摘要:

Before weaning, some young pigs in a research piggery excreted in their faeces a weakly haemolytic non-enterotoxigenic serotype ofEscherichia coli. After weaning, all of the pigs excreted strongly haemolyticEscherichia coliof known enteropathogenic serotypes (0-138 and 0-139). The 0-138 serotype produced vero cell toxin, whilst the 0-139 serotype elaborated heat labile enterotoxin. Haemolytic enterotoxigenicE. coliwere also recovered from three-week-old unweaned piglets with so-called ‘milk scours’ and from pigs with post-weaning diarrhoea on two local commercial piggeries. Selected haemolytic isolates were compared using serotyping, bacterial restriction endonuclease DNA analysis (BRENDA) and incompatibility grouping. The three typing methods divided most of the isolates into the same groupings; the exceptions were two isolates with the same BRENDA pattern and incompatibility group, but with different H-serotypes, and eleven isolates with the same serotype and BRENDA pattern but which showed differences in colony compatibility such that they were divided into five subgroups of a single incompatibility type.

摘要:

Of 32 calves given an unknown amount of a pluronic bloat mixture with their milk, 28 died in convulsions over 24 hours. Supportive therapy was unsuccessful. Concentrations of pluronic present in abomasal and rumenal contents supported a diagnosis of pluronic poisoning.

摘要:

An aged domestic shorthaired cat was presented for examination because of a six week history of weight loss, diarrhoea and increased appetite. Clinical examination revealed the cat to be emaciated, icteric and the liver was enlarged. Laboratory tests confirmed the presence of hepatic disease and radiographic examination showed hepatomegaly and ascites together with an enlarged globular heart. Ultrasonography showed a heart of normal size surrounded by tissue and/or fluid within the pericardial sac.

摘要:

A severe, fatal, exudative peritonitis was investigated in a flock of 100 breeding fitchMustela putorius furo. The presence of enteric flora within the lesions and steel spicules within the stomach contents suggested that this disease may have been caused by steel fragments perforating the intestine. Scoring and pitting of a steel mincer plate used for food preparation consistent with the size and shape of the steel particles found in the stomach, further supported this hypothesis. There were no further cases when the feed source was changed.

摘要:

To determine the prevalence of excessively worn incisors (XSW) and periodontal disease (PD) in sheep in Dunedin City, Silverpeaks, Bruce and Clutha Counties, the incisors of 4049 mixed age ewes on 83 farms selected at random were examined between December 1983 and February 1984. Of these ewes, 14.9% had XSW (11.7% moderate, 3.2% severe), 13.7% had PD (10.5% moderate, 3.2% severe) and 71.4% had sound mouths. An additional 43 ewes had miscellaneous incisor faults, and these were excluded from the survey. Seventeen (20.5%) and 25 (30.1%) farms had >20% ewes with XSW and PD respectively. On two farms only did XSW and PD each occur at a prevalence of >15%. No association was found between the prevalence of XSW or PD and body condition score, breed or farm topography.
