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 ...19968804410
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 ...19968804793
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.19968807069
