A leucoencephalomyelitis in 6 goat kids 2 to 5 months old is described. The disease was characterised by fever, ataxia, posterior paresis, circling and hyperaesthesia progressing to prostration. The neural lesion was confined to the white matter of the cerebellum and posterior brain stem in 4 kids, but in 2 others the cervical spinal cord was the main site affected. The lesion was characterised microscopically by dense perivascular cuffing with mononuclear cells, infiltration of the parenchyma with macrophages and a proliferation of glial cells and by a marked primary demyelination. In more advanced lesions, areas of the neurophil were replaced by a loose glial scar. There were associated pulmonary lesions of interstitial pneumonitis and hyperplasia of the peribronchiolar lymphoid tissue. Attempts to isolate an aetiological agent and to transmit the disease to young goat kids and lambs were unsuccessful. The disease has not been reported before in Australia but has distinct similarities to an infectious leucoencephalomyelitis of young goats which has been described in North America.

Between 1976 and 1981 a specific neurological disorder of sheep was observed in Ghana. It was encountered on eight properties on some of which it was responsible for losses of up to 72 per cent of the sheep stock in some years. The condition affected mainly adult ewes, and was characterised clinically by a brief period of ataxia, followed by paresis prostration and death in four to five days. Morphological examination of nine affected animals revealed significant lesions only in the central nervous system. These consisted of oedema of the intracellular glial compartment and bilateral, sometimes symmetrical, foci of spongy transformation, malacia and haemorrhage in the grey matter of the brain stem, cerebellum and spinal cord. The aetiology of ataxia/paresis syndrome was not determined but some possibilities are discussed in the context of other naturally occurring and experimental focal malacic disorders in animals.

A retrospective study was conducted of 482 glyphosate calls recorded at the Centre National d'Informations Toxicologiques Veterinaires (CNITV) of France between 1991 and 1994. Most of the calls came from veterinary practitioners (83.8%) and were related to emergencies. In the majority of calls, the CNITV did not assess clinical observations as certain or highly probable glyphosate poisoning. Only 31 cases were assessed as certain or highly probable and were linked with direct ingestion of glyphosate concentrates or sprays in 25 dogs. The symptoms were most frequently described as vomiting, hypersalivation and diarrhea; prostration and paresis were not common. Symptomatic treatment resulted in rapid recovery without sequelae.

