猪附红细胞体病是由猪附红细胞体引起猪的一种急性、热性、群发性传染病。临床上以发热、贫血、溶血性黄胆、呼吸困难、皮肤发红为主要特征。猪弓形虫病是由弓形虫寄生于猪细胞体内而引起的一种寄生性原虫病。 相似文献

附红细胞体与弓形体都是猪的血液寄生虫，发病后体温升高，皮肤发红，黄疸、贫血、怀孕母猪流产，最后耐过的幼猪可能有耳边干死症状，两种病都可导致猪胸、腹和心包积水、全身淋巴结肿大，这两种病在河北、山东等地不断发生，它们的症状容易混淆，但是其治疗药物又各不相同。治疗猪附红细胞体病的最好药物是血虫净。也可用阿散酸预防，治疗猪弓形虫的常用药物是磺胺，在治疗过程中，要确诊是附红细胞体引起的发病。还是弓形体引起的发病，或是两种病原共同作用的结果。 相似文献

猪附红细胞体病是由立克次氏体引起猪牛羊貂等动物的一种热性、溶血性疾病。表现为发热、贫血、黄疸、消化和呼吸功能障碍。仔猪患病后死亡率极高,常给养猪业生产造成重大损失,是近年来新发现的一种人畜共患病。1流行病学猪附红细胞病多由折光性较强的小附红细胞体引起发病,对由无折光性的大附红细胞体引起发病的较为少见。该病可经子宫、胎盘垂直传播,也可由虱、蚤、螨等吸血昆虫和被污染的注射器具(如针头等)水平传播。一年四季均可发生,以春季多发,气候突变,饲养不良,长途运输,患其它疫病,导致体质下降等原因,是本病诱因。该病侵害初生仔… 相似文献

附红细胞体病（Eperythrozoonosis）是专性血液寄生虫～附红细胞体（Eperythrozoon）引起的一种人畜禽共患的血液传染病。弓浆虫病是由真球虫目、肉孢子虫科、弓形虫亚科、弓形虫属的弓浆虫，寄生猪细胞内引起的一种人畜共患血液原虫病。近年来两病混合感染在大别山区中小型养猪场的猪群中不断发生和流行，临床主要症状：高热、呼吸困难、尿液发黄，身上有出血点，耳朵水肿发紫类似猪瘟及蓝耳病症状。我们根据流行病学、剖检病理变化、实验室检验诊断为弓浆虫和附红细胞体混合感染引起猪体发病和死亡。我们用中西药物结合治疗，收到满意效果。现将疾病诊治结果和预防措施报告如下： 相似文献

<正> 猪弓形体病是由龚地弓形虫引起的一种传染性很强的急性原虫病;猪附红细胞体病是由猪嗜血性支原体——附红细胞体寄生于猪血液中的红细胞表面或血浆中而引起一种危害极大的传染性寄生虫病。两者都是近几年广泛流行的人畜共患传染性寄生虫病,均以8～10月间的高温季节较为多见,两者都有高热稽留(40.5℃～42℃)、皮肤变色等相同症状,临床上很容易混淆,要注意鉴别。在传播途径上,猪弓形体病是猫;而猪附红细胞体病是蚊蝇或胎盘垂址传播。在发病年龄上,猪弓形体病多发于50～100千克的猪;而猪附红细胞体病多发于20～40千克的小架子猪。在症状上,猪弓形体病有明显的呼吸道症状,后期呼吸高度困难,体表淋巴结和腹股沟淋巴结明显肿大;猪附红细胞体病有贫血、轻微黄疸症状。在病理剖检上,弓形体病 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 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 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 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 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
