Abstract Extract Sir, — The leptospiral serovars that have been cultured in New Zealand are pomona, copenhageni, ballum and hardjo. (Anon., 1951; Kirschner and Gray, 1951; Anon., 1967a; Lake, 1973, respectively.) Serological evidence of serovar tarassovi has been published (Russell and Hansen, 1958) but it is believed that until now no members of this serogroup have been isolated in New Zealand. 相似文献

Abstract Extract Madam:– Aujeszky's disease (AD) was first diagnosed in New Zealand in 1976.(1) While elinical AD has been uncommon and the disease has had no appreeiable impact on the production of pigmeat for the domestic market, the presence of infection denies New Zealand pigmeat acccss to a number of overseas markets.(1) Access to these could be obtained if meat were derived from herds certified free from AD. 相似文献

Abstract Extract The results of the 1965–6 New Zealand national mastitis survey (Anon., 1967) indicated that β-haemolytic staphylococci were the most common bacteria isolated from the milk of dairy cows. Effective control of β-haemolytic stapyhlococci on a national scaledepends ultimately upon an understanding of population changes of this organism within the cow and within the herd. 相似文献

Abstract Extract Bovine Leptospirosis was first recognized in New Zealand in 1950 (Anon., 1951). Since then the infection has become widespread, particularly during wet spring and summer months (Anon., 1973). In calves, infection with serotype pomona frequently gives rise to haemoglobinuria and general malaise, while symptoms such as loss of condition and pendulous abdomens which appear suddenly and are followed by sudden death have been associated with copenhageni infections (Dodd and Brackenridge, 1960). 相似文献

Abstract Extract The equine lungworm was first reorded in a donkey (Equus asinus) and named Strongylus arnfieldi by Cobbold (1884). Later it was recognized in the horse by Railliet and placed in the genus Dictyocaulus by Railliet and Henry in 1907. Numerous reports describe its cosmapolitan distribution although the cases de- scribed below appear to be the first published records of it from New Zealand, apart from a Department of Agriculture Report (Anon., 1966). 相似文献

Abstract Extract Published records of Escherichia coli infection in lambs have appeared with increasing frequency in recent years. Reports have come from Australia (Roberts, 1957, 1958; Charles, 1957) and from Britain (Terlecki and Shaw, 1959; Rees, 1958; Hughes, 1962). In the Australian outbreaks, the age of affected lambs ranged from three to eight weeks, while in the British outbreaks lambs became affected within one day of birth. In both countries the illness lasted from one to three days. Characteristically, the infection localized in the central nervous system leading to purulent meningo-encephahtis, and in the joints causing fibrino-purulent arthritis. 相似文献

Abstract Extract In spite of numerous publications on the salmonellae and their effects on various hosts, few countries can assess accurately the annual toll of human illness or economic losses in. livestock as a result of these infections. Attempts are being made, at both international and national levels, to remedy this deficiency, particularly as food-borne salmonellosis in countries with high standards of living and hygiene is becoming a very real problem. Increasing mass food preparation, inadequate storage facilities or methods, a trend towards eating raw or insufficiently cooked fcods, increasing international trade, and possibly decreasing personal resistance, have all been cited as contributing factors. Epidemiological studies have documented the vulnerability of the young, the elderly and those with intercurrent disease or those living in institutions. As the main source of infection for man is food of animal origin (Anon., 1967a), all aspects of the livestock and food industries can expect increasing surveillance. In this review it is proposed to discuss recent advances in the detection of Salmonella organisms in livestock and their environment, as well as the application of control measures relevant to New Zealand farming and industry. 相似文献

Abstract Extract Cambendazole, isopropy1 2-(4-thiazoly1)-5-benzimidazolecarbamate, has been reported to be a highly efficient anthelmintic against gastro-intestinal nematodes of cattle (Egerton et al., 1970; Baker and Walters, 1971; Ciordia and McCampbell, 1971; Benz, 1971a, b; Restani, 1971). Efficacy against the cattle lungworm, Dictyocaulus viviparus, has also been reported as high (Rubin, 1972; Gibbs and Gupta, 1972; Baker et al., 1972). This paperreports the results of four controlled critical efficacy trials with cambendazole against naturally acquired nematode infections in cattle. 相似文献

Abstract Extract Rural veterinary practice faces difficulties in many parts of the world. Falling farm incomes and increasing costs have sometimes resulted in reduced use of veterinary services. There seems to be widespread agreement that an increased emphasis on preventive medicine would improve the situation for both the farmer and his veterinarian. There appear to be no commonly agreed formal criteria for the development and evaluation of health programmes, either in human or veterinary medicine, but increasing attention is being paid to the problem(1) (12) (14) (15), In some ways the evaluation of animal health programmes should be the easier, for there are fewer ethical problems and economic criteria are of paramount importance in rural practice. 相似文献

