摘　　要：本文报道滇西北怒江州傈僳、勒墨少数民族的寄生虫感染调查结果。两民族中共查出人体肠道寄生虫13种,含原虫7种,线虫5种,绦虫1种。多种感染十分普遍,一人同时感染3种以上寄生虫者分别为53.8％和61.4％。傈僳族和勒墨族的主要寄生虫感染率依次分别为:钩虫(包括N.a和A.d.)78.8％和60.2％,蛔虫71.2％和62.1％,鞭虫36.5％和74.5％,蛲虫6.2％(6/96)和54.8％(79/230),此外尚查见东方毛圆线虫0和0.2％,微小膜壳线虫0和0.2％,溶组织内阿米巴0.6％和0.9％,结肠内阿米巴7.9％和8.4％,哈氏内阿米巴5.4％和1.1％,微小内蜒阿米巴9.4％和7.7％,布氏嗜碘阿米巴4.0％和0,贾第虫6.3％和0.7％,人酵母菌30.4％和4.2％。During March to Aprill 1990, a total of 1065 local residents in Lisu and Leme minority areas were surveyed by fecal examination with iodine direct smear, modified Kato-Katz thick smear, adhesive tape techniques and fecal culture. The overall infection rate of the two minorities was 93.1% and 97.6%, respectively. Multiple infection was very common ; cases infected more than 3 species accounted for 53.3% in Lisu and 61.4% in Leme. A total of 13 species of intestinal parasites were detected from the two minority areas, demonstrating the infection rates as follows: Ascaris lumbricoides 81.9%, hookworn (N. a. :A. d. =5.6:1) 69.3%, Trichuris trichiura 55.9%, Enterobius vermicularis 34.3%, Trichostrongylus orientalis 0.1%, Hymeno-lepis nana 0.1%, Entamoeba histolytica 0.8%, E. coli 8.2% E. hartmanni 3.2%, Endo-limax nana 8.6%, lodamoeba buetschlii 1.9%, Giardia lamblia 3.5%, and Blastocystis hominis 16.9%. The hookworm infection rate was higher in Lisu than that in Leme, while that of other nematode infections was generally higher in the latter minority This difference is attributed to the diversity of socioeconomic and hygienic conditions between the two minorities in recent years.
