A new species of , which accounted for 50% or more of the bacterial population in the colons of pigs and was also isolated from pig feces, is described. Isolates of were anaerobic to aerotolerant, nonmotile, nonsporing, gram-positive cocci. All strains were β-hemolytic and hydrolyzed urea. Ammonia did not serve as a sole nitrogen source for , nor did the addition of ammonia to the culture medium affect urease activity. Of 130 strains tested, 29 reacted with rabbit antiserum prepared against Lancefield group G streptococci. The remaining strains did not react with any Lancefield group antiserum. The guanine-plus-cytosine content of the deoxyribonucleic acid ranged from 39 to 40 mol%. A culture of the type strain (strain 76-84-1) has been deposited in the American Type Culture Collection as strain ATCC 43492.
