There really isn't a treatment for Blackleg, since it is a highly fatal disease, except for giving the calf massive doses of penicillin or tetracyclines when the disease is in the early stages. This will sometimes help, though most cases the calf perishes anyway, and those calves that do get blackleg will die before you have a chance of knowing that they even got it.
The best thing to do is to have a prevention program against blackleg in your herd. This means vaccinations; the recommendation is to vaccinate all calves that are about 3 to 4 months of age, followed by a second shot or booster vaccination when they are 12 months of age. In endemic areas (or areas where the bacteria Clostridia chauvoei are highly prominent), calves should be vaccinated when they are about 1 month of age. A natural resistance tends to develop when they reach 2 years old.
No. The only way you can "cure" a calf, if the disease is caught in the early stages (which is quite rare) is to inject massive doses of penicillin and tetracyclines into the calf. Other than that the best "cure" is prevention, by vaccinating your herd for blackleg before the disease shows itself.
Vaccination is the best way to prevent blackleg.
A blackleg is a person who takes the place of striking workers, a person who cheats, or a notorious gambler.
Pretty much anything, but the two most likely reasons could be blackleg and scouring. You better get your vet out to do a necropsy on the calf, as if it is blackleg, you better get those calves vaccinated for blackleg ASAP.
Clostridium chauvoei
Nope, it's infectious, but not contagious.

The person is known as a blackleg.
Blackleg. There may also be a bacterial strain of pneumonia that could kill a calf in less than 24 hours, but Blackleg is most likely the prime suspect.
Yes, if there is very little snow cover over the dirt in the dry-lot, and if the winter has been warmer than usual. Also, in areas where snow does not accumulate all that much or not at all, blackleg can be quite prevalent.
Humans do not usually get sick when being accidentally injected with the Blackleg vaccine for animals. These vaccinations only contain the dead virus. It is important to keep an eye on the injection site and to watch for symptoms just as a precaution.
Blackleg, black quarter, quarter evil, quarter ill (Latin:Gangraena emphysematosa) is an infectious bacterial disease of sheep and cattle, caused by Clostridium chauvoei bacteria. It is found all over the world. A symptom of blackleg is characteristic swellings which make a cracking sound under pressure. Blackleg vaccine gives immunity against it.

Clostridium chauvoei is an anaerobic and sporulated bacterium which produces blackleg in cattle, sheep and other ungulates.
