Abstract Extract Recognition that one infective agent could cause ram epididymitis and ewe abortion in New Zealand was due to McFarlane et al. (1952). The organism was not identified at that time, but Buddie and Boyes (1953) classified it in the genus Brucella—possibly a variant of Br. melitensis. This finding provided a basis for research on control and treatment of the disease. The present paper describes studies on one aspect of this problem, the chemotherapy of affected rams. 相似文献

Abstract Extract Increasing references have been made in the recent veterinary literature to malacic diseases of the nervous system in sheep and other animals. Plowright (1954) and Innes and Plowright (1955) have described a focal symmetrical spinal poliomalacia of unknown aetiology in sheep in Kenya. In the U.S.A., Cordy (1954) has described a focal symmetrical encephalomalacia of horses following the ingestion of a species of thistle, and Jensen et al. (1956) have described an idiopathic polio-encephalomalacia in cattle and sheep. In New Zealand, Hartley (1956) has described a focal symmetrical encephalomalacia (F.S.E.) of lambs that may be related to the sublethal effects of the toxin of Clostridium perfringens (welchii) Type D. Smith (1957) has described widespread lesions of polio-encephalomalacia together with eosinophilic meningoencephalitis in sodium chloride poisoning of swine. 相似文献

Abstract Extract Surveys on perinatal infection in lambs in New Zealand have been reported and the pathology and bacteriology of the conditions described (Hartley and Boyes, 1955, 1964; McFarlane, 1955; Hartley and Kater, 1964). Potentially pathogenic organisms were isolated from 58 to 288 lambs from five flocks, Clostridium septicum being isolated from five of these cases (Hartley and Boyes, 1955). In another survey, 5.5% of lambs born dead or dying up to 4 weeks of age died from navel infection. Clostridium septicum was isolated from 69% of 48 consecutive cases (Hartley and Boyes, 1964). McFarlane (1955) recorded that 7.3% of perinatal mortality was due to navel infection but no bacteriology was carried out nor was the organism suspected stated. On individual farms, up to 15% of lambs recorded died from navel ill. It should be pointed out that, in this survey, only small numbers of lambs were received from some properties. 相似文献

Abstract Extract An infectious epididymitis of rams caused by Brucella ovis (Buddie, 1956) infection, first described in Australia (Simmons and Boyes, 1953) and New Zealand (Buddie and Boyes, 1953) was recognized subsequently in Czechoslovakia (Gdovin et al, 1955), the United States (McGowan and Shultz, 1956), South Africa (Van Rensburg et al, 1958), Rumania (Tudoriu, et al, 1958), and South America (Dr Justo Zomara B, 1961, pers. comm.). As the infection can affect ram fertility and, further, can be responsible for abortion in ewes and perinatal mortality in lambs, attention has been directed to the development, evaluation, and application of control measures in a number of important sheep-raising countries. 相似文献

Abstract Extract Drake et al. (1960) have shown that selenium will control outbreaks of lamb and hogget ill-thrift on the pumice soils of the Rotorua-Taupo area. As an ill-thrift problem also exists in calves on the newly-broken-in farms in the same area, it was decided to investigate the effect of oral selenium and other minerals in the control of this problem. 相似文献

Abstract Extract Sir, — Correspondence in your journal has indicated that there is some divergence of opinion about the efficacy of the complement fixation (CF) test for the diagnosis of ovine brucellosis (Brucella ovis) (1) (2) (3) (4) . A number of letters which have recently been received at the Animal Health Reference Laboratory indicate that this issue is not yet fully resolved. We believe that part of the difficulty is due to misunderstanding about the use and interpretation of the test, and we would therefore like to comment. 相似文献

Abstract Extract Caprine arthritis encephalitis (CAE) is a disease of goats of any breed, sex and age, caused by a retrovirus related to, but distinct from, the maedi-visna virus which affects sheep.(4) (10) Both infections are included among the so-called slow virus diseases which are characterised by a long incubation period, protracted clinical course and persistent infection. Maedi-visna is not present in New Zealand but CAE has been detected in a number of goat flocks. 相似文献

