A syndrome of acquired immunodeficiency has been identified in a group of rhesus monkeys (Macaca mulatta) which died at the California Primate Research Center. Clinical evaluation of these animals revealed that 50% or more had lymphadenopathy, weight loss, and diarrhea. At least 30% had splenomegaly, fever, cutaneous abscesses and/or arthritis/myositis. Two animals had fibrosarcomas. Anemia was seen in 19 animals, lymphopenia in 14, granulocytopenia in four and thrombocytopenia in three. Hepatitis was diagnosed histopathologically in 13. Electrophoresis revealed hypoproteinemia, hypoalbuminemia and hypogammaglobulinemia. Numerous bacterial, protozoal, and viral agents were identified including cytomegalovirus and leukocyte-associated herpesvirus. Pathologic lesions included severe post-reactive depletion of lymphocytes in germinal centers and paracortical regions of lymph nodes. Clinical and pathologic changes indicate an acquired immunodeficiency syndrome which has some similarities to AIDS in humans. This disease in monkeys may provide a model for studying that disease.

A 5-year-old Quarter Horse mare was referred for evaluation of oral ulcers, limb edema, weight loss, and weakness. There was marked diffuse swelling extending from the stifle region to the tarsal region of the left hind limb, and the horse had a left hind limb lameness. Firm swellings ranging from 2 to 15 cm in diameter and consisting of nodules, plaques, and discrete masses were palpated on both sides of the neck, over the right shoulder region, over the left elbow region, and over the left caudoventral aspect of the abdomen. Laboratory abnormalities included hypoproteinemia, neutrophilia, and hyperfibrinogenemia. Results of ultrasonographic examination of the left hind limb and masses were suggestive of muscle edema, necrosis, and hemorrhage. Histologic examination of a biopsy specimen from a subcutaneous mass revealed necrotizing, suppurative myositis. The horse's condition gradually deteriorated, and the horse was euthanatized. Necropsy revealed myonecrosis, cutaneous infarcts, hepatic abscesses, and cholangitis. Salmonella serovar Infantum was cultured from liver and muscle lesions, and a diagnosis of Salmonella myonecrosis was made.

A 1.5 year old neutered male pet ferret (Mustela putorius furo) was presented with a sudden onset of severe weakness. The ferret was kept with three healthy mates, was vaccinated against distemper regularly and was never ill before presentation. Clinically, the ferret was depressed, had a hyperthermia of 40.3 degrees C, tachypnea and ocular as well as nasal discharge. Blood work revealed a mild neutropenia, blood chemistry a hyperglycemia, hyperbilirubinemia, hypoproteinemia, hypoalbuminemia, hypocalcemia and hyponatremia. Despite intensive therapy including fluid replacement, antibiosis, analgesia and antipyretics, the overall condition of the ferret deteriorated and the animal was euthanized two days later. Necropsy revealed a pyogranulomatous myositis, fasciitis and steatitis of the long hyoid muscles, the esophagus and intestine. Lesions were consistent with the disseminated idiopathic myositis of ferrets. This is the first reported case of this disease in a ferret originated in Germany.
