Two major subspecies of , namely subsp. , from humans, and subsp. , from humans and other primates, are described on the basis of a study of 14 to 25 strains and 18 to 33 strains, respectively. DNA-DNA hybridization studies conducted in our laboratory in 1983 (W. E. Kloos and J. F. Wolfshohl, Curr. Microbiol. 8:115-121, 1983) demonstrated that strains representing the different subspecies were significantly divergent. subsp. can be distinguished from subsp. on the basis of its greater colony size; pigmentation; positive urease, β-glucuronidase, and β-galactosidase activities; delayed alkaline phosphatase activity; ability to produce acid aerobically from α-lactose; and fatty acid profile. The type strain of subsp. is ATCC 29974, the designated type strain of Schleifer and Kloos 1975b, 55. The type strain of subsp. is ATCC 49330.
