摘要
云南澜沧江边媳姑坝,1956年证实为恙虫病自然疫源地。1979年4月到1980年5月,笔者在该地进行了有关调查研究。共获恙螨幼虫6790只,计16个种类,地里纤恙螨为优势种。恙螨幼虫在鼠体出现的时间和数量,是随温湿度和雨量的不同而有所差别;地里纤恙螨等季节分布十分明显;同时显示出恙螨幼虫一定的嗜温性及嗜冷性的差别。恙螨幼虫的寄主有7种小型哺乳动物,平均染带率为42.31%,总指数为20.09;主要寄主为斯氏家鼠及黄胸鼠。从鼠体及地里纤恙螨分离到恙虫病立克次体13株,说明该地仍然且牢固地存在恙虫病自然疫源地。
The of natural foci tsutsugamushi disease in Xigu Flatland District besides Lancan river in Yunnan Province was confirmed in 1956.We studied it from April 1979 to May 1980, totally collected mite larvaes 6790, 16 species, and Leptotrombidium(L.)deliense was the preponderent species.The time and quantity of mite larvaes occured on rat changed with the difference of temperatore humidity and rainfull, the L.deliense seasonal distribution is very obvious, the mite larvaes have fixing addiction to warm and cold seven small animmals are its host and thhe average carriing rat was 42.3%, general index was 29.09, primary host was Rattus sladeni and R.flavipectus. 13 strains Tsutsugamoshi disease virus are isolated from Rats and L.deliense. The results explain the existence of the natural foci tsutsugamoshi disease
