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 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

Abstract Extract The ciliate protozoan parasite Balantidium coli is considered by Hagan (1947) commonly to infest swine, in which it occasionally produces, ulcerative colitis and diarrhoea. Humans are subject to infestation only rarely, and those most commonly affected associate with swine. A preliminary report by Norgarin (1957) records the occurrence of B. coli in cattle, and Hayesand Jordan (1956) record its presence in worm infested dogs. 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 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 Canine hip dysplasia was first recognized 40 years ago (Schnelle, 1935) and since then it has been accepted as a common pathological condition of the coxofemoral joint. It is a disease that is characterized by an abnormal laxity of the joint which may or may not cause clinical signs of hind-limb lameness. Although it appears to be most prevalent in the larger breeds of dogs (Schnelle, 1954; Riser 1963; Larsen and Corley, 1970), it does occur in smaller breeds and in crossbred animals (Gustaffson et al., 1972; Lust et al., 1973). In recent years many of the large breeds of dogs have become more popular in New Zealand and this popularity has seemingly led to an increase, in the incidence of hip dysplasia. Because the condition is thought to be due to a heritable defect, attempts to eradicate it by selection and mating of “phenotypically normal” animals have been commonplace throughout the world. In addition, many methods of treatment or prevention of the disease in the individual animal have been recommended by veterinarians. 相似文献

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 Much work has been, carried out in New Zealand to ascertain the response in young sheep to drenching with anthelmintics (for review see Whitten, 1954). Clarke &; Filmer (1958) have also examined response to drenching in their studies on hogget' ill-thrift. As Whitten (1954) has shown, results of past drenching trials have been extremely variable. In some cases little or no response has been observed, in others considerable increases; in weight gains have been achieved. More recently, Robertson (1963) has summarized the results of part of an extensive series of country-wide post-weaning drenching trials conducted by the Department of Agriculture with the new anthelmintic thiabendazole. In those trials consistent, weight gain responses were recorded in favour of the drenched animals. However, most of the published data are from trials involving strategic drenching programmes designed to control or limit infestation rather than to suppress completely, patent infestation. Most of these trials have been confined to late summer, autumn and winter, and few have attempted to cover the entire first year of young sheep. Furthermore, little attempt has hitherto been made to correlate responses obtained with the changing degree and species composition of infestation throughout the course of the trial. 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 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 Feild outbreaks of acute lameness in sheep in New Zealand are usually attributed to contagious footrot (Fusiformis nodosus) (Beveridge, 1941), foot abscess (Sphaerophorus necrophorus) (Gregory, 1939), or so-called “nutritional scald” Occasionally Erysipelothrix rhusio pathiae is also responsible (Whitten, 1951). 相似文献

Abstract Extract An acute epididymitis affecting mainly young rams and associated with a gram-negative pleomorphic organism was first reported in New Zealand in 1955 (1). Subsequently a similar syndrome attributed to Actinobacillus seminis has been reported in Border Leicester and other rams in Australia (2) (3) (4). A like condition also described in Australia in a single crossbred ram was causally attributed to Histophilus ovis (5). Actinobacillus seminis was isolated from an epididymal infection in a Rambouillet ram in America (6) and from a Dorper ram in South Africa(7). 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 Between November 1972 and February 1973, severe outbreaks of a disease in broilers, characterized by congestive heart failure,, hydropericardium, liver shrinkage, ascites, and sometimes subcutaneous oedema were observed in the North Island. The disease resembled enzootic fatal syncope (toxic heart degeneration) described earlier in laying hens in New Zealand (Fischel, 1946), chick edema disease seen in the U.S.A. (Schmittle et al., 1958; Sanger et al., 1958), possible fat intoxication in chickens reported from Britain (Wannop and Chubb, 1961), and alimentary toxaemia or water belly ascites experienced in Australia (Sinkovic, 1961). 相似文献

Abstract Extract Sir, — The use of corticosteroids to induce early parturition to obtain a concentrated calving period has been widely accepted in New Zealand. Retention of the placenta following treatment with corticosteroids has been described by Adams (1969), Lauderdale (1972) and Jochle et al. (1972). Welch et al. (1973), using dexamethasone trimethylacetate* in the Huntly and Bay of Plenty areas, reported that calf mortality was disturbingly high — 31.3% and 17.1% for the respective areas. Despite having no apparent effect on milk production or subsequent fertility it is possible pre-existing infections may be exacerbated by the use of corticosteroids. 相似文献

Abstract Extract Mannosidosis, a lethal inherited neurological disease associated with a deficiency of the lysosomal enzyme α-mannosidase (Hocking et al., 1972) has been described clinically as affecting Angus calves usually in their firstyear of life (Whittem and Walker, 1957; Jolly, 1970, 1975). Although it has been suspected as a significant cause of neonatal mortality in herds at risk, figures and diagnosis supporting such an hypothesis have not been available. 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 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
