[Fibrous suppurative arthritis in sheep].

Described are cases of fibrinous supprative arthritis in sheep characterized by thickenning of the joint, resulting from the involvement of the capsule (periarthritis). Histopathologically, there have been suppurative and necrotic processes combined with fibrinoid necrotizing of the collagen fibers and leukocyte infiltration of the joint capsule. Slight leukocyte infiltration has also been said to occur in the parenchymal organs. Microbiologic studies have revealed the presence of pyogenous bacteria (Corynebacterium pyogenes, Streptococcus pyogenes, Pasteurella multocida).
