Characterization of Corynebacterium group JK by whole-cell protein patterns.

A total of 102 strains received as Corynebacterium 'group JK' were characterized by SDS-PAGE of their whole-cell proteins. Numerical taxonomy based on the protein pattern absorbance profiles indicated that 91 of the strains formed a cluster. Seventy strains isolated in the UK were identified as group JK, indicating the increasing detection of this group as opportunistic pathogens. Fine differences between strain patterns were visible but it was not possible to associate these with any particular clinical source.
