ABSTRACT
Production of CO2, fatty acids and glycerol from glucose and acetate was measured in slices of liver and adipose tissue taken from mature dogs. Acetate was the predominant carbon source for de novo fatty acid synthesis in both tissues. Fatty acid synthesis occurred at greater rates in adipose tissue than in liver. Glucose provided carbon for glycerol synthesis production in adipose tissue. Results support the concept that adipose tissue, and not liver, is the principal anatomical site for fatty acid synthesis in dogs.

Four gray fox became anorectic and developed diarrhea. Their condition worsened until death. Diagnosis of Tyzzer's disease was made on the basis of clinical signs, gross and microscopic lesions, and the demonstration of Bacillus piliformis in the liver.

An acute fatal disease occurred in a mouse colony at the authors' institution. The disease caused 50% mortality among weanling mice, and was characterized clinically by depression, rough hair coat, and distention of the abdomen. The most prominent gross lesions were watery fluid and gas in the small intestine. Numerous organisms identified as Hexamita muris were seen in direct smears of the intestinal fluid. Microscopic and electron microscopic examination revealed the same organisms in the intestinal crypts, within the mucosal epithelium, and in the lamina propria. Treatment with dimetridazole controlled the clinical disease but did not eliminate the infection.

The middle ears of 2001 young and 583 adult rabbits being slaughtered for human consumption were examined. Otitis media was found in 87 (4%) of the young rabbits, and in 188 (32%) of the adult rabbits. The condition was bilateral in 61% of the affected young rabbits and 70% of the affected adults. Pasteurella multocida was isolated from 60 (98%) of 61 affected young rabbits. The gross and microscopic lesions and secondary complications were similar to those described in children. Rupture of the tympanic membrane was observed in both affected young and affected adult rabbits.

A survey of six commercial rabbit colonies was conducted to determine the prevalence of the mite Cheyletiella parasitvorax. This mite was present in all six colonies, and 43.2% of 220 rabbits examined were infested. Listrophorus gibbus, reported only once previously in domestic rabbits in the United States, was found in four of the six colonies, and in 7.3% of the 220 rabbits examined. Non-parasitic mites were found in 3.2% of the samples. Over 50% of the rabbits examined had inapparent mite infestations.

Rabbits were orally infected with Taenia pisiformis eggs and then serially killed. The development and regression of focal granulomatous lesions in the liver were observed, and these lesions were considered to be identical with the lesions in the naturally occurring disease. Focal granulomatous lesions containing onchospheres were also observed in the lungs, mesentery, and mesenteric lymph node. Thrombosis was present in some pulmonary arteries, and infarction of the lung was observed in 1 rabbit.
