Large scale studies were performed to determine the prevalence of various intestinal helminth infections in urban and rural areas of Khuzestan Province, southwest Iran. A total of 16,361 stool samples from people in 105 villages and 14 small towns were examined by the formalin-ether concentration method. Ascaris, hookworms, Trichostrongylus, Trichuris, and Hymenolepis nana showed the highest prevalence. Hookworms and Trichostrongylus were twice as prevalent in rural than in urban areas; in contrast, H. nana was more prevalent in urban areas while the level of Ascaris infections was not significantly different. The intensity of Ascaris and hookworm infections, as estimated by the number of eggs/g of feces, was higher in rural than in urban areas.
开展了大规模研究，以确定伊朗西南部胡齐斯坦省城乡地区各种肠道蠕虫感染的流行情况。采用福尔马林-乙醚浓缩法对来自105个村庄和14个小镇的16361份粪便样本进行了检测。蛔虫、钩虫、毛圆线虫、鞭虫和微小膜壳绦虫的感染率最高。钩虫和毛圆线虫在农村地区的感染率是城市地区的两倍；相比之下，微小膜壳绦虫在城市地区更为普遍，而蛔虫感染水平在城乡之间没有显著差异。根据每克粪便中的虫卵数量估算，蛔虫和钩虫感染的强度在农村地区高于城市地区。
