Clostridial diseases (including but not limited to Tetanus, Pulpy Kidney, Blackleg, Malignant Oedema & Black disease) are caused by anaerobic bacteria that are common and widespread in the environment, particularly in soil.

The bacteria produce spores that can survive in the environment for a very long time.

The disease-causing bacteria may be picked up at any time by susceptible animals through either wound contamination or ingestion.

Clostridial diseases strike rapidly and are almost always fatal. Very rarely are clinical signs seen, with infected animals presenting as “found dead”.

Risk factors are a mixture of animal and environmental factors:

• Animal: reduced immunity, injury and wound infection, liver damage, young stock or rapidly growing stock

• Environmental: highly digestible feed, increased exposure to soil in the diet

Vaccination is one viable means of control.
