摘要
流行性乙型脑炎(简称乙脑)是一种危害较大的自然疫源性疾病。在本病流行病学研究方面,国内外做了大量工作。明确了三带喙库蚊是主要传播媒介,猪是主要扩散宿主,并对长期宿主和流行预测进行了多方面的探索。为进一步了解乙脑病毒如何在自然界长期保存,我们于1986和1988年的7～8月在本省捕捉蝙蝠进行病毒分离及血清抗体调查,结果如下。
In July-August 1986 and 1988,three strains of viruses were isolated from 453 samples of brain tissues of bats ( Rousettus leschenaulti ) collected from Jinghong county, Yunnan Province, China. These viruses have been identified by hemagglutination inhibition ( HI ), complement fixation, immuno-fluorescent and neutralization tests. They have been proved to be Japanese encephalitis ( JE ) virus. Sera from Rousettus leschenaulii Jinghong were tested for antibodies against JE virus by HI test with a positive rate of 51.55% ( 150/291 ). These results demonstrated that natural infection with JE virus exists among bats in Yunnan Province.
