福建省清流县2013年土源性线虫病现状调查

目的 了解清流县土源性线虫病的现状及分布特点,为制定防治策略与措施提供科学依据. 方法 随机抽取福建省清流县长校镇、赖坊乡、龙津镇、嵩口镇、林畲乡共5个乡（镇）为调查点,收集粪便,采用改良加藤厚涂片法（一粪三检）检测蛔虫、鞭虫、钩虫等虫卵.用Microsoft Excel 2003软件建立数据库,用SPSS19.0软件对数据进行x2分析,P＜0.05为差异有统计学意义. 结果 共调查1 000人,土源性线虫感染76人,感染率为7.60％.钩虫、鞭虫和蛔虫感染率分别为7.60％、0和0.钩虫感染者克粪虫卵数（eggs per gram feces,EPG）最多的为320,最少的为2,均为轻度感染.感染率最高的为长校镇,为14.08％ （20/142）;最低的为林畲乡,为4.59％ （10/218）.男、女感染率差异无统计学意义（χ^2=0.043,P＞0.05）.不同年龄组间、不同文化程度人群、不同职业人群感染率差异均有统计学意义（χ^2=44.680、29.223、27.672,P＜0.01）. 结论 清流县土源性线虫病人群感染情况处于较低水平,年龄偏大、文化程度低、从事农业生产的人群仍是感染土源线虫的重点人群.

Investigation on the infection of soil-transmitted nematodes at Qingliu County,Fujian Province in 2013

Objective To understand the status and distribution characteristics of soil transmitted nema tode disease at Qinliu County,and to provide scientific basis for the prevention and control strategies and measures.Methods A random sample of Changxiao,Laifang,Longjin,Linyu and Songkou town,in Qingliu County,Fujian Province was choosed as the spots for the survey.Feces were collected and detected for the eggs of Ascaris lumbricoides,Trichuris trichiura,and hookworm,using modified Kato-Katz thick smear method.The database was established with Microsoft Excel 2003 software.The data were analyzed with SPSS19.0 software.The difference was statistically significant when P〈0.05.Results A total of 76 people was found infected with soil transmitted nematodes in 1 000 people investigated,the infection rate was 7.60%.The infection rates of hookworm,Trichuris trichiura and Ascaris were 7.60%,0 and 0 respectively.The hookworm eggs per gram feces（EPG） in the infected individuals was up to 320 while the least was 2,all at a mild infection level.The highest infection rate was 14.08% （20/142） at Changxiao Town; the lowest was 4.59% （10/218） at Linyu Town.The infection rate had no significant difference between male and female （χ^2=0.043,P〉0.05）.The infection rates were different with statistical significance among different age groups,education groups and occupation groups （χ^2=44.680,29.223,27.672,P〈0.01）.Conclusion The infection of soil-transmitted nematodes is at a low level in Qingliu County.The elderly,the people with low education level and the people engaged in agricultural production are the key population of infection of soil-transmitted nematodes.
