Abstract
Clostridium perfringens, a spore-forming, Gram-positive, anaerobic bacterium, causes a variety of diseases throughout the animal kingdom. Each disease in each animal species tends to be caused by particular strains of C. perfringens and is defined by the tissue tropism and toxin profile of the bacteria. In chickens toxinotype A strains cause necrotic enteritis; a disease characterised by tissue damage to the proximal regions of the small intestine. In extreme cases the disease can be lethal but is more commonly seen as a sub-clinical disease that causes welfare issues and productivity losses within the poultry industry. The disease is currently well controlled in Australia by good management practices and, for some poultry producers, the use of antibiotics in the feed. However, the disease does cause significant issues in other regions including North America and Europe. In Europe there was a spike of necrotic enteritis disease when antibiotics were withdrawn from animal feeds. It is probable that the disease will become more of an issue in the Australian poultry industry as in-feed antibiotic use is reduced. Therefore, other methods of disease control are under investigation, including the development of vaccines.
