Abstract

Pine, Leo (Duke University, Durham, N. C.) and Robert E. Webster. Conversion in strains of Histoplasma capsulatum. J. Bacteriol. 83:149-157. 1962-Photographs of mycelial elements taken at various time intervals from a single strain of Histoplasma capsulatum have shown the direct conversion of microconidia to yeast cells by polar and nonpolar budding, the formation of yeast cells by budding of hyphal cells, and the probable conversion of hyphal cells to yeast phase by monilial chain formation. In addition, studies of fixed-slide preparations of a second strain have indicated the formation of stalked yeast cells arising in a manner similar to that observed for microconidia formation but, apparently, by-passing the microconidial stage. These observations are discussed briefly in regard to temperature-induced changes in cell-wall synthesis during conversion.

摘要

派恩,利奥(杜克大学,北卡罗来纳州达勒姆)和罗伯特·E·韦伯斯特。荚膜组织胞浆菌菌株的转化。《细菌学杂志》83:149 - 157。1962年——从单一荚膜组织胞浆菌菌株在不同时间间隔拍摄的菌丝体成分照片显示,小分生孢子通过极性和非极性出芽直接转化为酵母细胞,菌丝细胞出芽形成酵母细胞,以及通过念珠状链形成菌丝细胞可能转化为酵母相。此外,对第二个菌株的固定玻片制剂的研究表明,有柄酵母细胞的形成方式与观察到的小分生孢子形成方式相似,但显然绕过了小分生孢子阶段。关于转化过程中温度诱导的细胞壁合成变化,对这些观察结果进行了简要讨论。
