Observations on three outbreaks of Leptospira interrogans serovar pomona infection in lambs.

Sickness and deaths associated with leptospirosis were reported in three lamb flocks in the Manawatu region. The clinical, pathological and serological features of Leptospiru interrogans serovar pomona infection are described. The mucous membranes of affected animals were pale and jaundiced. Haemoglobinuria, haemoglobinaemia and centrilobular hepatocellular necrosis were also consistent findings. All clinically sick lambs had very high titres in the microscopic agglutination test for L. pomona. Circumstantial evidence of pigs being the source of infection was found in one of the three cases.

Tuberculosis in a free-living brown hare (Lepus europaeus occidentalis).

A free-living brown hare (Lepus europaeus occidentalis) trapped during a survey of tuberculous possums in the Ahaura Valley, Westland, was found to have both microbiological and histopathological evidence of infection with Mycobacterium bovis. The mesenteric lymph nodes were enlarged and showed extensive caseation, tuberculous nodules were present in the liver and kidney, and there was a proliferative pleurisy. Histologically, characteristic tuberculous granulomatous foci were seen in the mesenteric lymph nodes, liver, kidney, pleura and lungs, often in association with small numbers of acid-fast organisms. This is the first report of naturally occurring tuberculosis due to M. bovis in the brown hare.

Mammary adenocarcinoma and granulosa cell tumour in an aged Toggenberg goat.

An adenocarcinoma of the mammary gland was diagnosed in an aged goat with suspected chronic mastitis. On cross-sectioning, the tumour had a lobulated appearance and contained areas of calcification. Histologically, it was multicentric, exhibiting various growth patterns, including comedo, papillary and solid. There was no evidence of metastasis to the regional lymph nodes. A well-differentiated granulosa cell tumour of the right ovary was also present.

Salivary gland necrosis in a wire-haired fox terrier.

A 2%year-old wire-haired fox terrier had a 2-month history of inappetance, gagging, retching, regurgitation and vomiting associated with bilateral necrosis of the mandibular salivary glands. Surgical removal of the glands did not greatly improve the demeanor of the dog, or alleviate the regurgitation and vomiting. Euthanasia was recommended because of the failure to respond to supportive therapy. The affected glands were enlarged and showed infarction with peripheral reactive inflammation. Compensatory hypertrophy and hyperplasia of the parotid salivary glands were the only other significant pathological findings. No explanation for the vomiting could be found.