Abstract Extract Recent research has shown that the gene frequency for mannosidosis (pseudolipidosis) may approximate 0.05 in pedigree Angus herds (Jolly, unpublished data). As epidemiological studies suggest an equal frequency in commercial non-pedigree herds, the disease is elf economic importance to the national beef industry. Mannosidosis is an inherited lysosomal storage disease associated with a defect in catabolism, of the heterosaccharide fractioln of glycoproteins (Whittem and Walker, 1957; Jolly 1971; Hocking et al., 1972; Phillips et al., 1974). Whereas animals with mannosidosis have negligible tissue sand plasma levels of α-mannosidase, heterozygotes having one normal gene and one defective gene have approximately half the normal level of enzyme in their tissues and plasma. This observation forms the basis for a control programme in which heterozygotes are identified by their plasma α-mannosidase 1evels (Jolly et al., 1973, 1974a, b). 相似文献

Abstract Extract Sir, — Leptospira interrogans serovar balcanica is now recognised as a widespread infection among opossums in New Zealand (2) and the possibility of domestic stock acting as accidental hosts has recently been demonstrated. (3) With the recent development of hardjo vaccines (1) (4) for controlling infection with this serovar in the maintenance hosts, stock could be left vulnerable to infection with other prevalent serovars such as balcanica. 相似文献

Abstract Extract In New Zealand, cobalt-containing drenches are recommended for the field diagnosis of cobalt deficiency, but find little use as a routine method of controlling the disease. For the latter purpose, cobaltized licks have a place on extensively-grazed untopdressed hill country. Otherwise, topdressing pastures annually with cobalt sulphate, usually as cobaltized superphosphate, has proved the best method of prevention (N.Z. Dept. Agric, 1954; Andrews, 1956). In Australia, however, greater reliance has been placed on drenches and licks, partly because cobalt topdressing is regarded as uneconomic on the extensive undeveloped holdings usually associated with cobalt deficiency in that country, and partly because the effects of cobalt applied to the land have often proved ephemeral, particularly on the acutely-deficient calcareous coastal sands (Lee, 1950; Bennetts, 1955). However, recent work in South Australia opens up an entirely new approach to the control of cobalt deficiency disease. Dewey et al. (1958) report that when semi-porous pellets containing cobaltic oxide are administered to sheep they are retained in the reticulum, or less commonly in the rumen, and release a continuous and adequate supply of cobalt to the animal. Phalaris staggers and cobalt deficiency disease can be prevented in this way. 相似文献

Abstract Extract The results of recent New Zealand studies (Brunsdon, 1968, 1969) have indicated the potential pathogenicity of trichostrongyle worm infection in calves reared on pasture underdairy-type management and have confirmed overseas findings regarding difficulties associated with- the- diagnosis of trichostrongyle disease in general and of the various syndromes of ostertagiasis in particular (Anderson et al., 1965; Michel, 1968). 相似文献

Abstract Extract Colitis X is a peracute, sporadic noncontagious disease affecting horses of all ages, characterized by sudden onset of shock, dehydration and foetid diarrhoea (Rooney et al., 1963; Pickrell, 1968). Rooney et al. (1966) have described a form of colitis X without diarrhoea. Otubreaks of the disease which affected numerous horses under the same conditions of management have been described (Rooney et al., 1963; W. P. C. Richards, pers. comm.). 相似文献

Abstract Extract A gram-negative pleomorphic facultative aerobic organism, indistinguishable morphologically and culturally from that isolated from suppurative epididymitis in rams and described by Dodd &; Hartley (1955), has, over the last five years, been isolated at this laboratory on more than ten occasions from polytenosynovitis and pyaemia in lambs, and on one occasion from mastitis in a ewe. It still remains to characterize and classify this organism, but Roberts has made a detailed comparison of it with his Histophilus ovis (Roberts, 1956) and considers that the two are indistinguishable (Roberts, 1958, pers. comm.). 相似文献

Abstract Extract Both Candida albicans and C. tropicalis have been implicated in cases of bovine mastitis following udder infusion with antibiotics (Loken et al., 1959). In some cases (Tucker, 1954), contamination of the diluting fluid and teats with yeasts from the operator has been given as the cause, while in other cases (Stuart, 1951; Hulse, 1952), yeasts from brewer's grains on which the cows were feeding have been blamed. 相似文献
