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。47份标本中有19份阳性, 检出率为40.4%, 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20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21份阳性,检出率为26.6%, 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。

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 direct smear method. Eggs were examined after separated from soil by floating with saturated sodium nitrate solution. RESULTS: Out of 16 kinds of vegatables collected from 18 households in 3 villages in Shaowu County, Fujian Province, 7 kinds were found to have the eggs and/or larvae of Ascaris and other soil-transmitted helminths. 19 samples from 47 samples were positive, the positive rate being 40.4%. Among them, garlic, onion, cabbage and water spinach were found to have higher detection rate. Of 17 kinds of vegetables collected from 20 households in 2 villages in Jiangning County, Jiangsu Province, 11 kinds were found to have eggs of Asca ris and Rhabditis larvae. 21 samples from 79 samples were egg positive, the positive rate being 26.6%. Green vegetable, water spinach and three-coloured amaranth had a higher positive rate. 4 kinds of vegetables (onion, pakchoi, coriander and cucumber) among 7 kinds bought from the market in Shaowu County, were egg positive. In Jiangning County, 4 kinds (radish, onion, tomato and yam bean) from 9 kinds were positive (Al and/or S.). The egg positive rate of the shoe-sole soil samples in Shaowu County, Fujian Province (55.6% ) was higher than that in Jiangning County, Jiangsu Province (15.0%). 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.

Key words: Vegetable, shoe-sole soil, Ascaris egg contamination, filariform larva of hookworm, filariform larva of Strongyloides stercoralis
