Endotoxic activity of rough organisms of Brucella species.
A rough-specific antigen extracted from the rough species Brucella ovis and lipopolysaccharide extracted from smooth Brucella abortus demonstrated equivalent levels of activity in tests for mouse lethality and limulus lysate clotting activity. Acetone-extracted whole cells of B. ovis and of B. canis and of a rough mutant of B; abortus had the same toxicity for mice, but it was not possible to extract endotoxin from B. canis by the methods used.
