摘要
1987年7月中旬,云南省盈江县县城居民区,连续发生自毙鼠。前往调查时找到自毙黄胸鼠(Rattus flavipectus)3只、小家鼠(Mus musculus)1只,经鼠疫反相间接血凝试验,结果均为阳性,并分离到家鼠生态型鼠疫菌2株。 调查结果该地具备鼠、蚤生存繁殖的优生境,黄胸鼠为优势鼠种。1987年7月中旬以来发生小范围的鼠间鼠疫流行,主要染疫动物是黄胸鼠。导致鼠疫流行的主要原因是有家鼠鼠疫疫源地存在和局部鼠密度升高。
Four self-dead rats (3 Rattus flavipectus and 1 Mus musculus) were found in the residential area of Yingjiang county town in July, 1987 and, positive results were obtained when the rats were examined by reverse passive hemagglu-tination test and 2 strains of Y .pestis were isolated. Investigations showed that conditions there were very suitable for the breeding of rats and fleas and R .flavipectus was the dominant rat. Plague epizootic had been prevalent within a narrow ranage since July, 1987 and R.flavipectus were the main animals infected, the main cause of the prevalence were the existence of natural foci of plague and the rise of the rats density.
