A Parasitology survey was conducted in Sagbama Community of the Niger Delta to determine the pattern of infection of intestinal parasites of man. 280 faecal samples were collected from randomly selected individuals and examined microscopically for ova, larvae and cysts of intestinal parasites. The overall infection rate was 33.6%. The frequency of the parasites encountered was as follows: Ascaris lumbricoides (18.2%). Entamoeba histolytica (6.4%). Hookworm (5.4%). Trichuris trichiura (3.5%), strongyloides stercoralis (3.5%), Schistosoma intercalatum (2.5%), Enterobius vermicularis (1.4%), Fasciola hepatic (0.7%) and Hymenolepis nana (0.4%). The rate of infection (41.1%) was highest in the 6--15 years old age bracket and lowest in the age group above 45 years. Prevalence rate of the males (37.1%) was statistically different from prevalence rate of the females (28.3%) at (P > 0.01). Percentage infection in relation to type of toilet facilities showed that the use of "Bush" as convenience carried the highest rate of parasitic infection (42.0%) followed by the use of stream/river (36.6%). Individuals who used pit, bucket and water closet as toilet facilities had infection rates of 27.7%, 20.9% and 15.5% respectively. Rate of infection in relation to source of drinking water showed that river/stream, wall/pond and pipe borne water had 35.9%, 32.8% and 12.5% respectively. The present study demonstrated that the type of toilet facilities and source of drinking water, among others, are important determinants of the level of parasitic infection in a rural village setting.
在尼日尔三角洲的萨格巴马社区开展了一项寄生虫学调查,以确定人类肠道寄生虫的感染模式。从随机挑选的个体中收集了280份粪便样本,并通过显微镜检查肠道寄生虫的虫卵、幼虫和囊肿。总体感染率为33.6%。所发现的寄生虫频率如下:蛔虫(18.2%)、溶组织内阿米巴(6.4%)、钩虫(5.4%)、鞭虫(3.5%)、粪类圆线虫(3.5%)、间插血吸虫(2.5%)、蛲虫(1.4%)、肝片吸虫(0.7%)和微小膜壳绦虫(0.4%)。感染率在6至15岁年龄组最高(41.1%),在45岁以上年龄组最低。男性患病率(37.1%)与女性患病率(28.3%)在统计学上存在差异(P>0.01)。与厕所设施类型相关的感染百分比表明,使用“灌木丛”作为便利设施的寄生虫感染率最高(42.0%),其次是使用溪流/河流(36.6%)。使用坑式、桶式和抽水马桶作为厕所设施的个体感染率分别为27.7%、20.9%和15.5%。与饮用水源相关的感染率表明,河流/溪流、墙壁/池塘和管道供水的感染率分别为35.9%、32.8%和12.5%。本研究表明,厕所设施类型和饮用水源等因素是乡村环境中寄生虫感染水平的重要决定因素。
