Abstract
Forty-nine strains of the gliding prokaryote Simonsiella were isolated from the oral cavities of cats (8), dogs (19), sheep (4), and humans (18) in Southern California by a direct isolation procedure using a complex serum-enriched medium. The numerical taxonomic analysis (unweighted pair-group method using arithmetic averages) of 57 differential traits for each strain was based on standard bacteriological diagnostic tests and included the molar guanine-pluscytosine contents of the DNA and the relative percentages of fatty acid contents reported earlier. The resulting phenogram clustered the strains of Simonsiella into groups that correlated with sources of origin. The study included the neotype strain of Simonsiella crassa (ATCC 27504, ICPB 3651, NCTC 10283) of Australian sheep origin. The strains isolated from dogs, sheep, and humans form clusters of organisms that appear to have become adapted to live in and possibly to have evolved with their respective “hosts”. In our judgment, these source-of-origin clusters represent different “ecospecies”.Keywords
