[tinea unguis caused by nannizzia gypsea (+)].we describe a case of tinea unguis in a 20 year old female student from caracas. the peri-ungual skin of a thumb appeared altered first and, since 6 months, the lamina was being progressively invaded and destroyed. at the direct mycologic examination numerous, regular and irregular, hyaline fungal hyphae were visible. culture was performed 9 times: several molds did grow, among which, eight times, we got numerous colonies of a strain that has been identified to nannizzia gypsea (+). owing to the ...19836222260
phospholipid synthesizing enzymes of dermatophytes. iii. glycerol kinase of dermatophytes.glycerol kinase, the key enzyme for glycerol use in phospholipid synthesis, was identified in cytosolic fractions of 2 dermatophytes, microsporum gypseum and epidermophyton floccosum. ammonium sulfate was observed to activate and stabilize this enzyme in both dermatophytes. two ph optima, 8.0 and 10.5, were observed for both dermatophyte enzymes. glycerol kinase from m. gypseum was purified up to 33-fold with a 225% recovery by ammonium sulfate precipitation and gel filtration. the molecular wei ...19846325842

fusidane antibiotics produced by dermatophytes.isolates of microsporum canis, microsporum gypseum and epidermophyton floccosum were observed to produce antibacterial activities under cross-resistance to fusidic acid. the activity from e. floccosum was shown to be due to fusidic acid, diketofusidic acid and 3-ketofusidic acid. possible contributions of these antibiotics to microbial interaction during dermatophytosis is discussed.19836662806

identification, localization and possible role of calmodulin like protein in phospholipid synthesis of microsporum gypseum.calmodulin like protein has been identified for the first time in dermatophyte--m. gypseum (by specific radioimmunoassay). maximum amount of this protein was present in the early and mid log phase of growth and was mainly localized in the cytosolic fraction. cells treated or grown with calmodulin antagonists (phenothiazine and trifluoperazine) exhibited lower uptake of [14c]acetate or labelled phosphate into phospholipids. this is probably due to lower levels of calmodulin seen in these cells. o ...19957696325

antifungal evaluation of pseudolaric acid b, a major constituent of pseudolarix kaempferi.pseudolaric acid b [1] was isolated and identified as the main antifungal constituent of pseudolarix kaempferi using bioassay-directed fractionation. pseudolaric acid b was active against trichophyton mentagrophytes, torulopsis petrophilum, microsporum gypseum, and candida spp., while its methylated or hydrolyzed derivatives were not active against these same organisms. the minimum inhibitory concentrations and minimum fungicidal concentrations of pseudolaric acid b [1] against candida and torul ...19957760078

sds-page separation of dermatophyte antigens, and western immunoblotting in feline dermatophytosis.water-soluble antigens liberated from the disrupted mycelium of nine dermatophytes (seven isolates of microsporum canis, one each of microsporum gypseum and trichophyton mentagrophytes) were compared by analytical slab sds-page. no substantial differences were observed between the protein bands of the m. canis isolates, but certain distinctive bands were apparent in the other two species examined. western immunoblotting using m. canis-derived antigens separated by sds-page was used to investigat ...19947777039

mutants of dermatophytes resistant to ketoconazole.authors describe the frequency and properties of mutants resistant to ketoconazole, obtained from the dermatophytes microsporum gypseum and trichophyton mentagrophytes. spontaneous mutants occurred with the frequency of 10(-9) to spore and nucleus. ultraviolet radiation increased the frequency of mutants by two numeric orders. the resistance level was relatively small in both types of mutants (rl within the range of 2-5).19947778498

effect of ketoconazole on potassium pool, c-amp-release and ergosterol synthesis in resistant mutants of microsporum gypseum.the effect of ketoconazole (kk) on chosen biochemical indexes was studied in three mutants of dermatophyte microsporum gypseum (mg-155 wild strain) resistant to kk. fungistatic concentration of kk added to liquid cultivate medium increases significantly ergosterol pool and nonsignificantly demethylation activity, potassium content, camp release in three days old mycelium of mutants when compared to the cultivation without kk. on the contrary, there is a significant suppression of ergosterol leve ...19947778499

possible role of calcium in phospholipid synthesis of microsporum gypseum.the effect of calcium on lipid synthesis in microsporum gypseum was examined by growing these cells in calcium supplemented (1 mm to 10 mm) medium. maximum incorporation of [14c]acetate into total lipids and phospholipids was observed in cells grown with 6 mm calcium. this was probably due to a 3-fold increase in total calcium levels as incorporation of label was inhibited in total lipids (33%) and phospholipids (20.5%) in calcium-grown cells which were preincubated with the calcium specific che ...19947811720

polymerase chain reaction-based detection of dermatophyte dna with a fungus-specific primer system.there is significant clinical interest in primers which are specific for fungi and do not hybridize to dna of other eukaryotes or prokaryotes. such primers would allow specific amplification of fungal dna from human tissue samples containing fungi. fungal identification to the species level could follow by direct sequencing or restriction analysis. several previously described primer systems cross-react with dna of plants and animals. we have designed a primer system that amplifies a fragment of ...19947845424

antifungal activities of crude extracts of mitracarpus villosus (rubiaceae).extracts of mitracarpus villosus leaves and inflorescences were investigated individually for in vitro antifungal activities by agar-diffusion and tube-dilution techniques. ethanolic extracts produced definite antifungal activities against trichophyton rubrum, microsporum gypseum, candida albicans, aspergillus niger and fusarium solani. the aqueous extracts and the glycerol vehicle control did not inhibit any of the fungi tested. the zones of inhibition produced by the ethanol extracts ranged fr ...19938133654

[incidence of various etiologic agents of superficial mycosis].in a retrospective review of laboratory records at the department of mycology, national institute of microbiology "dr. carlos g. malbrán", during the period june 1989-july 1991, 1225 putatively immunocompetent cases of superficial mycoses were identified. ninety five percent of these patients were adults and 5% children. among the total cases, dermatomycoses were caused, 67.6% by dermatophytes, 25.9% by yeasts, 5.9% by malassezia furfur. and 0.5% by other fungi, as proven by the isolation of the ...19938140245
