摘要:

Tuberculosis in a flock of sheep in the Buller district of New Zealand was investigated in 1970. Seventy sheep which had given positive responses to an intradermal tuberculin test were necropsied. Lesions were found in 43 (61%). The lesions ranged from encapsulated, mineralised foci in single lymph nodes, to extensive, soft, caseous lesions involving entire thoracic or abdominal nodes and forming confluent tubercles in dorsal parts of the lung.

摘要:

The concentration of selenium (Se) in liver, whole blood, erythrocytes and plasma, and the activity of glutathione peroxidase (GSH-px) in erythrocytes and plasma were monitored in calves transferred between low Se and high Se pastures to determine how each test responded to changes in dietary selenium concentration.

摘要:

The serological relationship between a New Zealand strain of equine herpesvirus type 1 (EHV 1) isolated from the respiratory form of the disease, and one isolated from an aborted foetus was investigated. Cross neutralization tests were carried out using a plaque reduction test.

摘要:

Three trials were conducted in Central Hawkes Bay and in the Piopio areas of New Zealand in which ewes naturally infected withFasciola hepaticawere treated with ‘Vermadax’ (thiophanate & brotianide.) Liver fluke counts on slaughter showed overall reductions in the number of immature (estimated to be largely 6 weeks and older) and adult liverfluke of 96.0% to 100.0% compared with untreated controls.

摘要:

Eight 1-year-old ewes and 8 yearling heifers were inoculated withL. interrogansserovarbalcmica. All 16 animals had seroconverted by 14 days post inoculation (pi). The only clinical signs related to infection were mild transient temperature elevations between 1 and 9 days pi which were observed in the majority of the inoculated animals. Leptospiruria was detected in 1 of the 8 sheep 18 days pi and leptospires were isolated from the kidney of this sheep at 50 days pi. Five of the 8 heifers were leptospiruric between 6 and 8 weeks pi and leptospires were isolated from kidney cultures of 3 of these heifers at 56 days pi. There was no natural transmission ofbalcanicainfection to control animals run with these infected animals under pasture condition. Although it is possible thatbalcanicainfection occurs sporadically in sheep and cattle in New Zealand we consider that it is unlikely to be maintained endemically in these species.
