Caseous lymphadenitis was the most frequently encountered pathological condition in 3,720 feral goats examined during routine meat inspection procedures. Among 9 separate consignments of animals, the prevalence of infection averaged 7.4% (range 0.3% to 18.8%). The majority of lesions were seen in lymph nodes draining superficial body areas although many also occurred in internal nodes and organs. Corynebacterium ovis was isolated from 25 of 32 lesions submitted for bacteriological examination. Other conditions regularly encountered included pneumonia, cysticercosis, sarcosporidiosis and lice infestation, while myonecrosis, pleurisy, pericarditis, nephritis, hepatitis, cirrhosis and mite infestation were only occasionally found. A total of 171 serum samples were collected and tested against 17 antigens. Samples from 57.9% and 51.5% of goats showed positive serological reactions to the antigens for sarcosporidiosis and Q fever respectively.

Between 1978 and 1981, 20 platypus (Ornithorhynchus anatinus) which had been held in exhibits for varying periods, were submitted for necropsy. The most common gross and histologic lesions were adrenal enlargement, pulmonary pathology consistent with shock or aspiration pneumonia, intestinal coccidiosis, the presence of trypanosomes, myocarditis and nephritis. Other conditions encountered included infestation with ticks (Ixodes ornithorhynchi), a mild infection of intestinal trematodes (Mehlisia ornithorhynchi), myocardial toxoplasmosis, and focal hepatic necrosis. Adrenal weights, both absolue and relative to body weight, were determined in 12 specimens, and used as parameters of each animal's response to the stress associated with captivity. The results showed that, in platypus held in captivity from about 1 day up to 6 mo, both parameters were higher than in animals which were examined within a few hr of capture. In view of the general lack of conclusive necropsy findings, it was considered that these results indicated that stress may have been a significant underlying factor in the death of these animals in captivity.

Histological investigations were made over a 10-year period on 164 lesser mouse lemurs that died spontaneously in captivity. The principal lesions found were chronic nephrosis with nephritis which affects 90% of the animals, myocardial necrosis, respiratory insufficiency induced by interstitial pneumonia, fatty changes in the liver, and splenic and gastric lesions. The following are associated with these pathologies: progressive hypothyroidism, stable hypercorticism, slight medulloadrenal hyperactivity, and sexual disorders such as testicular atrophy in males and estrous cycle disturbance or uterine tumor in females. All these data were treated by correspondence analysis; this showed that, except for some rare cases of death which can be attributed to massive parasitic infestation or generalized cancer, the whole captive population of lesser mouse lemurs is suffering from a syndrome that leads to renal insufficiency and death. Most of the observed pathologies are considered as being associated with aging in mammals. But captive Microcebus murinus died between 3 and 4 years of age, whereas their potential life survival is 13 years. Our hypothesis is that these pathologies arise due to an overload of cortico- and medulloadrenal secretions. The above-mentioned hormonal imbalance could be induced by stress factors occurring in captivity, the most important of which would be social stress.

A two-year-old Swiss Braunvieh cow was referred to our clinic because of tenesmus and weight loss. Clinical examination revealed a moderately abnormal general behaviour and condition, thin body condition and a rectal temperature of 40.1 degrees C. Tenesmus was evident, and rumen and intestinal motility were markedly reduced. All tests for a reticular foreign body were positive. On rectal examination, a round, smooth, firm, non-painful mass with a diameter of approximately 15 cm was palpated far cranially on the right side. Abnormal haematological and biochemical findings included marked anaemia, neutrophilic leucocytosis, markedly elevated concentration of fibrinogen and mildly elevated gamma-glutamyl-transferase activity. The clotting time of the glutaraldehyde test was one minute. Ultrasonographic examination revealed abscesses involving the liver and extending caudally into the right flank region. The liver parenchyma had diffuse changes. Because of a grave prognosis, the cow was euthanized. Postmortem findings substantiated ultrasonographic results; there were abscesses, caused by Fasciola hepatica infestation, originating in the liver and extending into the right flank. As well, there was severe, bilateral, multifocal, suppurative nephritis due to thromboembolism. Based on all the findings, a diagnosis of liver abscess caused by fascioliasis and bilateral suppurative nephritis was made.
