【摘要】 目的 :了解福建、江苏农村土源性线虫的传播途径。方法 :样本经水洗沉淀 ,用直接涂片法检查幼虫 ,用消化法和饱和硝酸钠漂浮法检查土壤中虫卵。结果 :检查福建省邵武市 3个农村 18户农家的 16种蔬菜 ,其中 7种发现蛔虫卵钩虫丝状蚴与粪类圆线虫丝状蚴。 4 7份标本中有 19份阳性 ,检出率为 4 0 .4 % ,其中以大蒜、葱、卷心菜、空心菜检出率较高 ;江苏省江宁县 2个农村 2 0户农家 17种蔬菜中 ,11种发现虫卵 (蛔虫、钩虫、鞭虫 )和或小杆属线虫幼虫 ,79份标本中 2 1份阳性 ,检出率为 2 6.6% ,其中青菜、空心菜、苋菜检出率较高。菜场的蔬菜邵武市查 7种 ,4种 (葱、小白菜、香菜、黄瓜 )阳性 (蛔虫卵和 /或类圆线虫丝状蚴 ) ;江宁县查 9种蔬菜 ,4种 (萝卜、葱、西红柿、地瓜 )阳性 (蛔虫和 /或类圆线虫丝状蚴 )。农户鞋底土的虫卵检出率以福建邵武为高 55.6% ,江宁仅15.0 % (蛔虫卵 )。两村查到蛔虫卵、钩虫卵、鞭虫卵和犬弓蛔虫卵。结论 :被虫卵污染的蔬菜与鞋底土在土源性线虫传播上起相当作用。更多还原

【Abstract】 AIM:To understand the transmission route of soil- transmitted helminth in the villages of Fujian and Jiangsu Provinces. METHODS:Soil samples were washed with water and the sedimented larvae were examined by directsmear method. Eggs were examined after separat- ed from soil by floating with saturated sodium nitrate solution.RESULTS:Out of 1 6 kinds of vegatables collected from 1 8households in 3villages in Shaowu County,Fuian Province,7 kinds were found to have the eggs and/or larvae of Ascaris and other soil- transmitted helminths.1 9samples from47samples were positive,the positive rate being40 .4% .Among them.garlic,onion,cabbage and water spinach were found to have higher detection rate.Of 1 7kinds of vegetables collected from2 0 households in2 villages in Jiangning County,Jiangsu Province,1 1 kinds were found to have eggs of Ascaris and Rhabditis larvae.2 1 samples from 79samples were egg positive,the positive rate being2 6 .6 % .Green vegetable,water spinach and three- coloured amaranth had a higher positive rate. 4kinds of vegetables(onion,pak- choi,coriander and cucumber) among7kinds bought from the market in Shaowu County, were egg positive.In Jiangning County,4kinds(radish,onion,tomato and yam bean) from9 kinds were positive(Al and/or S.) .The egg positive rate of the shoe- sole soil samples in Shaowu County,Fujian Province(5 5 .6 % ) was higher than that in Jiangning County,Jiangsu Province(1 5 . 0 % ) . Ascaris lumbricoides,hookworm,Trichostrongylus and Toxocara canis were found in both places.CONCLUSION:The vegetables shoe- sole soil contaminated with helminth eggs and larvae played a role in the dissemination of soil- transmitted helminths.更多还原
