牛瑟氏泰勒虫病是一种广泛分布于世界各地的蜱传性原虫病,感染该病的牛常常会成为病原体的携带者,直接影响牛的健康发育和牛类产品的产量与质量.自然生境中的蜱是牛瑟氏泰勒虫的传播媒介.为了解吉林省东部山区蜱的种类及其携带牛瑟氏泰勒虫的情况,本研究采用布旗法在延吉市、龙井市、珲春市,3个市6个调查位点的自然生境内采集了280只蜱游离蜱类样本的采集并保存70%乙醇中,显微镜下依据经典蜱类形态学种属鉴定蜱的种类

牛瑟氏泰勒虫病是一种广泛分布于世界各地的蜱传性原虫病,感染该病的牛常常会成为病原体的携带者,直接影响牛的健康发育和牛类产品的产量与质量.自然生境中的蜱是牛瑟氏泰勒虫的传播媒介.为了解吉林省东部山区蜱的种类及其携带牛瑟氏泰勒虫的情况,本研究采用布旗法在延吉市、龙井市、珲春市,3个市6个调查位点的自然生境内采集了280只蜱游离蜱类样本的采集并保存70%乙醇中,显微镜下依据经典蜱类形态学种属鉴定蜱的种类,并以牛瑟氏泰勒虫MPSP基因为靶基因,采用PCR方法对吉林省东部山区不同种类蜱DNA进行了牛瑟氏泰勒虫的检测.结果表明本研究所采集到蜱隶属2属2种,其中长角血蜱占94.6%、全沟硬蜱占5.4%.说明吉林省东部山区自然生境内主要以长角血蜱和全沟硬蜱为主,长角血蜱是优势蜱.在长角血蜱的DNA中检测了牛瑟氏泰勒虫,而全沟硬蜱中没有检测到牛瑟氏泰勒虫,表明长角血蜱是传播牛瑟氏泰勒虫的媒介蜱.

残缘璃眼蜱属于专性外吸血寄生虫,能够传播多种病原体,特别是对环形泰勒虫的传播给畜牧业造成较大的损失。目前蜱的防治越来越多的应用免疫方法,但对残缘璃眼蜱防治的研究较少,同时对媒介蜱传播环形泰勒虫的防控过程研究基本没有;因此,本试验通过对残缘璃眼蜱中肠、唾液腺中的活性分子研究,以期筛选出有效的控蜱及蜱传病候选抗原。本研究以残缘璃眼蜱饥饿成蜱为模板,cys500为引物扩增得到半胱氨酸蛋白酶(Cystei
现已发现苍溪有嗜群血蜱(Haemaphysalis concinna Koch,1844)、长角血蜱(Haemaphysalis longicomis)两种.为了解血蜱在苍溪县的分布、危害、季节活动规律及一些生物学特性.采用宿主体检蜱法、拖旗法、布旗覆盖法采集动物体表和野外环境的蜱,并进行形态鉴定和药物等防制试验.结果显示:1、在2005年,苍溪县发生嗜群血蜱暴发性疫情,流行面达97.4%,动物感
