[QUOTE="simme, post: 1685122, member: 40418"] From an Alabama Extension website: "What we commonly call blackleg is a highly fatal infection caused by Clostridium chauvoei, resulting in a gas gangrene in the muscle of young cattle, usually occurring between 4 months and 2 years of age. Blackleg seldom affects cattle older than 2 years of age, most likely due to immunity induced by vaccines or natural exposure. However, sporadic cases do occur in cattle older than 2 years and are often associated with the reuse of needles for multiple injections. [B]Blackleg can also be a problem in cattle less than 4 months old that do not receive adequate passive immunity through colostrum[/B]. Some of the other clostridial diseases are not as restricted to younger animals as is seen with blackleg." "Certain environmental conditions can aid transmission of clostridial bacteria.
