What is black quater?

As an AI language model, I assume you are asking about:"black quarter" also known as "Quarter evil" or "Blackleg disease", which is a bacterial infection found in cattle, sheep, and goats, caused by the bacterium, Clostridium chauvoei. It affects the muscle tissue of infected animals, often resulting in sudden death. The bacteria are typically widespread in soil and the intestines of healthy animals, including humans. Vaccination is the primary means of preventing black quarter, and prompt veterinary attention is necessary if an animal is suspected of being infected. Control measures, including proper disposal of infected animals and contaminated materials, are also important in preventing the spread of the disease.
