Yep, that's tetanus. In fact, all those are Clostridials...perhaps a bit confusing on Jeffers's part....is "tetani"...tetnus??
From Jeffers:
Clostridium Chauvoei, Septicum Haemolyticum, Novyi, Tetani, Perfringens Types C & D Bacterin-Toxoid
(Schering-Plough) For vaccination of healthy sheep and cattle.
Could have read:
Clostridium Chauvoei, Clostridium Septicum, Clostridium Haemolyticum......etc.
Just out of curiosity...on the weeping ooziness...are you perhaps using a bottle that was drawn out of before, then put back in the fridge? I only ask because I've seen half-used bottles of biologicals in folks' med fridges before, even though all those bottles basically say pitch it after first use.
