淮南地区腹泻患者隐孢子虫感染的调查

An epidemiological survey of cryptosporidiosis with diarrhea in Huainan area

目的探讨淮南地区腹泻人群隐抱子虫的感染情况,为深入研究隐孢子虫病提供科学依据。方法采用金胺-酚+改良抗酸染色法对淮南地区部分腹泻人群的新鲜粪膜标本进行染色、镜检。结果淮南地区部分腹泻人群隐孢子虫感染率为5.6％(46/827),其中儿童为6.1％(45/735),成人1.1％(1/92);急性腹泻和慢性腹泻隐孢子虫感染率分别为4.5％(26/581)和 8.1％(20/246);男、女人群隐孢子虫感染率分别为5.2％(26/497)和6.1％(20/330)。结论淮南地区存在隐孢子虫病,婴幼儿为高发人群组,慢性腹泻患者感染率明显高于急性腹泻患者,男、女人群隐孢子虫感染率相近。

Objective In order to provide science bases for further research, the infection of Cryptosporidium parvum of some Cryptosporidiosis with diarrhea in huainan area were studied. Methods The oocyst of Cryptosporidium parvum in 827 fresh stool samples from Cryptosporidiosis with diarrhea in huainan was tested by auramine-phenol stain and modified acid-fast method. Results The total infection rate of Cryptosporidium parvum of some Cryptosporidiosis with diarrhea in huainan was 5.6%(46/827). Among them, the positive rates of oocyst in children, adults, patients with acute diarrhea, patients with chronic diarrhea, male, and female were 6.1%(45/735), 1.1%(1/92), 4.5%(26/581), 8.1%(20/246), 5.2%(26/497), and 6.1%(20/330) respectively. Conclusions There were Cryptosporidiosis in huainan, and the infection rate of Cryptosporidium parvum in children was higher, the positive rates of oocyst in patients with acute diarhea was significantly lower than those in chronic diarrhea. The positive rate of oocyst in male was similar to that in female.