The technical grade of xylenes (mixed) (hereafter termed xylenes) contains the three isomeric forms and ethylbenzene (percentage composition shown above). The annual production for 1985 was approximately 7.4 x 108 gallons. Xylenes is used as a solvent and a cleaning agent and as a degreaser and is a constituent of aviation and automobile fuels. Xylenes is also used in the production of benzoic acid, phthalate anhydride, and isophthalic and terephthalic acids as well as their dimethyl esters. Toxicology and carcinogenesis studies of xylenes were conducted in laboratory animals because a large number of workers are exposed and because the long- term effects of exposure to xylenes were not known. Exposure for the present studies was by gavage in corn oil. In single-administration studies, groups of five F344/N rats and B6C3F1 mice of each sex received 500, 1,000, 2,000, 4,000, or 6,000 mg/kg. Administration of xylenes caused deaths at 6,000 mg/kg in rats and mice of each sex and at 4,000 mg/kg in male rats. In rats, clinical signs observed within 24 hours of dosing at 4,000 mg/kg included prostration, muscular incoordination, and loss of hind limb movement; these effects continued through the second week of observation. Tremors, prone position, and slowed breathing were recorded for mice on day 3, but all mice appeared normal by the end of the 2- week observation period. In 14- day studies, groups of five rats of each sex were administered 0, 125, 250, 500, 1,000, or 2,000 mg/kg, and groups of five mice of each sex received 0, 250, 500, 1,000, 2,000, or 4,000 mg/kg. Chemical- related mortality occurred only at 2,000 mg/kg in rats and at 4,000 mg/kg in mice. Rats and mice exhibited shallow breathing and prostration within 48 hours following dosing at 2,000 mg/kg. These signs persisted until day 12 for rats, but no clinical signs were noted during the second week for mice. In 13- week studies, groups of 10 rats of each sex received 0, 62.5, 125, 250, 500, or 1,000 mg/kg, and groups of 10 mice of each sex received 0, 125, 250, 500, 1,000, or 2,000 mg/kg. No deaths or clinical signs of toxicity were recorded in rats. However, high dose male rats gained 15% less weight and females 8% less weight than did the vehicle controls. Two female mice died at the 2,000 mg/kg dose. Lethargy, short and shallow breathing, unsteadiness, tremors, and paresis were observed for both sexes in the 2,000 mg/kg group within 5- 10 minutes after dosing and lasted for 15- 60 minutes. Two- year toxicology and carcinogenesis studies were conducted by administering 0, 250, or 500 mg/kg xylenes in corn oil by gavage to groups of 50 F344/N rats of each sex, 5 days per week for 103 weeks. Groups of 50 B6C3F1 mice of each sex were administered 0, 500, or 1,000 mg/kg xylenes on the same schedule. Although the mortality was dose related in male rats (final survival: vehicle control, 36/50; low dose, 26/50; high dose, 20/50), many of the early deaths in the dosed males were gavage related. Body weights of the high dose male rats were 5%- 8% lower than those of the vehicle controls after week 59. The mean body weights of low dose and vehicle control male rats and those of dosed and vehicle control female rats were comparable. Survival rates of female rats and both sexes of dosed mice were not significantly different from those of the vehicle controls. The mean weights of dosed male and female mice were comparable to those of the vehicle controls. Hyperactivity lasting 5- 30 minutes was observed in high dose mice after dosing, beginning after week 4 and continuing through week 103. At no site was the incidence of nonneoplastic or neoplastic lesions in dosed rats or mice of either sex considered to be related to the administration of xylenes. Neither xylenes nor any of its components (o- xylene, m-xylene, p- xylene, or ethylbenzene) were mutagenic when tested with or without metabolic activation in Salmonella typhimurium strains TA100, TA1535, TA97, or TA98 with the preincubation protocol. In addition, ethylbenzene was tested in cytogenetic assays using cultured Cetic assays using cultured Chinese hamster ovary cells both with and without metabolic activation; neither sister- chromatid exchanges nor chromosomal aberrations were induced by ethylbenzene. An audit of the experimental data was conducted for the 2-year studies of xylenes. No data discrepancies were found that influenced the final interpretations. Under the conditions of these 2-year gavage studies, there was no evidence of carcinogenicity of xylenes (mixed) for male or female F344/N rats given 250 or 500 mg/kg or for male or female B6C3F1 mice given 500 or 1,000 mg/kg.

The performance of clinical signs as a diagnostic test for the detection of BTV-8 outbreaks during the 2006-epidemic in The Netherlands was evaluated by constructing and analysing receiver operating characteristic (ROC) curves. The area under the ROC curve of the BT-associated clinical signs in cattle was 0.77. An optimal efficient test (maximising both sensitivity and specificity) in cattle herds combined a sensitivity (Se) of 67% with a specificity (Sp) of 72%, comprising the following clinical signs: ulcerations and/or erosions of oral mucosa or erosions of lips/crusts in or around nostrils or oedema of the nose or hyperaemic/purple coloration of tongue, tongue protrusion or coronitis or apathy/tiredness or muscle necrosis, stiffness of limbs or loathing or refusal to move, prostration or torticollis or anoestrus. The area under the ROC curve of the BT-associated clinical signs in sheep was 0.81. The optimal efficient test in sheep flocks combined a Se of 76% with a Sp of 72%, comprising the following clinical signs: ulcerations of oral mucosa or serous nasal discharge or erosions/ulceration of tongue mucosa or hypersensitivity of the skin or muscle necrosis, stiffness of limbs or coronitis or grinding of teeth or salivation or weakness/paresis.
