Description    Abscesses are common in goats and sheep. Usually due to the pleomorphic, facultative intracellular, Gram-positive rod CORYNEBACTERIUM PSEUDOTUBERCULOSIS (Caseous Lymphadenitis) but other organisms might be isolated such as ACTINOMYCES in goats. Lesions might be found in various parts of the body following spread from skin or lung abscesses; if the udder is invaded there can be mastitis. Visceral abscesses can cause wasting.
