本文从鄱阳湖区洲滩野粪污染指数、实验流行病学研究及耕牛放牧、尾蚴分析和钉螺感染的季节性变化等方面阐明了鄱阳湖区日本血吸虫的主要动物宿主为耕牛,病牛(尤其是3岁以下耕牛)为当地血吸虫病的主要传染源;分析了鄱阳湖区血吸虫传播特征,每年春季(4～6月),为血吸虫在终宿主(人和牛)和中间宿主相互传播的“交汇点”;涨水季节(7～8月)为血吸虫非易感季节,秋季(9～10月)为人畜感染的高峰,冬季(11月～翌年3月),为洲滩枯水期,血吸虫传播休止。终宿主和中间宿主的易感区域均为村旁的洲滩。
This article elucidates the main animal hosts of Schistosoma japonicum in the Poyang Lake area are cattle and sick cattle (especially in the aspects of stool pollution index, experimental epidemiology, cattle grazing, cercariae analysis and seasonal changes of snail infection in Poyang Lake area) Is the main source of infection of local schistosomiasis. It analyzes the characteristics of schistosomiasis transmission in Poyang Lake. It is the spring of each year (April to June) that the schistosomiasis is in the intersection of the terminal host (human and cow) and the intermediate host (September to August) is the non-susceptible season of schistosomiasis, the peak of human and animal infections in autumn (September to October), and the winter (November to March) . Susceptible areas of both the final host and the intermediate host are Chau Beach near the village.
