Future options for brucellosis surveillance in New Zealand beef herds     

MacDiarmid SC 《New Zealand veterinary journal》1988,36(1):39-42

It is probable that bovine brucellosis will be eradicated from New Zealand by 1990. However, continued surveillance for the disease will have to be maintained for a number of years. This paper examines alternative methods of surveillance in beef herds with a view to ensuring that the most cost effective method is used. The three surveillance methods examined are the present automated complement fixation test, abattoir surveillance, and a system based on a delayed hypersensitivity skin test using a purified Brucella protein antigen. It is concluded that despite the relatively low sensitivity of the skin test the probability of its identifying herds as infected is likely to be greater in practice than abattoir surveillance. The skin test is cheaper than the present complement fixation test.  相似文献   

A study of periodontal disease in sheep over a twelve month period     

Laws AJ  Frisken KW  Orr MB 《New Zealand veterinary journal》1988,36(1):32-34

Sheep affected by broken mouth periodontal disease (P.D.) were examined over a twelve month period for different clinical parameters. It is suggested that P.D. in sheep is an episodic phenomenon similar to human P.D., and that only a few animals with signs of P.D. may undergo clinically significant destruction over a yearly period. No single parameter could reliably predict future deterioration in other parameters.  相似文献

An outbreak of malignant catarrhal fever in Père David's deer (Elaphurus davidianus)     

Orr MB  Mackintosh CG 《New Zealand veterinary journal》1988,36(1):19-21

Thirteen (54%) of 24 Père David's deer (Eluphurus duvidianus) imported from England died of malignant catarrhal fever (MCF) within a year of arrival at Invermay Agricultural Centre. The duration of clinical illness was from one to approximately 33 days, and the most common clinical signs were depression, a hunched stance and diarrhoea. On post-mortem examination, most deer showed recent localised haemorrhages, often into the large intestine. In all deer there was histological vasculitis especially in the brain.  相似文献   

Blood thiamine levels in normal cattle and sheep at pasture     

Hill JH  Rammell CG  Forbes S 《New Zealand veterinary journal》1988,36(2):49-50

Analysis of whole blood samples from 174 cattle and, 174 sheep from 3 geographical regions of New Zealand over a 10 month period showed a mean (range) thiamine level of 122 nmol/l (71-237 nmol/l) for cattle and 118 nmol/l (67-227 nmol/l) for sheep. Regional and seasonal differences were noted with levels tending to rise over the summer period. A reference range of 75-185 nmol/l is proposed for both cattle and sheep to cover these variations. Levels below 50 nmol/l are considered indicative of deficiency.  相似文献

Turbulence and change--the veterinary profession in a competitive environment     

Fay MT  Bell JD 《New Zealand veterinary journal》1988,36(4):177-183

This paper examines the views of members of the veterinary profession towards the change in orientation of professional practice that is occurring. It contrasts the values of veterinarians with those of doctors, dentists, lawyers and accountants. Particular attention is given to the areas of business efficiency, competition and advertising. Data was derived from self-completion questionnaires containing 40 Likert scales which were mailed to 300 members of each of the five professions.  相似文献

The detection of Mycobacterium paratuberculosis in bovine faeces by isolation and the comparison of isolation with the examination of stained smears by light microscopy     

Ris DR  Hamel KL  Ayling JM 《New Zealand veterinary journal》1988,36(3):112-114

The detection of Mycobacterium paratuberculosis organisms in bovine faeces by isolation was compared with that by the microscopical examination of Ziehl-Neelsen stained faecal smears for the presence of clumps of acid-fast M. paratuberculosis organisms. Faeces were obtained from cattle naturally or experimentally infected with M. paratuberculosis as well as from uninfected cattle. Microscopical examination was an unreliable method for the detection of M. paratuberculosis organisms, since the organisms were only detected in 99 (=55.9%) of 177 culturally positive faecal samples. 1111 addition, clumps of acid-fast organisms indistinguishable from M. paratuberculosis were also observed iin three of 18 samples from cattle free from Johne's disease and in 18 of 37 culturally negative samples from paratuberculous cattle. When M. paratuberculosis organisms were added to faeces from an uninfected cow, results showed that isolation attempts should be positive when 15 or more M. paratuberculosis organisms per gram of faeces are present.  相似文献
