【摘要】：贾第虫是一种人兽共患性寄生原虫,可在全世界范围内传播,并且有人—人,人—动物,以及动物特异性的传播循环,且其流行率与地理环境以及不同的区域有关。采用分子生物学分析方法,确定长春地区的宠物犬患有贾第虫的患病率以及基因型来评估犬贾第虫向人传播的危险。调查结果显示:宠物犬的贾第虫流行率为10.46%(25/239)。通过磷酸丙糖异构酶(TPI)基因的多态性对所分离虫株的基因型进行鉴定,结果显示所有贾第虫的基因型均为犬特异性的C型,未发现人兽共患的A型和B型。基因亚型结果显示在所有的样本中以CⅠ为主要亚型,占全部样本的76.00%(19/25)。此结果显示出贾第虫由犬传播给人的风险很低,这与以往来自中国南方的调查结果明显不同。
[Abstract]:Giardia is a zoonotic parasite that can spread around the world and has a human-human, human-animal, and animal-specific transmission cycle. And its prevalence is related to geographical environment and different regions. The prevalence and genotype of giardia in dogs in Changchun area were determined to evaluate the risk of transmission of giardia to humans. The prevalence rate of giardia in pet dogs was 10.46 to 25 / 239. The TPII gene was obtained by means of propyl phosphate isomerase. To identify the genotypes of the isolates, The results showed that all the giardia genotypes were canine-specific type C, and no zoonotic type A and B were found. The results of gene subtypes showed that C 鈪，
