Classification of Corynebacterium species from axillary skin by numerical analysis of electrophoretic protein patterns

Abstract

The genus Corynebacterium, defined by the presence of mesodiaminopimelic acid, arabinose and corynomycolic acids in the cell wall, contains a very diverse group of organisms according to the results of numerical analysis of protein patterns; 13 groups were distinguished in this study. Strains isolated from axillary skin and hair included representatives of several groups but many strains were placed in groups 1 and 6A. Neither of these groups contained any reference strains and may constitute hitherto undescribed species. The reference strains of C. diphtheriae formed a coherent group not closely related to any non-pathogenic Corynebacterium species.
