Abstract
51 strains grown on a complex agar medium indicated a high degree of heterogeneity in colonial morphology both within and between strains. A strain possessing high virulence for hamsters was almost completely homogeneous, and "typical" colonies of this strain, were buff in color and had a dull, slightly rough surface. Other colonial types designated as "smooth", "intermediate", and "dense, yellow" were isolated from subcultures of this strain. A "wrinkled" variant and several forms of granular and rough colonies were found upon examination of other strains. Incubation led to the establishment of new colonial types in several strains tested, and "wrinkled" and "white, opaque, glistening" colonies were isolated from cultures inoculated with "typical" and "intermediate" forms.
