【摘要】 应用分层整群随机抽样方法,于1987～1990年进行了云南省人体寄生虫分布调查。共查28个县103个点,53061人,寄生虫感染率为76.3%。查到肠道寄生虫25种,包括线虫9种,绦虫5种,吸虫1种和原虫10种。感染1、2、3、4、5种寄生虫者分别占总感染人数的47.0%、33.7%、14.4%、3.7%和0.8%。主要致病虫种的感染率为:钩虫19.3%、蛔虫59.6%、鞭虫27.6%、蛲虫12.9%(儿童)、旋毛虫13.5%(血清免疫学试验阳性458/3392)、带绦虫0.93%、猪囊虫3.26%(106/3252,血清学阳性)、溶组织内阿米巴2.54%、蓝氏贾第鞭毛虫2.49%、芽囊原虫(人体酵母菌)6.98%。总感染率和钩虫、蛔虫、鞭虫的感染率在不同地区和不同性别、年龄、职业和民族之间均有显著性差异。更多还原

【Abstract】 103 pilot sites were selected from 28 couuties in Yunnan province via stratified and clusteredrandom sampling.Iodine direct smear,modified Kao—Katz thick smear,adhesive—tape techniques and fecalculture methods were applied for fecal examination.A total of 25 species of intestinal parasites were identi-fied from 103 sites,53 061 residents.The overall parasitic infection rate is 76.3%.The infection rates ofmajor pathogenic parasites were as follows:Hookworm 19.3%,Ascaris lumbricoides 59.0%,Trichuristrichiura 27.29%,Trichnella spiralis 13.5%(458/3 392,positive for serum),Enterobius vermicularis 12.9%(1426/11053),Tapworm 0.93%,Cysticercosis 3.26%(106/3 252,positive for serum),Entamoeba his-tolytica 2.54%,Ciadia lamblia 2.49%,Blastocystis hominis 6.98%.Multiple-infection is very common,cas-es infected more 2 species accounted for 53%,One case was up to 9 species of parasite.更多还原
