摘要
目的了解南昌市农村地区人群土源性线虫感染状况,掌握流行规律。方法对2016-2022年南昌市农村地区3周岁及以上常住居民的粪便采用改良加藤厚涂片法(一粪两检)开展土源性线虫检测,采用试管滤纸培养法鉴定钩虫卵阳性粪样的钩虫种类,统计感染率及其感染程度,使用卡方检验进行比较分析。结果2016-2022年土源性线虫总感染率为1.29%(280/21783),各年感染率依次为1.11%(46/4157)、1.40%(57/4062)、1.33%(55/4126)、1.13%(46/4077)、0.73%(13/1773)、2.39%(43/1797)和1.12%(20/1791),各年度感染率比较差异有统计学意义(χ^(2)=24.391,P<0.01)。88.93%(249/280)感染者为轻度感染。钩虫、蛔虫和鞭虫感染率分别为0.98%(213/21783)、0.02%(5/21783)和0.30%(65/21783),不同虫种感染率差异有统计学意义(χ^(2)=244.053,P<0.01),混合感染样本有3份,均为钩虫和鞭虫混合。土源性线虫感染分布特征显示,不同地区、性别、年龄组和职业间感染率差异均有统计学意义(χ^(2)=223.950、39.614、98.125、52.739,P均<0.01),分别以安义县3.12%(168/5379)、女性1.77%(191/10789)、60~<70岁年龄组2.39%(92/3850)和农民1.61%(259/16080)感染率最高。钩虫为本次监测的优势虫种,尤其安义县钩虫感染人数占钩虫感染总人数的77.93%(166/213),蛔虫和鞭虫处于较低感染水平。结论南昌市农村地区人群土源性线虫感染率稍高,钩虫为优势虫种,尤其安义县钩虫感染率较高,应采取对应防控措施。
Objective To understand the prevalence of soil-transmitted nematodes(STN)infection in the population in rural areas of Nanchang,and grasp the epidemic patterns.Methods The modified Kato-Katz thick smear method(two tests for one stool sample)was used to detect soil-derived nematodes in the stool of permanent residents aged 3 years old and above in rural areas of Nanchang city from 2016 to 2022.The species of hookworm with positive stool samples of hookworm eggs were identified by the test tube filter paper culture method;the infection rate and infection degree were calculated,and the Chi-square test was used for comparative analysis.Results From 2016 to 2022,the total infection rate of STN was 1.29%(280/21 783);the annual infection rates were 1.11%(46/4 157),1.40%(57/4 062),1.33%(55/4 126),1.13%(46/4 077),0.73%(13/1 773),2.39%(43/1 797)and 1.12%(20/1 791),respectively.The infection rate of each year had significant difference(χ^(2)=24.391,P<0.01).88.93%(249/280)were mild infection.The infection rates of hookworm,Ascaris lumbricoides and Trichuris trichiura were 0.98%(213/21 783),0.02%(5/21 783),0.30%(65/21 783),respectively.The infection rate of different species was significantly different (χ^(2)=244.053,P<0.01).Mixed hookworm eggs and Trichuris trichiura eggs were found in 3 samples.The distribution characteristics of STN infection showed that there were significant differences in infection rates among different areas,sex,age groups and occupations (χ^(2)=223.950,39.614,98.125,52.739;all P<0.01).The highest infection rates were 3.12%(168/5 379)in Anyi county,1.77%(191/10 789)in females,2.39%(92/3 850)in 60-<70 years old age group and 1.61%(259/16 080)in farmers.Hookworm was the dominant species in this survey;hookworm infections accounted for 77.93%(166/213)in Anyi county.Ascaris lumbricoides and Trichuris trichiura were at a lower level of infection.Conclusions In rural areas of Nanchang,the infection rate of STN was maintained at a slightly high level.Hookworm was the dominant species,especially in Anyi cou
