Electron microscopy of the transitional conversion cell of Histoplasma capsulatum.

摘要: Aspects of the fine structure transitional conversion cell formed during early stages yeast to mold morphogenesis ofHistoplasma capsulatum as seen in ultrathin sections are described and illustrated by electron micrographs. Formation was observed occur with highest degree frequency between 18th 24th hr following induction conversional stimulus, although many yeastlike cells were undergo degeneration or initiate only abort process. Cytoplasmic streaming organelle migration from parent prior septation. The wall form is thinner than that appears arise inner portion laminated adjacent plasma membrane converting cell. Interseptal Woronin bodies association septal pore completed septum cytoplasm both presence these structures support strongly pre-hyphal character complex.
