奶牛附红细胞体综合防治措施

附红细胞体病(Eperylhrozoon)是一种人畜共患病,病原体附着于红细胞表面和血浆中,在急性发病时,家畜出现黄疸、贫血和高热等症状,一般多为隐性感染,过去由于附红细胞体对人和动物感染的普遍性及临床发病的不显现性,没有引起人们的足够重视.但近年来,人和家畜附红细胞体病例的报道逐渐增多.现以试验为基础提出奶牛附红细胞体病的防治措施.……     

单抗捕捉ELISA检测猪附红细胞体血清抗体方法的建立

猪附红细胞体病是由附红细胞体(Eperythrozoon)寄生于多种动物和人红细胞表面、血浆和骨髓而引起的一种人畜共患病[1-2].本病自1928年发现以来被人们长期忽视,近年来随着人附红细胞体病病例的增多,家畜附红细胞体病的暴发流行,引起国内外学者的关注.本试验首次应用自主研制的猪附红细胞体单克隆抗体,初步建立了一种简便、经济、特异的单抗捕捉ELISA方法,用于检测猪附红细胞体的血清抗体,为诊断试剂盒的研制奠定了基础.

羊附红细胞体病防治

附红细胞体病(简称附红体病或血虫体病),是由附红细胞体附着在红细胞上或游离于血浆中,使机体发生以溶血性贫血为主的能够感染猪、牛、羊、鸡等多种家畜和人类的一种人畜共患传染病.该病主要呈隐性感染,可造成家畜体质衰弱,繁殖能力下降,饲料报酬降低,对养殖业的危害很大.

猪附红细胞体病的预防与控制

附红细胞体病是一种人畜共患病。附红细胞体寄生在猪、羊等家畜的红细胞表面或者血浆中,能够引起黄疸、贫血、高热等症状。猪附红细胞体病给我国养殖业造成了巨大的损失,笔者中,笔者从介绍猪附红细胞体病病原体入手,对该病的流行病学特点、临床症状进行了简单的介绍,并提出了几点预防和控制猪附红细胞体病的措施,以期为猪附红细胞体病的防治提供相应的根据。     

浅谈猪附红细胞体病的诊治

附红细胞体病属于一种寄生虫病,主要是指家畜血液中的血浆或红细胞表面存在附红细胞体,对猪的红细胞产生一定的破坏,导致血液中红细胞的数量不断减少,降低红细胞携氧功能.通常猪附红细胞体具有较强的低温抵抗力,对强力霉素和干燥敏感,在引种时要做好选育和饲养管理等工作,从而增强猪体抵抗力,有效预防附红细胞体病.本文就对猪附红细胞体病的诊治进行分析和探究.

Heartworm in dogs in Canada in 1984

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.
