The mechanisms and completeness of equine articular cartilage repair were studied in ten horses over a nine month period. Large (15 mm square) and small (5 mm square) full-thickness lesions were made in weight bearing and nonweight bearing areas of the radiocarpal, middle carpal and femoropatellar joints. The horses were euthanized in groups of two 1, 2.5,(More)
A case-control study was conducted to identify risk factors for the congenital hypothyroidism and dysmaturity syndrome of foals. A questionnaire was used during personal interviews of foal owners and farm managers to collect information on animal signalment, farm environment, and mare management. Information on 39 foals with the congenital hypothyroidism(More)
Nineteen calves with a clinical history of posterior weakness or ataxia were examined at necropsy. Dorsoventral narrowing of the vertebral canal and myelopathy were found in the thoracic and lumbar areas of the spinal cord; vertebral metaphyseal growth plates had focal areas of premature closure. Malformation of the cranial base and hydrocephalus were also(More)
Suppurative cholangitis in 5 aged cats was characterized clinically by weight loss, depression, dehydration, icterus, and fever. The major abnormal laboratory findings were a severe left shift of WBC and a high, conjugated bilirubin concentration consistent with an inflammatory process and cholestasis. Gross pathologic findings included periductal biliary(More)
We describe herein an epidemiological investigation of the cause of a syndrome of congenital spinal stenosis (CSS) in four beef herds in western Canada. Three of the herds were affected with the syndrome in 1987, the fourth was affected in 1990. The prevalence of CSS in affected groups of calves varied from 29% (16/55) to 100% (14/14). All affected calves(More)
Sixteen crossbred Hereford range calves were used to study the effects of Pasteurella haemolytica aerosols of various concentrations administered 4 days after they were exposed to a uniform aerosol of bovine herpesvirus-1 (BHV-1). All calves were given BHV-1 on day 0. On day 4, groups of 4 calves each were exposed to aerosols of P haemolytica generated from(More)
Studies were conducted to determine the effects of delaying the separation of serum from the clot and of long-term storage of serum samples on the measurement of thyroid hormones in blood from horses using a fluorescence polarization immunoassay. The measured concentrations of T3 and T4 were not affected by leaving serum on the clot for as long as 24 hours(More)
