Combinations of romifidine and butorphanol were used to sedate 55 horses for a variety of surgical, therapeutic and diagnostic procedures. Eighteen of the horses were given the drugs separately, romifidine first followed by butorphanol four minutes later, and 37 were given the drugs together. The levels of sedation and ataxia were assessed and graded, and there were no statistically significant differences between the two methods of administration. The side effects were typical of the alpha-2 agonists, including bradycardia, heart block and some sweating. Box-walking was observed in one horse. The procedure attempted was successfully completed in 54 of the horses, and the combination of drugs was judged to be a safe and effective sedative for horses.

Romifidine, 100 micrograms/kg administered by intravenous injection, was evaluated as a premedicant to ketamine/halothane anaesthesia in 60 horses. Sedation developed within one to two minutes. In three cases mild staggering occurred within two minutes. Anaesthesia was induced after five minutes by the intravenous administration of ketamine (2 to 2.2 mg/kg). A mean time of 79 seconds elapsed before lateral recumbency was adopted. Fifty-four of the horses sank smoothly to the floor, with occasional steps sideways. Jaw tone, limb rigidity and mild muscle tremors often persisted for short periods after induction. Complete relaxation was achieved on average two minutes after the administration of ketamine. The transition to oxygen/halothane anaesthesia was excellent or good in 53 cases. The mean duration of anaesthesia was 79 minutes. Forty-seven of the horses were able to stand after one or two attempts with little or no ataxia. After halothane administration ceased, the mean time to sternal recumbency was 25 minutes and the mean time to standing was 33 minutes. Most horses appeared to be sedated upon standing, but they were able to walk soon after regaining their feet. The characteristics of the induction of anaesthesia were similar to those seen when detomidine/ketamine or xylazine/ketamine are used. The maintenance of anaesthesia with halothane was similar to that following other induction protocols, and the recovery from anaesthesia was smooth and free from excitement.

A lakeland terrier puppy had progressive hindlimb ataxia associated with pain in the thoracic spine. Plain radiographs revealed a lesion affecting the dorsal neural arch of the fourth thoracic vertebra and myelography revealed compression of the spinal cord associated with the lesion. Surgical excision of the mass cured the dog's clinical signs. A histopathological examination of the excised tissue supported a diagnosis of osteochondromatosis.

Lasalocid sodium was accidentally introduced into the feed of several broiler breeder chicken farms at levels between 115 and 150 ppm. On one farm, leg weakness and ataxia were observed in a few cockerels. A reduction in egg production and a sharp decrease in fertility and hatchability were observed in all the flocks receiving the contaminated feed. Many piping chicks were unable to hatch and there was an increase in the number of weak ataxic chicks at the hatchery. Histological examination of the muscle tissues of the affected cockerels, the piping chicks unable to hatch and the one-day-old chicks with leg weakness and ataxia revealed severe muscle damage. Increasing levels of lasalocid were detected in the yolk of eggs collected from the affected flocks.

The history, clinical signs and radiographic and ultrasonographic findings in 16 dogs with pancreatic neoplasia were reviewed retrospectively. Thirteen of the dogs had islet cell carcinoma compatible with insulinoma, one had a pancreatic adenocarcinoma and two had secondary invasion of the pancreas, one by a gastric carcinoma and one by an intestinal lymphoma. The clinical signs in the 13 dogs with insulinoma included collapse in 10 dogs, ataxia in seven, weakness in five, and seizures in two. Two of the 16 dogs had jaundice due to biliary obstruction by the primary tumour or metastases. The sensitivities for pancreatic neoplasia were three of 16 (19 per cent) for radiography and 12 of 16 (75 per cent) for ultrasonography; the sensitivities for metastasis were two of 11 (18 per cent) for radiography and six of 11 (55 per cent) for ultrasonography. Biliary obstruction was detected by ultrasonography in both affected dogs.

Thirteen cases of a disease with a low morbidity and very high mortality in horses in Nigeria are described; the disease is characterised by fever (rectal temperature > or = 40 degrees C), generalised muscle spasms, ataxia, increased respiratory and heart rates and terminal lateral recumbency. The illness generally lasts three to five days but durations of 12 to 30 hours have been observed. Laboratory investigations, including histopathology and serology suggest a viral aetiology, possibly an alphavirus of the equine encephalitis group.

Twenty-seven cases of neosporosis in European dogs are described. The disease was confirmed by immunohistochemistry, electron microscopy, or a favourable response to treatment in the dogs with appropriate clinical signs, and by the presence of antibodies to Neospora caninum but not to Toxoplasma gondii. The affected dogs were two days to seven years old, and of 13 different breeds. Both sexes were affected and in most cases littermates remained normal. Twenty-one cases had an initial hindlimb paresis or ataxia, in which muscle atrophy was the most consistent clinical sign. Rigid hyperextension developed in approximately half of the cases. Anorexia and pyrexia were rare. Other clinical signs included forelimb ataxia, head tremors with tetraparesis and sudden collapse due to myocarditis. Titres of > or = 1:800 in the N caninum indirect fluorescent antibody test were detected in the 20 cases from which serum samples were taken. Such high titres are rare in healthy dogs and strongly suggest a diagnosis of neosporosis. Sixteen of the dogs received appropriate antiprotozoal treatment with clindamycin, potentiated sulphonamides and/or pyrimethamine; 10 made a full or functional recovery. Recovery was less likely in peracute cases with severe clinical signs, and when the treatment was delayed.

A case of poor condition and recumbency in a 14-month-old female llama and a case of poor condition and ataxia in a 23-month-old male llama are described. Both animals were anaemic and had low plasma copper levels. An increased intake of feed with a higher copper level and treatment with copper injections and an oral mineral solution resulted in a successful recovery. Two other young llamas also had low plasma copper levels. The problem was probably due to a nutritional, particularly copper, deficiency and the animals recovered as their copper levels increased.

A total of 42 birds from a flock of 104 farmed ostriches showed signs of toxicity after the accidental inclusion of monensin in their concentrate ration. The initial clinical signs were muscle weakness and ataxia which progressed to recumbency, dyspnoea and death, despite intensive supportive therapy. The serum activity of the enzymes creatine kinase, aspartate aminotransferase and lactate dehydrogenase was high in the affected birds, indicating significant muscle pathology. Few gross lesions were identifiable postmortem, but widespread lesions of degenerative myopathy were present at the histopathological level. However, these degenerative changes were restricted to the skeletal muscle and there was no evidence of cardiomyopathy in any of the birds examined. The birds were fed a ration which contained 215 to 224 ppm monensin for 13 days. New clinical cases ceased to occur shortly after the withdrawal of the source of monensin, but all the individuals which showed clinical signs of toxicity died or were euthanased on humane grounds.

Four rottweiler pups from two litters developed severe progressive signs of spinal ataxia, cerebellar ataxia and tetraparesis/paralysis. The signs started with ataxia of the pelvic limbs at seven to eight weeks of age and progressed to tetraparesis and paralysis within three to five weeks. Postmortem, a vacuolar neuronal disorder was found in the cerebellum, brainstem and the spinal cord, associated with Wallerian type degeneration in the brainstem, cerebellar peduncles and the medullary cord. Electron microscopy revealed empty membrane-bound vacuoles. Immunohistochemistry for PrPSc was negative. The disorder differs clinically and pathologically from other neurological disorders in the breed and a new (familial) neurological disorder in the rottweiler is suspected.
