Clostridium Organism Transmission

The bacteria that causes Blackleg illness lives in the intestines of animals and may persist in soil for many years. Contaminated pasture is thought to be the cause of the virus, which is likely swallowed by the animal and spreads to other tissues through circulation.

The Spread of Blackleg

The bacteria Clostridium causes Blackleg and may be detected in the spleen, liver, and digestive system of animals. Although the actual origin of bacteria spreading in muscle tissues is unknown, physical stress during transportation, herding, and handling is thought to generate circumstances conducive to bacterial development and tissue injury.
