衣原体病是一种由鹦鹉热衣原体(Chlamydia psittaci)所引起的传染病,使多种动物和禽类发病的一种人畜共患病,人感染能引起鹦鹉热和Reiter综合症两种疾病.为了摸清乌兰地区放牧山羊中衣原体的感染状况,为防制该病提供依据,于1997和1998两年对乌兰地区244只放牧山羊进行了血清学调查,现将结果报告如下. 相似文献

<正>羊衣原体病是由鹦鹉热衣原体引起的绵羊、山羊的一种传染病。临床上以发热、流产、死产和产出弱羔为特征。在疾病流行期,也见部分羊表现多发性关节炎、结膜炎等疾患。流行特点。鹦鹉热衣原体可感染多种动物,多为隐性经过。家畜中以牛、羊较为易感,禽类感染后称为"鹦鹉热"或"鸟疫"。许多野生动物和禽类是本菌的自然贮主。患病动物和带菌动物为主要传染 相似文献

陕西省某山羊养殖场发生了一起山羊流产病,经流行病学调查,临床症状和病理剖检观察进行初步诊断;利用布鲁菌虎红平板凝集试验、衣原体间接血凝试剂盒对10份流产母羊血清检测;对病料进行细菌学检测;依据GenBank收录的山羊流产性衣原体基因组设计1对特异性引物,通过PCR方法从病料中扩增衣原体特异性片段。结果表明,根据临床症状和病理变化初步怀疑为布鲁菌和鹦鹉热亲衣原体感染;10份血清检测结果为布鲁菌病血清全部阴性,衣原体感染血清全部为阳性;细菌学检测结果为阴性;PCR结果获得523bp基因片段,测序结果与鹦鹉热亲衣原体100%相似。依据流行病学调查,临床症状和病理剖检观察,病原学和血清学诊断,最终确诊该病为鹦鹉热亲衣原体引起的山羊地方流行性流产。 相似文献

<正>山羊衣原体病是由鹦鹉热衣原体引起的一种传染病,临床以孕羊发热、流产、死产和产出弱羔为特征,严重影响山羊养殖业。鹦鹉热衣原体可感染多种动物,多为隐性经过。家畜中以牛、羊易感,禽类感染后称为"鹦鹉热"或"鸟疫"。许多野生动物和禽类是本菌的自然贮主,患病动物和带菌动物为主要传染源,可通过粪便、尿液、乳汁、泪液、鼻分泌物以及流产的胎儿、胎衣、羊水排出病原体,污染水源、饲料及环境。本病主要经呼吸道、消化道及损伤的皮肤、黏膜感染,也可通过交 相似文献

动物衣原全病主要是由鹦鹉热衣原体感染引起的一种人兽共患传染病。国际兽疫局(OIE)将此病列为二类传染病。衣原体属共包括4个种，即沙眼衣原体、鹦鹉热衣原体、肺炎衣原体和反刍动物衣原体。各种农原体分别引起不同征候群的衣原体病。 相似文献

<正>羊衣原体病是由鹦鹉热衣原体引起的一种亚急性传染性疾病。根据临床症状羊衣原体病可分为流产型、关节炎型及结膜炎型等3种类型[1]。其病原鹦鹉热衣原体是一类不同于细菌和病毒的独特微生物,可感染山羊、绵羊、牛、猪等多种动物,人也可感染发病,因此羊衣原体病对公共卫生也有严重的威胁。随着牛羊养殖的迅速发展,羊衣原体病发病率日益升高,感染羊长期带毒,且无明显症状,对畜牧业形成了重大威胁,不仅造成了巨大的经济损失,而且对人类的身体健康造成严重的危 相似文献

羊衣原体病是由鹦鹉热衣原体引起的绵羊、山羊的一种传染病。病原可通过呼吸道、消化道及损伤的皮肤、黏膜感染,也可通过交配或用患病公羊的精液人工授精感染。羊感染后可引起流产、早产、死产及肺炎、多发性关节炎、脑脊髓炎和腹泻,种公羊发生睾丸炎等病症。它不仅使养羊业蒙受巨大损失,而且对人体健康也构成很大威胁。 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献

In late December 1985, 1485 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1985 and 44% of them responded. Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1988, 1581 small and mixed animal clinics and institutional veterinarians across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1988, and 46% of them responded. Veterinarians reported that 181,577 dogs were blood-tested for heartworm disease and 367 dogs were found with D. immitis microfilariae. Another 60 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number of cases diagnosed in 1988 as 441 (0.24%). 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献

In late December 1986, 1224 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1986; 46% of them responded. Veterinarians reported that 150,989 dogs were blood-tested for microfilariae and 869 dogs were found with heartworm. Another 65 dogs were amicrofilaremic but diagnosed with heartworm disease and one was found with heartworm at necropsy to give the total number diagnosed in 1986 as 935 (0.62%). Heartworm was reported from Manitoba, New Brunswick, Ontario and Quebec, but most (810) of the cases were from Ontario. South-western Ontario continued to be the primary focus of the infection in Canada. There were 103 cases reported from Quebec, mostly from and around Montreal, and 21 cases from Manitoba, from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 33% of the cases were observed with clinical signs of heartworm disease and 81% had a history of not having left Canada. 相似文献
