Concurrent maedi-visna virus infection and pulmonary adenomatosis in a commercial breeding flock in East Anglia.

The seroprevalence of maedi-visna virus infection in thin potential cull ewes aged over two years in a flock in East Anglia increased from 3.7 per cent in August 1985 to 39.0 per cent in September 1987 and 93.3 per cent in May 1989. This increase coincided with the first appearance of sheep pulmonary adenomatosis in the flock. Four emaciated ewes which were dyspnoeic were necropsied between 1987 and 1989. Maedi and pulmonary adenomatosis were confirmed histologically in one of these ewes and pulmonary adenomatosis was confirmed in the other three.

Spastic syndrome in a Holstein bull: a histologic study.

A 4-year-old Canadian holstein bull developed the spastic syndrome, an episodic but progressive disorder causing pelvic limb muscular spasms. A post-mortem study, including morphometry of skeletal muscles and teased peripheral nerve fibers of the pelvic limb, revealed mild type II skeletal muscle fiber atrophy and minimal, focal segmental demyelination with remyelination, and axonal degeneration in peripheral nerves. Such alterations are probably incidental or age-associated. Idiopathic muscular cramps is the most probable explanation of the clinical disease and is consistent with the absence of significant morphologic pathologic lesions.

Detachment of the ischial tuberosity sows.

The clinical and pathological features of five cases of detachment of the ischial tuberosity are described. In two cases, the detachment occurred unilaterally; one was a gilt showing severe lameness which precluded mating and the other was a uniparous sow which showed only slight lameness. Three gilts which were affected bilaterally developed progressive lameness during pregnancy and were unable to stand after farrowing. One of these gilts died and two had to be slaughtered. The diagnostic features of the epiphyseal detachment were shortening of the caudal extremity of the ischium, palpation of the displaced ischial tuberosity and crepitation elicited by pressing the displace tuberosity against the ischium.

Solanum malacoxylon poisoning in pigs.

Solanum malacoxylon was given orally to four pigs. The animals were examined clinically and subjected to post mortem examination. Macroscopic lesions were not seen with the exception of a small calcified plaque in the endocardium of one animal. Microscopic examinations revealed slight calcification of elastic fibres in the soft tissues. The pathological changes in the bones were extensive and are described in detail. The pigs showed minimal lesions at dose levels which cause considerable systemic calcification in cattle and sheep.

Hemivertebra in the dog: clinical and pathological observations.

The clinical and radiographic findings associated with the presence of hemivertebra ("wedge-shaped"vertebra) in small and brachycephalic breeds of dogs are reported together with the results of post mortem examination in the availabel cases. The condition is characterised clinically by progressive hind-leg weakness, spinal pain, abnormalities of the nervous system and evidence of muscle atrophy or other abnormalities of conformation. Confirmation of the clinical diagnosis is by radiography. It is suggested that the condition is congenital in origin. Breed incidences are reported. The occurrence of the disorder in certain families of dogs suggests also that it may be hereditary. Other congenital abnormalities are seen in some dogs affected by hemivertebrae.
