To estimate the prevalence and public health significance of cryptosporidiosis in goats in China,1265 fecal samples from seven farms in Henan province and Chongqing city were examined for Cryptosporidium oocysts.The overall infection rate of Cryptosporidium was 3.48% (44/1256).Significant difference was observed among age groups,with the postweaned kids having the highest infection rate (4.58%; x 2=14.23,ρ < 0.01).Cryptosporidium spp.were characterized by PCR:restriction fragment length polymorphism (RFLP) analysis and DNA sequence analysis of the small subunit (SSU) rRNA gene.The SSU rRNA:based PCR identified three Cryptosporidium species,including C.ubiquitum (24/44) in Henan province and Chongqing city,and C.andersoni (16/44) and C.xiaoi (4/44) in Henan province.Cryptosporidium ubiquitum was found in all age groups,C.Andersoni in all age groups except for the postparturition nannies,and C.xiaoi in prE-weaned kids and pregnant nannies.Thus,these findings indicate goats are a potential source for zoonotic infections with the C.ubiquitum.More studies are needed for better understanding of differences in the transmission and public health significance of cryptosporidiosis in goats.

课题组采用454测序技术对美国一豪猪源的泛在隐孢子虫分离株进行了全基因组测序,与已经测序的微小和人隐孢子虫的基因组相比,三者在编码区的序列同源性要远高于在非编码区的序列同源性.尽管泛在隐孢子虫在基因排列上与微小和人隐孢子虫呈现近乎完全一致的共线性,但在该基因组内还是存在一些大的插入和缺失.进一步在泛在隐孢子虫基因组中发现了gp60位点序列,并建立了基于该位点的PCR-测序方法,用于泛在隐孢子虫的亚
Cryptosporidium hominis is the dominant species responsible for human cryptosporidiosis.Within the species,one subtype at the gp60 locus,IbA 10G2,is the most virulent parasite,responsible for all C.Ho
为了探究贝氏隐孢子虫在禽类体内感染移行方式与寄生部位的关系,本课题组先后通过4次独立的7-12日龄雏鸡感染试验表明,直接嗉囊接种贝氏隐孢子虫卵囊的雏鸡随粪便排出大量卵囊,黏膜改良抗酸染色和组织切片结果显示,只能在法氏囊黏膜表面发现隐孢子虫特征性虫体；扫描电镜观察发现在法氏囊黏膜上寄生有大量隐孢子虫虫体,在气管和支气管黏膜上仅发现零星少量虫体；滴口或饮水感染卵囊的雏鸡组也得到相同结果.经直肠接种子孢

本研究从上海、南京、武汉和青岛四个城市的生活污水处理厂采集了未经处理的生活污水样本,采用PCR-测序的分型方法,研究了样本中人兽共患的隐孢子虫虫种、蓝氏贾第虫和比氏肠微孢子虫在基因型和亚型水平上的分布特征.为了阐明动物宿主对这些病原体的贡献,也对只感染动物的艾美尔球虫进行了基因分型.在386份样本中,隐孢子虫、贾第虫、微孢子虫和艾美尔球虫的阳性率分别达到56.2％、82.6％、87.6％和80.3
本研究克隆微小隐孢子虫粘附相关ep966基因,制备了ep966重组乳酸杆菌口服疫苗,观察了ep966重组乳酸杆菌口服疫苗对小鼠免疫的效果,评价了其对犊牛的免疫保护作用.结果表明:cp966与GeneB-ank上预测的假定蛋白cgd4_4110基因序列的一致性达99.90％,蛋白质的序列一致性为100％,该蛋白定位在微小隐孢子虫子孢子膜上；利用cp966胞外区片段构建植物乳酸杆菌工程菌,口服免疫小鼠
本研究收集了683名接受抗病毒免费治疗项目的河南HIV阳性患者(病例组)和683名人口信息与病例组匹配的当地健康人群(对照组)的粪便样本,并通过PCR和测序等分子生物学技术对隐孢子虫的虫种和基因亚型以及比氏肠微孢子虫的基因型进行了检测和区分.结果显示在HIV阳性患者和正常人群中,隐孢子虫的感染率分别为1.5％和0.15％,比氏肠微孢子虫的感染率分别为5.7％和4.2％.大多数的隐孢子虫感染病例(8
经饮用水是感染隐孢子虫病的最重要途径之一.本研究对我国33个重要城市66座自来水厂原水中隐孢子虫的浓度进行了调查,在此基础上综合考虑隐孢子虫活性、水厂处理工艺、饮用水摄入途径、人群免疫状况等因素对我国水源性隐孢子虫病的健康风险进行了定量评价.结果表明:我国自来水厂原水中隐孢子虫浓度为0-6卵囊/10L,平均为0.7卵囊/10L;经饮用水途径感染隐孢子虫的年感染率在免疫缺陷人群为2701/10万,免
