摘　　要：在湖南省衡山县４个村应用Ｋａｔｏ－Ｋａｔｚ法检查了１２０２人，蛔、鞭、钩虫的阳性率依次为６３．３％、４６．２％和６．８％，土源性线虫阳性卒为７１．０％。土壤样本检查，每户查７处（庭院、客堂、卧室、厨房、厕所、牲畜圈、鞋底），共查１１２户。１１２户中蛔虫卵阳性率６３．４％，鞭虫卵３６．６％，蛔虫卵和／或鞭虫卵阳性者６４．３％。经相关分析表明４个村人体鞭虫卵阳性率与土壤样本的鞭虫卵阳性率、人体土源性线虫阳性率与土壤样本蛔虫卵和／或鞭虫卵阳性率十分相关，相关系数分别为０．９８７（Ｐ＜０．０１）和０．９５４（Ｐ＜０．０５）。土壤样本蛔虫卵则以厕所（３８．３％）、庭院（３３．０２％）和鞋底（２３．４％）为多，鞭虫卵则以庭院（１５．２％）、鞋底（１４．９％）和牡畜圈（１１．６％）为多。此外，土壤样本中还查到其它寄生虫卵、卵囊或成虫。AbstractFour villages in Hengshan county,Hunan Province were selected as pilot areas.1292 per-sons were examined by Kato-Katz method. The Prevalence rates of ascaris ,whipworm ,hookworm and the total were 63.3%,46.2%,6.8%and 71.0%respectively.Soil samples were collected from 7 sites(courtyard,sitting room,bedroom,kitchen,la-trine,animal shed,shoe-bottoms)of each of 112 houses from the villages.The detection ratesof Ascaris eggs,Trichuris eggs,Ascaris eggs and Trichuris eggs were 63.4%, 36.6%and 64.3%respectively.High detection rates of ascaris eggs were found in soil samples of latrine(38.3%),courtyard(33.0%)and shoe-bottom(23.4%). High detection rates of whipworm eggs were in courtryard(15.2%),on shoe-bottoms(14.9%)and in animal sheds(11.6%).The statistical analysis indicates a highly significant correlation between the detection rate ofTrichuris eggs in soil and the prevalence of Trichuris infection,and between the detection rate ofAscaris eggs and/ or Trichuris eggs in soil and the prevalence of total STN infection, the r was0.987(P<0.01)and 0.954(P<0.05),respectively.In addition,eggs of Stronglyoides spp,Capillaria hepatica,Toxocara canis,Toxooaracati,Hymenolepis diminuta and Taenia spp , cysts of Balantidium coli,larvae and adults of u-nidentiified nematodes and mites were forund also.
