Actinomyces bovis is a type of bacteria that primarily affects cattle, causing a disease known as actinomycosis or lumpy jaw. This bacterium is part of the normal flora in the mouths of animals but can become pathogenic when it enters tissues through wounds or abrasions. The infection leads to the formation of abscesses in the jaw and other areas, resulting in swelling and pain. Treatment typically involves antibiotics and, in some cases, surgical intervention to remove affected tissue. Early detection is crucial for effective management of the disease in affected animals.
