Methods The residents and primary and secondary school students aged above 6 years in Tongshan Township,Jiangning District were selected as investigation objectives,and the Kato-Katz technique was used to detect the intestinal nematode eggs in feces of them. Results Four hundred and ten villagers were detected,and the infection rates of Ascaris lumbricoides and hookworm were 5.12% and 0.98%,respectively. Meanwhile,407 students were detected,and the infection rates of Ascaris lumbricoides and Fasciolopsis buski were 1.72% and 0.25%,respectively. The infection rates of intestinal nematodes in villagers and students were 6.10% and 1.97%,respectively, and the difference between them were statistically significant（ χ 2 =8.997,P 〈0.05）. Conclusions The infection rate of intestinal nematodes in rural population of Jiangning District,Nanjing City has decreased obviously,and the rate is higher in villagers than in students.
