兰氏贾第虫为常见人体寄生原虫,国内各地调查的结果证明在儿童或青少年中感染较为普遍。内蒙地区中小学生感染兰氏贾第虫滋养及带囊率分别为0.1％和1.37％;包头学龄前儿童感染率为5％。为了进一步提高检出率,现将改进的病原检验方法介绍如下: 一般常规粪检法检出率较低,因为兰氏贾第虫有嵌附及侵入肠粘膜的特点,不易落入肠腔;又因繁殖旺盛不易成囊,故难于检出。十二指肠抽出液检查,可发现滋养体,但此法操作应具熟练技术,对患者有一定的痛苦。儿童不易配合。改进的拉纲法或尼龙线提取法,也有一定的难度及缺点,因此影响了诊断及治疗。
Giardia lamblia is a common human parasitic protozoan, the results of surveys around the country prove that infection in children or adolescents is more common. Inner Mongolia primary and secondary infection Giardia lamblia infection and the bandage rates were 0.1% and 1.37%; Baotou preschool children’s infection rate was 5%. In order to further improve the detection rate, the improved pathogen detection methods are introduced as follows: The detection rate of the conventional routine feces test method is low, because Giardia lamblia has the characteristics of invasion and adhesion to the intestinal mucosa and is hard to fall into the intestinal lumen; Because of the proliferation of hard-packed, it is difficult to detect. Duodenal extract examination can be found trophozoites, but this method should be skilled operation of the patient has some pain. Children are not easy to cooperate. Improved suture method or nylon line extraction method, there are certain difficulties and shortcomings, thus affecting the diagnosis and treatment.
