猪传染性胸膜肺炎是猪的一种呼吸系统疾病，其病原为猪胸膜肺炎放线杆菌。急性病例以纤维素性出血性胸膜肺炎、慢性病例以纤维素性坏死性胸膜肺炎为主要特征。各种年龄的猪均可感染，导致生产性能下降，并能致死，给养猪业带来严重的经济损失。随着畜产品的大流通，品种的快速更新，该病在铁岭市已有发生。现就我市一猪场发生猪传染性胸膜肺炎的诊断与防制报告如下。 相似文献

猪传染性胸膜肺炎是由猪胸膜肺炎放线杆菌引起的猪的一种呼吸道系统传染病，急性病例以纤维素性出血性胸膜肺炎为特征，慢性病例以纤维素性坏死性胸膜肺炎为主要特征。近年来，随着集约化养猪业的不断发展，本病在我国呈现日趋严重的发病趋势。如何控制本病的蔓延与危害，已成为当前养猪工作者十分关注的一个问题。为此，广西贺州市八步区畜牧局特地进行了猪传染性胸膜肺炎活疫苗预防该病的应用效果试验。 相似文献

猪传染性胸膜肺炎是由胸膜肺炎放线杆菌( Actinobaccillus pleuropneumoniae,A P P.又名胸膜肺炎嗜血杆菌 )引起的猪的一种严重呼吸系统传染病。急性病例以纤维素性出血性胸膜肺炎、慢性病例以纤维素性坏死性胸膜肺炎为主要特征。该病在世界上发现较晚 ,60～ 70年代在美洲和欧亚的一些国家陆续有所报道 ,近年来在全世界所有养猪国家的流行日趋严重 ,因急性病例死亡率高 ,慢性病例生长缓慢 ,诊断困难 ,无特效治疗药物 ,给养猪业带来严重的经济损失。 1 987年杨旭夫等首次证明了该病在我国的存在。随着猪种交流和市场流通 ,本病已在我国开始… 相似文献

猪传染性胸膜肺炎是由胸膜肺炎放线杆菌引起猪呼吸系统的一种急性接触性传染病。以急性纤维素性胸膜肺炎或慢性局灶性坏死性肺炎为特征性病变。急性病例死亡率高,慢性病例常可耐过。该病引起猪的高度呼吸困难,发生急性败血病而突然死亡。感染后存活的育肥猪生长缓慢,日增重和饲料报酬下降,而耐过的种猪因带菌往往成为潜在的污染源, 相似文献

在诊断猪气喘病时,应与猪肺疫和猪传染性胸膜肺炎做好鉴别诊断。猪肺疫急性病例呈败血症和纤维素性胸膜肺炎症状,全身症状较重,病程较短,剖检时见败血症和纤维素性胸膜肺炎变化。猪传染性胸膜肺炎病猪体温升高,全身症状较重,剖检时有胸膜炎病变,猪气喘病则不然,体温不高,全身症状较轻,肺有肉样或胰样变区,而无胸膜炎病变。 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 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
