Comparative studies on the growth products of C. ovis isolated from sheep, cow, buffaloes, goat and (C.V.T) strains were carried out. From the results obtained it was noted that maximum produ cts were obtained after 3 days in case of C.V.T. and sheep strains, 5 days in case of buffaloes and goats strains and 7 days in case of cow strain. Electrophoretic separation of extrace llular products was also performed and eluted portions of each of the produced bands were tested for different activities. It was noted that one of the bands showed no activity while other bands may only produce dermo-necrotic activity (D.N.A) or both D.N.A. and hemolytic activities. C.V.T. loss its lethality as well as its dermo-necrotic and hemolytic activity in compora tive to the other strains.
