【摘要】 1982～1986年在北京地区8个监测点先后检测1905只鼠。结果仅于1985,1986两年从通县、朝阳、某机场、顺义4个点的鼠类中检出6份黑线姬鼠鼠肺肾综合征出血热（HFRS）抗原、带毒率为0.9％～1.9％;检出抗体25份、阳性率为0.6％～11.2％;并以2份抗原阳性鼠肺接种Vero-E₆细胞首次分离出2株HFRS病毒。确定了北京地区HFRS的主要传染源为本地黑线姬鼠,并非由外地传入。从而证实北京地区HFRS自然疫源地的存在。更多还原

【Abstract】 Since 1982 to 1986, 1905 rats from 8 surveillant fegions in Beijing had been examined. 6 HFRS antigen were identified from the lung samples of apodemus agrarius pallss in 4 surveillant regions in 1985 and 1986,the rates of HFRS infection were 0.9%～1.9%;25 samples with antibody of HFRS virus were also detected, the seropositive rates were 0.6%～11.2%. Two HFRS antigen positive rat lung were incubated in Vero-E₀ cell medium and two strains of HFRS virus were isolated for the first time in Beijing,This study showed that the main infection source of HFRS is apodemus agrarius which is existing in Beijing natively.更多还原
