摘要
作者对云南省江川县和湖南省衡山县各10户农家庭院、畜圈舍、厨房、门等处土中土源性线虫卵的分布进行了调查。结果:检获了蛔虫、鞭虫、缩小膜壳绦虫和肝毛细线虫的虫卵。这些虫卵在畜禽圈舍、厕所和厨房的土壤中分布较多。厨房土壤中检出的虫卵大多是随被污染的土壤和蔬菜从外界带入,因此厨房被认为是人体感染土源性线虫的场所之一。由于中国以粪便作为肥料,因此粪便的无害化处理是预防寄生虫感染的重要措施。
Distribution of the ova of soil-transmitted nematoda in the soil of the courtyard, Shed of the domestic animals nnd fowls, lavatory. kitchen and door was investigated in the peasant family. The ova of Ascaris, Trichuris, Hymenolepis diminuta and Capillaria hepatica were found out. The ova were more in the soil of shed of the domestic amimals and fowls, lavatory and kitchen. Because the night soil was used for fertilizer, the innocent disposal of night soil was an important measure in prevention of parasite infection.
