Size of the Spores of Histoplasma capsulatum.

Abstract

Summary

1. In an effort to determine the size of the spores in Histoplasma capsulatum, 1000 spores from each of 5 strains were measured. To obtain a homogeneous suspension the entire culture was scraped from the potato dextrose agar slant and macerated in a sterile glass tissue grinder. The measurements were made using a high power oil of immersion lens. 2. On the whole, our results confirm those reported by Cozad and Furcolow and substantiate the high frequency of small spores in the strains of Histoplasma capsulatum observed.
