Abstract
Strains of M. mycoides ssp. mycoides were divided into small colony (SC) and large colony (LC) types. The protein patterns of representative strains of these 2 types and of M. mycoides ssp. capri were compared by a high resolution, 2-dimensional gel electrophoretic method. The LC strains are more closely related to M. mycoides ssp. capri than to the SC strains of M. mycoides ssp. mycoides.
