Note on an association of Clostridium novyi type A and Clostridium sordellii with a case of gas-gangrene in a Zebu cow.

A case of gas-gangrene myositis on a Zebu cow with association of Clostridium novyi type A and Clostridium sordellii is described. The occurrence of both organisms in the same lesion has been rarely reported and differential diagnosis with blackleg is difficult in the absence of bacteriological tests. An iatrogenic cause cannot be overruled as routine mass vaccination against blackleg are practiced in the area with possible introduction of spores through infection material. Full recovery occurred after four days intramuscular Terramycin shot.
