Enterocytozoon bieneusi is a zoonotic pathogen of the phylum Microspora that infects humans as well as a variety of animal species worldwide.While molecular epidemiologic studies have characterized this parasite in various hosts,isolates from many susceptible hosts have not yet been examined.This experiment was conducted to study Enterocytozoon bieneusi genotypes in Pere Davids deer(Elaphurus davidianus)in Henan,China.In this study,E.bieneusi was isolated from 47 Pere Davids deer(Elaphurus davidianus)in Henan,China and characterized via PCR analysis of the internal transcribed spacer(ITS)gene.E.bieneusi was detected in 16 out of 47(34.0%)fecal specimens examined.Sequence analysis of the ITS revealed six known genoty pes: Type Ⅳ(4),EbpC(4),EbpA(4),BEB6(2),COS-Ⅰ(1),and COS-Ⅱ(1).Of these,Type Ⅳ,EbpC,and EbpA are known to cause human microsporidiosis worldwide,whereas the remaining genotypes are generally specific to ruminants.The present study indicated that Pere Davids deer are naturally infected with E.bieneusi,predominantly with zoonotic genotypes,and may pose a risk for human transmission.

吉林省松原地区位于松嫩平原，为了解牛瑟氏泰勒虫病在松原地区的流行情况，本研究采用SYBR Green PCR方法对松原地区2个规模化养牛场共39份血液样本进行检查，发现5份为牛瑟氏泰勒虫阳性样本，感染率为12.8％.不同年龄段牛瑟氏泰勒虫感染率差异不显著(P＞0.05)，不同养殖方式牛瑟氏泰勒虫感染率差异显著(P＜0.01)，放牧饲养的牛感染率显著高于圈养牛.
羊巴贝斯虫病是以绵羊巴贝斯虫(Babesia ovis)，莫氏巴贝斯虫(B.motasi)和粗糙巴贝斯虫(B.crassa)为主要病原因子，主要分布在热带和亚热带地区的血液原虫病.临床反应通常以高热，溶血性贫血，黄疸，血红蛋白尿为主要特征，严重时引起死亡.在宿主的红细胞内进行无性繁殖，有性繁殖发生在传播媒介蜱体内，并通过蜱的叮咬传播到宿主体内，因此巴贝斯虫的分布与其传播媒介-蜱的分布范围相一致.巴
热休克蛋白90(Heat shock protein 90,HSP90)是活化参与病原转化细胞发育和进程的许多信号转导蛋白分子不可或缺的分子伴侣,本研究通过筛选cDNA文库、快速扩增cDNA末端(RACE)和PCR扩增等方法,从感染我国羊的莫氏巴贝斯虫临潭株(Babesia motasi Lintan)体内克隆获得一个2399bp的热休克蛋白90的家族成员BQHsp90基因,其完整开放阅读框为21

在非人灵长类动物中,所感染的环孢子虫虫种与感染人的主要虫种卡耶塔环孢子虫(Cyclospora cayetanensis)亲缘关系最为相近,而卡耶塔环孢子虫曾在北美造成多起环孢子虫病暴发.目前研究表明环孢子虫的虫种可能存在一定的宿主特异性.本研究通过对SSU rRNA(small subunit rRNA)基因的序列分析,对采自于自由放养猕猴(Macaca mulatta)的411个粪样进行了环孢
