Disseminated hexamitiasis in Siamese fighting fish.

One hundred forty Siamese fighting fish became inappetent and lethargic and developed swollen abdomens. One hundred fish died, many with perforated stomachs. Hexamitid parasites were found in large numbers in the abdominal cavity and in the mesentery and the parenchyma of the liver, spleen, and kidney, where they were closely associated with a chronic inflammatory response. Species of bacteria recovered from the peritoneal cavity were believed to be secondary invaders. The 40 surviving fish, including some sick ones, were treated with nifurpirinol at the rate of 0.2 mg/L and 5 mg/kg of body weight, by means of a bath and a feed medication, respectively. The sick fish recovered, and no more died.

Dysentery in pigs associated with cystic enlargement of submucosal glands in the large intestine.

Grossly visible glands were found in the submucosa of the large intestine of five pigs with dysentery. Some were cystic, some were filled with necrotic debris and some had perforated the serosal surface. The mucosa of the large intestine of all pigs had areas of acute catarrhal inflammation with haemorrhage and focal sloughing of the surface epithelium. Although very distinctive and analogous in most respects to collitis cystica profunda, it was felt that the cystic and hypertrophic glands were a secondary finding and represented involvement of glandular elements present in normal animals. Anaerobic vibrio were recovered from three pigs, but the significance of these isolates is unknown.

Toxoplasmosis in a calf.

Gross post mortem and histopathological changes are described in a calf with toxoplasmosis. The major pathological changes were restricted to the lungs and kidneys and comprised interstitial pneumonia with multifocal necrosis, and glomerular necrosis. Many pseudocysts were present in both organs. The calf had been in close contact with young cats, one of which was killed and examined and shown to have a high antibody titre to Toxoplasma gondii, although there was little histological evidence of infection. No antibodies to toxoplasma were detected in serum from the dam of the calf, and accordingly, it is suggested that the cat was the source of infection for the calf.

Antibodies to Leptospira in the sera of aborted bovine fetuses.

Antibodies to Leptospira serotypes were detected in sera from 15 (6.9 per cent) of 218 aborted fetuses, but were not detected in the sera from 196 non-aborted fetuses. Fourteen (6.4 per cent) sera from the aborted fetuses had antibodies to strains belonging to the Hebdomadis serogroup and 1 (0.5 per cent) had antibodies to a strain belonging to the Icterohaemorrhagiae serogroup. These antibodies were predominantly immunoglobulin M whereas in the dams, antibodies belonged to both immunoglobulin M and G classes.
