摘要: 1980~1982年,在水网型血吸虫病流行区的4个生产队用现场调查结合模拟实验的方法对虫卵落入有钉螺水体的机率作计量研究。结果发现当地一天血吸虫卵下有螺水体的推算总数,在夏季为12671.6个,在其它季节为9711.1个,分别占当地一天人、畜排血吸虫卵总数的0.90%和0.69%。定量地对比各种虫卵下水方式,发现全年各季均以下河洗刷马桶最为重要,耕牛粪便下水和河边田地施肥也较重要;在夏季,河边粪缸溢出较为重要,仅次于下河洗刷马桶。

Abstract: A quantitative study on the probability of the dispersion of schistosome eggs into Oncomelania-infested water bodies was carried out during 1980-1982 in a plain region of schistosomiasis endemic area by field survey and simulated experiments. The results showed that the daily estimated number of eggs contaminating the snail-infested water bodies was approximately 12 671.58 in summer and 9 711.08 in other seasons, accounting for approximately 0.996 and 0.6996 of the total daily fecal egg output respectively in the 4 villiages investigated.Quantitative comparison of different ways of egg contamination showed that the washing of commodes is of greatest importance. Direct defecation of tattle into water bodies and fertilization of the fields nearby the streams are of secondary importance while the cleaning of nightsoil buckets and dippers and promiscuous feces are of minor significance. However, in summer, the overflow of the night soil jars nearby the water body plays an important role just next to the washing of commodes.
