为了解金华地区奶牛结肠小袋纤毛虫的感染情况,采用廖党金的方法通过对不同规模奶牛养殖场(户)中随机选择的215头奶牛粪便进行检测。结果显示金华地区奶牛结肠小袋纤毛虫场感染率达100%,奶牛平均感染率为63.26%,平均EPG值在96～442之间。其中青年牛的感染率为最高,达78.13%,在被调查的寄生虫阳性的青年牛中小袋纤毛虫为100%感染。结肠小袋纤毛虫已成为金华地区奶牛感染的优势虫种,应引起重视并进行针对性的驱虫治疗。 相似文献

为了解郴州感染猪小袋纤毛虫的情况,对郴州六个县的猪场采集的猪粪便进行直接涂片和水洗沉淀镜检鉴定,统计感染率。结果显示,郴州六个县采样中结肠小袋纤毛虫的感染率为21.5%~35.0%。其中,桂东县的结肠小袋纤毛虫的感染率最高为35.0%,永兴县的结肠小袋纤毛虫的感染率最低为21.5%。通过ITS基因对小袋纤毛虫进行PCR鉴定,与NCBI网站上的结肠小袋纤毛虫ITS序列(AM982727和AM982726)同源性很高,为98%。 相似文献

正结肠小袋纤毛虫(Balantidium coli)首先由Malmsten(1857)从瑞典两例急性痢疾病人的粪便中发现,定名为结肠草履虫(Paramecium coli)。之后,Leukart(1861)在猪的大肠中也有发现。Stein(1863)认为前两人所见为同一种,更名为Balantidium coli~([1-2])。已知有30多种动物能感染结肠小袋纤毛虫,感染之后可引起宿主腹泻,其中猪的感染率可达60%～70%,是最主要的传染源~([3])。1病原1.1形态结肠小袋纤毛虫属于纤毛虫纲、毛口目、小袋 相似文献

<正>结肠小袋纤毛虫是猪场常见寄生原虫。对屠宰猪结肠黏膜调查发现,结肠小袋纤毛虫在猪群中的感染率近乎100%。本文将结肠小袋纤毛虫在猪体内的致病过程结合不同规模猪场的特点来分析其发病率不同的原因,以期对广大散养户正确防控结肠小袋纤毛虫病有所帮助。 相似文献

猪结肠小袋纤毛虫病是由猪的结肠小袋纤维虫(又名猪结肠小袋纤毛虫或猪小袋虫)引起的一种传染病,该病不仅会引起并发症,传染源进入人体后还会导致人体感染,引发相关症状,例如顽固性腹泻的出现。该病分布较广,不仅阻碍养猪业的蓬勃发展,对人类的健康也造成了一定的威胁,不得不引起我们的重视。本文就猪结肠小袋纤毛虫病的发病原理、临床症状、病原学等几个方面阐述该病的诊断及防治措施,为相关产业提供参考。 相似文献

猪结肠小袋纤毛虫病是由结肠小袋纤毛虫寄生于猪结肠所引起的一类人畜共患原虫病。该病主要引起断奶仔猪表现出腹泻、脱水、消瘦及贫血等特征性的一系列临床症状。为了有效的防治以腹泻、脱水和消瘦为特征的猪结肠小袋纤毛虫病。根据临床症状、剖解所见的病理变化作出初步诊断。此外,采取分子生物学(PCR技术)方法对该病作出确诊,确诊该病病原为猪结肠小袋纤毛虫。针对该病原体的特性,我们采用甲硝唑+驱虫净配伍方式对病猪进行治疗。结果显示大部分病猪痊愈,治愈率为99.2%。 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
