目的 掌握重庆市土源性线虫病流行动态和流行规律.方法 2006-2010年,每年9-12月在重庆市监测点采集年龄3周岁以上的全体常驻居民粪便,采用改良加藤厚涂片法(一粪三检)检查蛔虫、钩虫和鞭虫虫卵；3 ～ 12岁儿童加做透明胶纸肛拭法检测蛲虫虫卵；采集10户家庭的菜园、庭院、厨房及厕所周边的土壤样本,每份30 g,镜检土壤样本中受精和未受精的蛔虫虫卵,土壤培养法区分受精蛔虫卵活性.结果 重庆市监测点5年共累计调查5 071人次,2006-2010年,土源性线虫感染率依次为5.79％、13.52％、16.63％ 、8.62％和2.81％.人群总体土源性线虫感染率呈下降趋势(x2=3.65,P＜ 0.01).2007年及2008年女性感染率高于男性(x2=4.66,P＜ 0.05;x2=25.29,P＜ 0.01).2006及2010年5岁组感染率最高,2007及2008年60岁及以上组感染率最高,2009年50岁组感染率最高.蛔虫和钩虫是监测点感染的主要虫种,蛔虫感染以轻度为主,钩虫感染全部为轻度感染.各年男女生蛲虫感染率差异无统计学意义,女生蛲虫感染率总体上呈下降趋势(x2=16.36,P＜0.01),男生蛲虫感染率差异无统计学意义(x2=8.45,P＞0.05).土壤人蛔虫虫卵检出率分别为52.5％、37.5％、17.5％、30.0％和20.0％.检出率总体呈下降趋势(x2=14.97,P＜ 0.01).结论 重庆市监测点人群土源性线虫感染率总体上呈低水平,但仍应继续加强健康教育及集体驱虫等防治措施.
目的 掌握重慶市土源性線蟲病流行動態和流行規律.方法 2006-2010年,每年9-12月在重慶市鑑測點採集年齡3週歲以上的全體常駐居民糞便,採用改良加籐厚塗片法(一糞三檢)檢查蛔蟲、鉤蟲和鞭蟲蟲卵；3 ～ 12歲兒童加做透明膠紙肛拭法檢測蟯蟲蟲卵；採集10戶傢庭的菜園、庭院、廚房及廁所週邊的土壤樣本,每份30 g,鏡檢土壤樣本中受精和未受精的蛔蟲蟲卵,土壤培養法區分受精蛔蟲卵活性.結果 重慶市鑑測點5年共纍計調查5 071人次,2006-2010年,土源性線蟲感染率依次為5.79％、13.52％、16.63％ 、8.62％和2.81％.人群總體土源性線蟲感染率呈下降趨勢(x2=3.65,P＜ 0.01).2007年及2008年女性感染率高于男性(x2=4.66,P＜ 0.05;x2=25.29,P＜ 0.01).2006及2010年5歲組感染率最高,2007及2008年60歲及以上組感染率最高,2009年50歲組感染率最高.蛔蟲和鉤蟲是鑑測點感染的主要蟲種,蛔蟲感染以輕度為主,鉤蟲感染全部為輕度感染.各年男女生蟯蟲感染率差異無統計學意義,女生蟯蟲感染率總體上呈下降趨勢(x2=16.36,P＜0.01),男生蟯蟲感染率差異無統計學意義(x2=8.45,P＞0.05).土壤人蛔蟲蟲卵檢齣率分彆為52.5％、37.5％、17.5％、30.0％和20.0％.檢齣率總體呈下降趨勢(x2=14.97,P＜ 0.01).結論 重慶市鑑測點人群土源性線蟲感染率總體上呈低水平,但仍應繼續加彊健康教育及集體驅蟲等防治措施.

Objective To understand infection status and epidemic law of soil-transmitted nematode infections in Chongqing.Methods The stool samples of the residents at monitoring spot of Chongqing were collected and examined for Ascaris lumbricoides,Trichuris trichiura and hookworms with modified Kato-Katz thick smear "one stool specimen-three slides" from September to November during 2006-2010,and adhesive cellophane anal swab method was applied additionally for examining the eggs of Enterobius vermicularis in children aged 3-12.Ten soil samples were collected for microscopic examination on fertilized or unfertilized Ascaris eggs and the living ability of fertilized Ascaris eggs was determined.Results The total of 5 071 persons were investigated from 2006 to 2010 and the annual infection rates were 5.79％,13.52％,16.63％,8.62％and 2.81％ showing a declined tendency (x2=3.65,P ＜ 0.01).The infection rates of females were higher than males in 2007 and 2008 (x2=4.66,P ＜ 0.05;x2 =25.29,P ＜ 0.01).The infection rate of 5-year-old was in the highest level in 2006 and 2010.In 2010 the infection rate of 50-year-old was in the highest level.The ancylostomiasis and Ascaris were the major soil transmitted nematode diseases.The infection rates of Enterobius vermicularis were not significantly different between boys and girls.It showed a declined tendency in pinworm infection in girls(x2=16.36,P ＜ 0.01)while it showed no difference in boys(x2=8.45,P ＞ 0.05).The positive rates of Ascaris eggs in soil samples were 52.5％,37.5％,17.5％,30.0％ and 20.0％ showing a declined tendency (x2 =16.36,P ＜ 0.01).Conclusion According to the 5 years monitoring,the infection rate of soil-transmitted nematodes was declined,but health education and mass chemotherapy should be enhanced continuously.