Abstract Extract Parainfluenza type 3(Pl3) virus has been associated with upper respiratory disease of cattle in many countries (Hoerlein et al., 1959; Bögel, 1961; Reisinger, 1962; Jolly and Ditchfield, 1965). However, PI3 virus has not been isolated from cattle with respiratory disease in New Zealand although a serological study found that 89.3% of cows had significant levels of antibody against PI3 virus (Pastier and Hansen, 1966). In most cases infections are subclinical, and there is little evidence to suggest that PI3 virus is an important cause of disease in New Zealand cattle (Jolly, 1967). This communication records an outbreak of upper respiratory disease in cattle from which PI3 virus was isolated. 相似文献

Abstract Extract Little published data is available on the distribution and prevalence of viral diseases in the New Zealand cattle population. Infectious bovine rhinotracheitis (IBR) virus(4) (5) (7) and bovine virus diarrhoea (BVD) virus (5) (7) (l0) appear on serological grounds to be widespread. A serological survey by Fastier and Hansen (7) also suggests that parainfluenza type 3 (PI3) virus is common in the North Island. 相似文献

Abstract Extract Spontaneous glomerulonephritis has been considered an uncommon and ill-defined disease in domestic animals (Jubb and Kennedy, 1970). In a survey of 236 cases of nephritis in horses, cattle, sheep, pigs and dogs, Langham and Hallman (1941) detected primary glomerular abnormalities in only 7. However, recent studies incorporating electron microscopic, or immunofluorescence examination, or both, of renal tissue suggest that glomerulonephritis is not uncommon. During the past 5 years it has been reported in sheep (Angus et al., 1973), dogs (Krohn et al., 1973) and cats (Slauson et al., 1971; Farrow and Huxtable, 1971), and in 6 of 45 horses examined at a commercial slaughterhouse in the U.S.A. (Banks and Henson, 1972). 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 Despite many viruses having been isolated from bovine respiratory and intestinal tracts, only those of bovine virus diarrhoea (BVD), bovine parainfluenza 3 (PI 3) and infectious bovine rhinotracheitis-infectious pustular vulvovaginitis (IBR) have so far been associated with specific clinical complexes. Serological surveys have demonstrated the wide geographical distribution of all three viruses (Huck, 1962; Paterson, 1962; French and Snowdon, 1964; Dawson and Darbyshire, 1964), although so far only IBR has been confirmed as being present in New Zealand (Webster and Manktelow, 1959). However, in view of a previous outbreak of a mucosal-like disease (Salisbury etal., 1961) together with the frequent occurrence of upper respiratory tract symptoms, it seemed most unlikely that other members of this virus trio would be absent from cattle in this country. 相似文献

Abstract Extract Despite the importance of the beef and dairy industries in this country, little attention has been given to parasitic gastroenteritis as an animal health problem in cattle, although McMeekan (1954) has stated that helminths are most commonly associated with severe unthriftiness and losses in dairy calves after weaning. Apart from a recent report of a drenching trial in cattle (Cairns and Gallagher, 1964), there is a complete lack of published information on either the importance and prevalence of the disease in New Zealand, or on the host-parasite relationships concerned in the epidemiology of the disease. Similarly the literature is devoid of data relating to the incidence and distribution of the various parasite species. 相似文献

Abstract Extract Information about diseases in domestic fowls in New Zealand is contained in two books (Anon., 1965; Anon., 1971). The following diseases have been the subject of separate reports: Salmonella newington infection (Flannery, 1954); lead poisoning (Salisbury et al, 1958); Ornithonyssus sylviarum infestation (Thomas and Watson, 1958); infectious laryngotracheitis (Webster, 1959); mycoplasmosis (Pohl, 1966); infectious bronchitis (Pohl, 1967); uraemia (Pohl, 1968); coccidiosis (Pohl, 1969); vibriosis (Pohl, et al, 1969) and capillariasis (Rickard and Pohl, 1969). 相似文献

Abstract Extract The nature of the agent causing hairy shaker disease of lambs in New Zealand is uncertain. A report by Manktelow et al. (1969) demonstrated the transmissibility of the disease, using homogenized tissue as the inoculum, and drew attention to its similarity on clinical and pathological grounds to the condition of Border disease found in the United Kingdom. Transmission of Border disease using homogenized tissues had been previously reported by Dickinson and Barlow (1967), Shaw et al. (1967) and Barlow and Gardiner (1969). 相似文献

Abstract Extract In New Zealand, Leptospirosis of cattle is an important zoonosis. Human leptospirosis, one of the most common of the) notifiable diseases (Christmas et al., 1974) is almost exclusively a disease of dairy farmers. Clinical signs of bovine Leptospira infections are frequently not observed (Sullivan, 1974). Consequently, serological tests are often used to detect leptospirosis in cattle. The microscopic agglutination (MA) test is fairly serotypespecific, but it is tedious to perform and requires potentially hazardous living cultures. The complement fixation (CF) test is less serotype-specific, uses killed organisms, and may be a better indicator of recent infection (Hodges and Ris, 1974). Both tests require a variety of serotypes to identify those causing the infection. 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
