Progressive ataxia and quadriparesis in two shih tzu littermates was found to be caused by almost identical, cranial cervical, spinal arachnoid cysts. The cysts were treated surgically by dural marsupialization via a dorsal laminectomy. One pup recovered uneventfully and remains clinically normal more than a year after surgery. The second pup made a slow and incomplete recovery before the signs worsened, necessitating euthanasia. Postmortem examination showed no evidence of the re-formation of the cyst.

Twenty-three ewes in a flock of 2000 were identified as having acute onset ataxia and/or having become recumbent in late pregnancy and early lactation. The presence or absence of 15 clinical signs were recorded. Thirteen of the ewes (57 per cent) were hypocalcaemic and 10 (43 per cent) were normocalcaemic. In the hypocalcaemic group, loss of anal reflex, constipation, tachycardia, hyposensitivity, ruminal stasis, ruminal tympany, salivation and tachypnoea were recorded in 50 per cent or more of the cases. In the normocalcaemic group, tachycardia, tachypnoea and ataxia were recorded in 50 per cent or more of the cases. Constipation, ruminal stasis, salivation and hyposensitivity had likelihood ratios of 3 and above for being associated with hypocalcaemia. Ruminal stasis and hyposensitivity had the likelihood ratios of 0.10 and 0.11 respectively for not being associated with hypocalcaemia.

A six-month-old shiba dog with a one-month history of progressive motor dysfunction showed clinical signs of a cerebellar disorder, including ataxia, dysmetria and intention tremor of the head. Histopathological and ultrastructural studies revealed distended neurons packed with membranous cytoplasmic bodies throughout the central nervous system. The activities of lysosomal acid beta-galactosidase in its leucocytes and liver were less than 2 per cent of the control levels, and the compound accumulated in the brain was identified as GM1 ganglioside. A sibling which died immediately after birth was shown to have a beta-galactosidase deficiency in the brain and visceral organs. A family study revealed that the sire and dam of the probands were heterozygotes with approximately half of the normal level of beta-galactosidase activity, suggesting an autosomal recessive pattern of inheritance.

Between 1995 and 1997 a neurological condition in pheasant poults from 24 sites in England and Scotland was investigated. Affected birds showed varying degrees of ataxia and incoordinated movements and, in severe cases, recumbency, but generally remained alert with their heads held upright. The condition characteristically affected poults from seven weeks of age and the incidence on any one site was low. No significant bacteria were isolated consistently from brain tissue. The condition was characterised histologically by a non-suppurative meningoencephalitis, in which lesions were found predominantly in the cerebellum in 61 of 81 samples examined (75.3 per cent). A non-suppurative myelitis was recorded in 16 of 20 spinal cords examined. No lesions were recorded in peripheral neural tissue and lesions were rare in other tissues. The condition appeared not to have been recorded previously in pheasants. A viral aetiology was suspected but Newcastle disease virus was not involved.

An 11-year-old female crossbred dog showed signs of polyuria, polydipsia, vomiting, posterior weakness and ataxia. Clinical and laboratory findings suggested the diagnosis of polycythaemia vera. The haematological values shown over a six-month period are presented. In four samples some aspects of erythrocyte function (glucose-6-phosphate dehydrogenase [G6PD] and pyruvate kinase [PK] activities, 2,3 diphosphoglycerate [2,3 DPG] concentration, osmotic fragility and intracellular sodium and potassium concentrations) were studied. Variable activities of G6PD and PK, probably related to different reticulocyte number, were detected together with normal osmotic fragility and intracellular sodium and potassium concentrations. 2,3 DPG concentration was higher than normal in all four samples. This could be interpreted as a response to a low tissue perfusion rather than a higher content of 2,3 DPG in red blood cells from the polycythaemic dog.

A four-year-old wire-haired dachshund developed progressive neurological signs of ataxia, intention tremor and finally dysuria. Two years later, histopathology showed that neurons throughout the brain and spinal cord were distended with lipopigment which was also present in macrophages. Ultrastructurally, the pigment in the neurons occurred predominantly as electron-dense membranous whorls and stacks. There were a few vacuolated macrophages in the meninges. Hepatocytes were highly vacuolated and electron microscopy suggested that they were empty membrane-bound vesicles. The disease was diagnosed as mucopolysaccharidosis IIIA because of its similarity to other biochemically confirmed cases in the same breed and in a New Zealand huntaway dog. Additional lesions included calcium oxalate uroliths, severe secondary calcification of tissues including the brain and storage deposits in some neurons, and lesions which may have been associated with high levels of the substrate, heparan sulphate.

