Abstract:

The parasitic eggs of stools of residents aged 6-65 years were detected with the Kato?Katz technique in Fusheng
Village of Poyang Lake area in Jiangxi Province in 2008. Results In 2008，the total average infection rate of soil?transmitted nem?
atodes was 37.97%，and the infection rates of Ascarid lumbricoid，Trichuris trichiura and hookworm were 20.39%，6.67% and
18.45%，respectively. The total infection rate of soil?transmitted nematodes and the rate of A. lumbricoid were higher in the female
than in the male with a statistically significant difference（P < 0.01）. The infection rates of T. trichiura and hookworm in the fe?
male were higher than those in the male，but there was no significant difference between them（P > 0.05）. The total infection rate
of soil?transmitted nematodes and the rate of hookworm in different age groups had a similar change pattern which had an increas?
ing trend with the age growing. The infection rate of A. lumbricoid was the lowest in the age group of 10-19 years and was the high?
est in the age group of 20-29 years，and then the rate showed a gradually declining trend with the age increasing. The infection
rate of T. trichiura had a decreasing trend as the age grew with 2 peaks in the age groups of 10-19 and 40-49，respectively. Con?
clusions The infection rates of soil?transmitted nematodes in population of Fusheng Village in Jiangxi Province are still high. The
effective control measures include health education，regular anthelminthic treatment，innoxiously processing of stool and environ?
ment reform，and the interruption of the transmitting chain is the fundamental strategy.

摘要：

目的 了解江西省鄱阳湖区居民土源性线虫感染状况。方法 于2008年对鄱阳湖区南昌县富盛村6~65岁居民采用Kato?Katz法检查蛔虫、鞭虫和钩虫感染情况，同时记录其他寄生虫卵。结果 2008年富盛村人群土源性线虫总平均感染率为37.97%，其中蛔虫、鞭虫和钩虫单虫种平均感染率分别为20.39%、6.67%和18.45%。女性居民土源性线虫和蛔虫感染率均高于男性，差异均有统计学意义（P < 0.01）；女性居民鞭虫和钩虫感染率亦高于男性，但差异无统计学意义（P >0.05）。不同年龄组人群土源性线虫与钩虫感染率变化规律相似，均随年龄增长而呈现升高趋势；蛔虫感染率10~19岁年龄组最低，20~29岁年龄组最高，而后随着年龄增大总体呈逐渐下降趋势；鞭虫感染率随年龄增加总体呈下降趋势，在10~19、40~49岁年龄组出现2个波峰。 结论 富盛村人群土源性线虫感染率较高，健康教育、定期驱虫和粪便无害化处理、环境改造是控制土源性线虫感染的有效手段。在治疗土源性线虫病患者控制传染源的同时，切断传播链不失为治本之策。
