Lumpy Jaw, also known as actinomycosis, is a bacterial infection that primarily affects the jaw and face of animals, particularly cattle. It is caused by the bacterium Actinomyces bovis, which can enter through wounds in the mouth or gums. The infection leads to the formation of painful lumps or abscesses, which can disrupt normal feeding and cause significant discomfort. In addition to affecting livestock, Lumpy Jaw can also occur in humans, although it is rare. Treatment typically involves antibiotics and, in some cases, surgical intervention to remove affected tissue. Early detection and management are crucial to prevent complications and ensure recovery.
