torulopsis pneumonia. a case report and review of the literature. | torulopsis glabrata is a rare cause of pneumonia in immunocompromised patients. we herein describe the case of an elderly man who presented with fulminant torulopsis pneumonia and septic shock leading to death. we then review the literature, describe the clinical syndrome, and delineate an approach to diagnosis and treatment of torulopsis pneumonia. | 1996 | 8797445 |
evaluation of a commercial medium for identification of candida species. | chromagar candida (chromagar, france) was evaluated as a medium for the presumptive identification and isolation of yeasts using 1,537 isolates of medically important yeasts, including 970 candida albicans, 165 candida parapsilosis, 131 candida glabrata, 62 candida guilliermondii, 35 candida krusei, 32 candida tropicalis, 31 rhodotorula rubra, 23 trichosporon spp. (17 trichosporon beigelii), 17 candida famata, 16 candida pelliculosa, 10 pichia etchelsii, 10 saccharomyces cerevisiae, 8 candida lu ... | 1996 | 8801088 |
grisea, a putative copper-activated transcription factor from podospora anserina involved in differentiation and senescence. | podospora anserina is a filamentous fungus with a limited lifespan. lifespan is controlled by both environmental and genetic factors. using a combination of genetic and molecular approaches we have cloned one of these factors, gerontogene grisea. the cloned wild-type copy of grisea complements the altered morphological characteristics (e.g., colony and ascospore color), the defect in gametangia development, and the increased lifespan of the pleiotropic mutant grisea. a molecular analysis reveale ... | 1996 | 8804410 |
experimental evidences for a role of subinhibitory concentrations of rilopirox, nystatin and fluconazole on adherence of candida spp. to vaginal epithelial cells. | candidiasis is frequently localized in the mucosal epithelium which covers the vaginal and oral cavity. the pathogenicity of candida is correlated with its ability to adhere to epithelial cells and this is the resultant of both fungal and host cell properties and their physicochemical interactions. this study was performed to investigate the ability of subinhibitory concentrations (sub-mics) of rilopirox, a new antimycotic drug, to interfere with the adhesion of candida albicans, candida tropica ... | 1996 | 8804793 |
enhanced oxidative killing of azole-resistant candida glabrata strains with erg11 deletion. | the susceptibility of genetically defined candida glabrata strains to killing by h2o2 and neutrophils was assessed. fluconazole-susceptible l5l and l5d strains demonstrated survival rates higher than those of two fluconazole-resistant strains lacking the erg11 gene coding for 14 alpha-demethylase. fluconazole resistance can occur by mechanisms which increase fungal susceptibility to oxidative killing by h2o2 and neutrophils. | 1996 | 8807069 |
in vitro antimicrobial activity of pistacia lentiscus l. extracts: preliminary report. | the in vitro antimicrobial activity of pistacia lentiscus l. extracts was determined. pistacia lentiscus l. extracts were tested on bacteria (sarcina lutea, staphylococcus aureus and escherichia coli) and fungi (candida albicans, candida parapsilosis, torulopsis glabrata and cryptococcus neoformans). of the different plant extractions, decoctions showed the best antibacterial activity, but the activity against fungal cells appears to be much more interesting. | 1996 | 8808717 |

in vitro and in vivo antifungal activities of er-30346, a novel oral triazole with a broad antifungal spectrum. | er-30346 is a novel oral triazole with a broad spectrum of potent activity against a wide range of fungi. er-30346, with mics at which 90% of the strains tested are inhibited (mic90s) ranging from 0.025 to 0.78 microgram/ml, was 4 to 32 times more active than itraconazole, fluconazole, and amphotericin b against candida albicans, candida parapsilosis, and candida glabrata. against candida tropicalis, er-30346, with an mic90 of 12.5 micrograms/ml, was 2 to > 8 times more active than itraconazole ... | 1996 | 8891121 |
comparison of rapid testing methods for enzyme production with the germ tube method for presumptive identification of candida albicans. | the observation of germ tube production as a method for the presumptive identification of candida albicans has been in use for many years. methods have recently been developed for detecting the production of the enzymes l-proline aminopeptidase and beta-galactosaminidase by yeast isolates grown in culture. both enzymes are produced by c. albicans; other yeasts may produce either l-proline aminopeptidase or beta-galactosaminidase but not both enzymes. one hundred thirty-three clinical yeast isola ... | 1996 | 8897198 |
a specialized nucleosome modulates transcription factor access to a c. glabrata metal responsive promoter. | the ability of dna binding transcription factors to access cis-acting promoter elements is critical for transcriptional responses. we demonstrate that rapid transcriptional autoactivation by the amt1 cu metalloregulatory transcription factor from the opportunistic pathogenic yeast candida glabrata is dependent on rapid metal-induced dna binding to a single metal response element (mre). in vivo footprinting and chromatin-mapping experiments demonstrate that the mre and a homopolymeric (da x dt) e ... | 1996 | 8898199 |
immunological investigations in vaginal mycoses. | in 42 women with chronically recurrent and 20 women with acute candida albicans vulvovaginitis, as well as 14 women with candida glabrata vaginitis, the following investigations were carried out: determination of protein content and secretory immunoglobulin a (siga) in the cervicovaginal secretion by a self-modified elisa technique; determination of immunocells and cellbound iga in the cervicovaginal secretion by immunofluorescence and nephelometric analysis of iga in the serum. the results were ... | 1996 | 8909027 |
[serodiagnosis of fungal infection]. | serum samples from patients with candidiasis were assayed for candida mannan by the enzyme-linked immunosorbent assay using anti-candida albicans and anti-candida krusei antibodies (elisa, n = 81), for heat-labile glycoprotein by the latex agglutination test (cand-tec, n = 69), for d-arabinitol by the enzymatic fluorometric method, and for beta-d-glucan by the chromogenic substrate method (the g test, n = 14). the sensitivities and the specificities were 83% and 99% for mannan, 61% and 85% for h ... | 1996 | 8911065 |
isolation of a candida glabrata centromere and its use in construction of plasmid vectors. | a centromere has been isolated from candida glabrata by functional selection based on the lethality of the sup11 gene at high copy number. nucleotide sequence analysis revealed a centromeric structure similar to that of saccharomyces cerevisiae: the two highly conserved elements cdei (8 bp) and cdeiii (26 bp) are separated by a 79-bp a+t-rich element, cdeii. three centromere-bearing plasmid vectors with different selection markers have been constructed. these plasmids were highly stable in mitos ... | 1996 | 8917084 |
genetic speciation of candida isolates by arbitrarily primed polymerase chain reaction. | candida species are opportunistic human pathogens capable of causing a variety of clinical diseases. rapid and precise identification of candida to species level is essential for effective treatment and management strategies. conventional diagnosis of candidiasis is sometimes slow and variable. by using a random primer 5'-acgggccagt-3' in arbitrarily primed polymerase chain reaction, seven common candida species (i.e., c. albicans, c. guilliermondii, c. parapsilosis, c. krusei, c. lipolytica, c. ... | 1996 | 8931322 |
presence of a copper(i)-thiolate regulatory domain in the copper-activated transcription factor amt1. | the amt1 transcription factor from candida glabrata is activated by the formation of a tetracopper-thiolate cluster. recombinant amt1 (residues 1-110) is isolated as a cu,znamt1 complex. previous mapping studies [farrell et al. (1996) biochemistry 35, 1571-1580] revealed that the zn(ii) site is enfolded by an independent, n-terminal domain consisting of residues 1-40. one prediction from the mapping study is that the tetracopper cluster is enfolded by residues 41-110. a truncated amt1 peptide co ... | 1996 | 8931556 |
