Acute posterior paralysis in two weaner pigs was attributed to ischemic infarction of the lumbar spinal cord due to fibrocartilaginous emboli. These arterial and venous emboli were assumed to have originated from the nucleus pulposus of one or more intervertebral discs. There was no indication of an initiating factor in either instance, although some form(More)
Navicular bones from 74 horses were examined at necropsy. Animals ranged in age from eight months to 30 years. Eight horses had a clinical history of navicular disease. Degenerative lesions in the fibrocartilaginous surface of the navicular bone and of the surface of the deep flexor tendons were age related changes not necessarily related to lameness. These(More)
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)
Fifty-two joints from pigs with nonsuppurative joint disease from a local abattoir were examined grossly, histologically, and microbiologically in order to establish macroscopic differences between degenerative arthropathy and arthritis due to an infectious organism. The joints were grouped grossly according to the type and severity of lesions of the(More)
The potential involvement of the pharyngeal tonsil in the pathogenesis of bovine herpesvirus-1 (BHV-1) infection was examined in neonatal and weanling calves infected by intranasal aerosol. Calves were monitored from days 1 to 5, and on day 6 (neonates) or 8 (weanlings) and, in a second trial at day 4.5, by histology, electron microscopy,(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)
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)

Gross and microscopic lesions of discospondylitis in swine are described. Gross lesions were characterized by areas of destruction and cavitation involving intervertebral discs and adjacent structures. Microscopically, acute lesions had hemorrhage and necrosis with infiltration of granulocytes and mononuclear cells. In chronic cases intradiscal structures(More)
