Outline Classification of Bacterium and Staphylococcus

Abstract

SUMMARY: The National Collection of Type Cultures, in its list of species maintained, uses unorthodox classifications of the genera Bacterium and Staphylococcus. For convenience in cataloguing Bacterium is divided into groups representing coliforms, plant pathogens, non-fermenting species and paracolons; to these is added a miscellaneous group of organisms of uncertain taxonomic position. These subdivisions are not intended to constitute a valid classification. Coagulase-positive staphylococci, irrespective of pigment, form the species pyogenes; coagulase-negative strains are subdivided according to the pigment produced.
