A study was conducted in southern Sudan to determine the prevalence of intestinal parasites among school children. A total of 275 stool samples which were examined using formol-ether concentration techniques yielded 15 different species of parasites. Hook worm with a prevalence of 13.1% was the predominant nematode followed by Strongyloides stercoralis (3.3%), Trichostrongylus (2.5%), Schistosoma mansoni (2.2%) and Trichuris trichiura (1.8%). Ascaris lumbricoides and cestodes were not detected in this population. Intestinal protozoans were common. Entamoeba coli (37.8%), Entamoeba histolytica (28.4%) and Giardia lamblia (9.8%). Children in the age group 6-10 years old were the most affected followed by the 11-15 year-old age group. The infection rate was slightly higher in males than females.
在苏丹南部开展了一项研究，以确定学童肠道寄生虫的流行情况。共采集了275份粪便样本，采用甲醛乙醚浓缩技术进行检测，发现了15种不同的寄生虫。钩虫感染率为13.1%，是主要的线虫，其次是粪类圆线虫（3.3%）、毛圆线虫（2.5%）、曼氏血吸虫（2.2%）和鞭虫（1.8%）。该人群未检测到蛔虫和绦虫。肠道原生动物较为常见。结肠内阿米巴（37.8%）、溶组织内阿米巴（28.4%）和蓝氏贾第鞭毛虫（9.8%）。6至10岁年龄组的儿童受影响最大，其次是11至15岁年龄组。男性的感染率略高于女性。
