[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
influence of cyclic amp on the biosynthesis of phosphatidylcholine in microsporum gypseum.the influence of intracellular camp on phosphatidylcholine biosynthesis in microsporum gypseum has been examined using radiolabelled precursors. the incorporation of labelled choline, methionine and ethanolamine into total lipids, phospholipids and choline containing phospholipids increased in aminophylline and decreased in atropine grown cells as a result of rise and fall in camp levels in these cells. the enhanced uptake of labelled methionine and ethanolamine in comparison to labelled choline ...19938144178