Progressive ataxia, with head tremor, developed in 10 captive-born cheetah cubs under six months of age. The condition was usually preceded by coryza and an ocular discharge. Initially the ataxia and weakness affected the hindquarters, then the forelegs, and head tremor developed later. Significant pathological changes were confined to the central nervous system. There was widespread Wallerian degeneration in the funiculi of the spinal cord (except those in the dorsal columns), in the medulla and in the cerebellum. In the cerebellum there was degeneration of Purkinje cells and of the molecular and granular cell layers. There was chromatolysis in the Purkinje cells, the ventral horn cells of the spinal cord and in the neurons of the lateral vestibular nucleus. The olivary nucleus was necrotic. There were foci of inflammatory cells in the molecular layer of the cerebellum and in the medulla. The cause of the disease remains unknown.

Forty-eight horses subjected to elective surgery were randomly assigned to three groups of 16 horses. After premedication with 0.1 mg/kg acepromazine intramuscularly and 0.6 mg/kg xylazine intravenously, anaesthesia was induced either with 2 g thiopentone in 500 ml of a 10 per cent guaifenesin solution, given intravenously at a dose of 1 ml/kg (group TG), or with 100 mg/kg guaifenesin and 2.2 mg/kg ketamine given intravenously (group KG), or with 0.06 mg/kg midazolam, and 2.2 mg/kg ketamine given intravenously (group KM). Anaesthesia was maintained with isoflurane. The mean (sd) end tidal isoflurane concentration (per cent) needed to maintain a light surgical anaesthesia (stage III, plane 2) was significantly lower in group KM (0.91 [0.03]) than in groups TG (1.11 [0.03]) and KG (1.14 [0.03]). The mean (sd) arterial pressure (mmHg) was significantly lower in group KG (67.4 [2.07]) than in groups TC (75.6 [2.23]) and KM (81.0 [2.16]). There were no significant differences in the logarithm of the heart rate, recovery time or quality of recovery between the three induction groups. However, pronounced ataxia was observed in the horses of group KM, especially after periods of anaesthesia lasting less than 75 minutes.

This paper describes the clinical findings and treatment of 67 sheep and goats with listeriosis. In 55 of them the diagnosis was made on the basis of the typical signs, which included vestibular ataxia, circling, head tilt and unilateral cranial nerve deficits, but in 12 animals a definitive diagnosis was made only after postmortem examination. The most significant haematological and biochemical findings were a high haematocrit in 16 animals, a high concentration of total protein in 33, a high concentration of bilirubin in 39 and a high concentration of urea nitrogen in 28 animals. Twenty-eight of the animals had a metabolic acidosis. Thirty-nine animals were treated with antibiotics, intravenous sodium chloride and glucose solutions and sodium bicarbonate. Ten of them survived and the others were euthanased because their condition deteriorated. Of the 10 that survived, nine were able to stand when they were first examined and one was in lateral recumbency. Of 15 animals treated with chloramphenicol, one survived; of 11 animals treated with oxytetracycline, two survived; and of nine animals treated with gentamicin and ampicillin, six survived.

Eighty-one Californian sea lions (Zalophus californianus) with signs of domoic acid toxicity stranded along the coast of California in 1998 when there were blooms of the domoic acid-producing alga Pseudonitzschia australis off-shore. In 2000, a further 184 sea lions stranded with similar clinical signs, but the strandings occurred both during detectable algal blooms and after the blooms had subsided. The clinical signs in these 265 Californian sea lions included seizures, ataxia, head weaving, decreased responsiveness to stimuli and scratching behaviour. Affected animals had high haematocrits, and eosinophil counts, and high activities of serum creatine kinase. They were treated supportively by using fluid therapy, diazepam, lorazepam and phenobarbitone. Fifty-five of the 81 sea lions (68 per cent) affected in 1998 and 81 of the 184 (44 per cent) affected in 2000 died despite the treatment. Three of the 23 sea lions which survived in 1998 were tracked with satellite and radiotransmitters; they travelled as far south as San Miguel Island, California, and survived for at least three months. Eleven of the 129 animals which were released stranded within four months of being released.
