Abstract
Thirty-six strains of enterococci were examined by standard physiological tests. The soluble proteins of cell-free extracts were separated by electrophoresis in starch gels. Specific staining techniques for glucose-6 phosphate dehydrogenase and glyceraldehyde-3-phosphate dehydrogenase were applied to the gels. The results of electrophoresis supported the subdivision of the group into 2 major divisions represented by S. faecalis and S. faecium with S. durans as a variant of S. faecium. It was possible to tentatively identify 3 strains which did not fit well into the taxonomic scheme used.[long dash]Authors.
