Avian Botulism

Overview

Avian Botulism is a serious and often fatal condition that affects birds, particularly waterfowl and poultry. It is caused by a toxin produced by the bacterium Clostridium botulinum. This condition leads to paralysis and, if untreated, can result in death.

Causes

Avian Botulism is caused by the ingestion of the botulinum toxin. This toxin is often found in decaying organic matter, such as dead animals or rotting vegetation, particularly in warm and stagnant water conditions.

Diagnosis
