Production of capsule and conidia by yeast-like cells of Phialophora spinifera and Phialophora jeanselmei

摘要: Five strains of Phialophora spinifera Nielsen & Conant 1968 isolated from natural sources as well the original culture Conant, produced on Czapek-Dox's sodium nitrate sucrose agar, single and multiple budding yeast-like cells mostly with a typical capsule. The capsulated non-capsulated before 48 h at 28°C, usually small protuberance, successive elements showing shape size conidia species. Similar features were observed in human strain P. jeanselmei by Murray, Dunkerley Hughes. This converted later into filamentous variant unable to produce capsultaed cells. Two old jeanselmei, Langeron's Emmons's strains, showed only this form growth.
