of Sabouraud dextrose agar. (5/529)
The accuracy of the Microbial Identification System (MIS; MIDI, Inc. ) for identification of yeasts to the species level was compared by using 438 isolates grown on prepoured BBL Sabouraud dextrose agar (SDA) and prepoured Remel SDA. Correct identification was observed for 326 (74%) of the yeasts cultured on BBL SDA versus only 214 (49%) of yeasts grown on Remel SDA (P < 0.001). The commercial source of the SDA used in the MIS procedure significantly influences the system's accuracy. (+info)Comparative study of seven commercial yeast identification systems. (6/529)
AIMS: To compare the performance of seven commercial yeast identification methods with that of a reference method, and to compare the costs of the commercial kits. METHODS: Clinical yeast isolates (n = 52), comprising 19 species, were identified using Vitek, Api ID 32C, Api 20C AUX, Yeast Star, Auxacolor, RapID Yeast Plus system, and Api Candida and compared with a reference method which employed conventional tests. RESULTS: The percentage of correctly identified isolates varied between 59.6% and 80.8%. Overall, the highest performance was obtained with Api Candida (78.8%) and Auxacolor (80.8%). Among germ tube negative yeast isolates, Auxacolor and Api Candida both identified 93.1% of isolates correctly. All systems failed to identify C norvegensis, C catenulata, C haemulonii, and C dubliniensis. In comparison with Auxacolor, the Api Candida is less expensive and requires less bench time. CONCLUSIONS: Auxacolor and Api Candida appeared to be the most useful systems for identification of germ tube negative yeast isolates in clinical microbiology laboratories, although one should be aware that several germ tube negative Candida species cannot be identified by these systems. (+info)Binding energy and specificity in the catalytic mechanism of yeast aldose reductases. (7/529)
Derivatives of d-xylose and d-glucose, in which the hydroxy groups at C-5, and C-5 and C-6 were replaced by fluorine, hydrogen and azide, were synthesized and used as substrates of the NAD(P)H-dependent aldehyde reduction catalysed by aldose reductases isolated from the yeasts Candida tenuis, C. intermedia and Cryptococcus flavus. Steady-state kinetic analysis showed that, in comparison with the parent aldoses, the derivatives were reduced with up to 3000-fold increased catalytic efficiencies (k(cat)/K(m)), reflecting apparent substrate binding constants (K(m)) decreased to as little as 1/250 and, for d-glucose derivatives, up to 5.5-fold increased maximum initial rates (k(cat)). The effects on K(m) mirror the relative proportion of free aldehyde that is available in aqueous solution for binding to the binary complex enzyme-NAD(P)H. The effects on k(cat) reflect non-productive binding of the pyranose ring of sugars; this occurs preferentially with the NADPH-dependent enzymes. No transition-state stabilization energy seems to be derived from hydrogen-bonding interactions between enzyme-NAD(P)H and positions C-5 and C-6 of the aldose. In contrast, unfavourable interactions with the C-6 group are used together with non-productive binding to bring about specificity (6-10 kJ/mol) in a series of d-aldoses and to prevent the reaction with poor substrates such as d-glucose. Azide introduced at C-5 or C-6 destabilizes the transition state of reduction of the corresponding hydrogen-substituted aldoses by approx. 4-9 kJ/mol. The total transition state stabilization energy derived from hydrogen bonds between hydroxy groups of the substrate and enzyme-NAD(P)H is similar for all yeast aldose reductases (yALRs), at approx. 12-17 kJ/mol. Three out of four yALRs manage on only hydrophobic enzyme-substrate interactions to achieve optimal k(cat), whereas the NAD(P)H-dependent enzyme from C. intermedia requires additional, probably hydrogen-bonding, interactions with the substrate for efficient turnover. (+info)Intraspecies diversity of Cryptococcus laurentii as revealed by sequences of internal transcribed spacer regions and 28S rRNA gene and taxonomic position of C. laurentii clinical isolates. (8/529)
The intraspecies diversity of an opportunistic yeast pathogen, Cryptococcus laurentii, was revealed by analysis of the sequences of the internal transcribed spacer regions and the 28S rRNA gene. Ten strains of C. laurentii were grouped into two major phylogenetic groups and were further divided into at least seven species. Four of the strains isolated from patients did not represent a single species but showed heterogeneity. These results suggest that C. laurentii is a genetically heterogeneous species, and this must be taken into consideration when identifying C. laurentii clinical isolates. (+info)The symptoms of cryptococcosis vary depending on the location and severity of the infection. In lung infections, patients may experience fever, cough, chest pain, and difficulty breathing. In CNS infections, patients may experience headaches, confusion, seizures, and loss of coordination. Skin infections can cause skin lesions, and eye infections can cause vision problems.
Cryptococcosis is diagnosed by culturing the fungus from body fluids or tissue samples. Treatment typically involves antifungal medications, such as amphotericin B or fluconazole, which may be given intravenously or orally, depending on the severity and location of the infection. In severe cases, surgery may be required to remove infected tissue or repair damaged organs.
Preventive measures for cryptococcosis include avoiding exposure to fungal spores, practicing good hygiene, and maintaining a healthy immune system. For individuals with HIV/AIDS, antiretroviral therapy can help reduce the risk of developing cryptococcosis.
Overall, while rare, cryptococcosis is a serious opportunistic infection that can affect individuals with compromised immune systems. Early diagnosis and prompt treatment are essential to prevent complications and improve outcomes.
