Bronchiolar adenocarcinoma in a cow.

An aged beef cow had a primary lung tumor that was diagnosed postmortem. Clinical signs included inappetence, weight loss, coughing, dyspnea, and reduced lung sounds. Antibiotic treatment was ineffective. The cow was euthanatized. Postmortem examination revealed numerous, firm nodules throughout both lungs. Microscopically, the pulmonary nodules contained neoplastic cells and the diagnosis was bronchiolar adenocarcinoma. A diagnosis of pulmonary neoplasia, although rare, should be considered in an aged cow with similar historical and clinical findings.

Ventricular septal defects in two goats.

Two young goats with loud, holosystolic heart murmurs heard best over the left and right heart base were suspected to have interventricular septal defects. Cardiac catheterization with angiocardiography supported the clinical diagnosis in both goats and the ventricular septal defects were confirmed at necropsy. In one goat a ventricular septal defect was associated with a hypoplastic aorta and in the other, an ectopic ureter opened into the vagina.

Ventricular septal defects in the horse.

Clinical, echocardiographic, and right-side cardiac catheterization data were collected in 6 horses with ventricular septal defects. The defects were confirmed by necropsy in 5 horses. On echocardiography, the cardiac dimensions were normal in 3 horses and enlarged in 2 others. A step-up in partial oxygen pressure between right atrium and right ventricle suggested a left-to-right shunt in 3 of the 4 horses catheterized. In 1 foal, a small defect without PO2 step-up was documented by angiocardiography. The oxymetry and pressure data were compared with previous cases from the reviewed literature, and the importance of pressure measurements to rule out concomitant defects was emphasized.

Study of agglutinins to Brucella abortus, B canis and Actinobacillus equuli in horses.

Horses at a veterinary teaching hospital and a slaughterhouse were surveyed for antibodies to Brucella abortus, B canis and Actinobacillus equuli. Four of the 141 hospitalised horses and none of the 73 slaughtered horses had titres of 1:100 or greater to B abortus. Six horses of both populations reacted to the card test. One was culture positive. A card test using B canis antigen was positive in 38 per cent of the sera from hospitalised horses and all of the slaughtered horses. Twenty (27.4 per cent) of the latter group had high tires in a tube agglutination test. High titres could not be reduced by 2-mercaptoethanol serum treatment. The titres appeared to be associated with advanced age but not to sex. Adsorption of sera with B canis did not affect titres to A equuli but the reverse was true.

Ataxia and paresis with equine herpesvirus type 1 infection in a herd of riding school horses.

An outbreak of neurologic disease associated with serologic evidence of equine herpesvirus type 1 (EHV-1) infection occurred in a herd of 46 riding school horses. Ataxia and paresis were observed in 14 geldings and 5 barren mares. Eight affected horses had distal limb edema, 1 horse had a head tilt, and 3 others had urinary incontinence. Other clinical signs included fever, depression, and inappetance in 30 horses. Seven horses with neurologic signs were treated with acyclovir. Serum neutralizing antibody titers against EHV-1 increased 4-fold between acute and convalescent samples or exceeded 1:256 in 19 of 44 horses, confirming recent infection. A significantly greater proportion of horses that seroconverted were mares (P = .014). Of the 19 horses exhibiting ataxia and paresis, 17 made a complete recovery, 1 made a partial recovery, and 1 was euthanized.
