摘要:

The importance of correct interpretation of serological test results, common sources of error and problems associated with tests are discussed. In bovine brucellosis, a disease which is ideally suited to serological diagnosis, foetal contact with infection may cause the calf to be a serologically negative carrier. The immune tolerant animal resulting from foetal contact with virus is a major problem in the serological detection of border disease. In Johnes' disease and to a lesser extent inBrucella ovisand leptospiral infections, problems associated with sensitivity and specificity of the tests are stressed. Serovar specificity, cumbersome test procedures and negative tests in the incubation period cause difficulty in the interpretation of serological test results for leptospirosis. The importance of clinical examination, herd histories and alternative diagnostic procedures is important in all diseases. Wherever possible, flocks or herds should be maintained in specific disease-free state. Selection of stock from accredited herds or flocks is the most certain method of Guying non-infected animals.

摘要:

Two case histories are presented to illustrate the clinical and pathological findings of a malignant catarrhal fever-like disease as seen in farmed red deer in New Zealand. Attention is drawn to the similarities with some exotic diseases and the suggestion is made that deer may act as a reservoir for the aetiological agent.

摘要:

A cerebellar neuroaxonal dystrophy in working collie sheep dogs from two properties in New Zealand and one property in Australia is described. Clinical signs developed from 2–4 months of age and included hypermetria, wide-based stance, difficulty in maintaining balance, intention tremor and ataxia. Numerous spheroids, associated with mild Wallerian degeneration, were present in the central cerebellar, adjacent peduncular and folia white matter, and associated cerebellar roof and lateral vestibular nuclei. The history of several affected pups in litters from successive matings of the same sire and dam is suggestive of an autosomal recessive mode of inheritance.

摘要:

The protozoan parasite,Eimeria leuckartiwas present in the ileal mucosa of a 7-month-old Thoroughbred filly which was destroyed with acute peritonitis resulting from perforation of the rectum. The parasite was considered to be of no clinical significance and the signs of colic noted prior to the rectal rupture were related to the vascular lesions caused by infection withDelafondia vulgaris.
