目的调查广东省鼠疫原疫区鼠形动物及其病原学、血清学检测,为制定鼠疫的预防控制策略提供科学依据。方法采用笼(夹)法捕鼠,进行分类鉴定,间接血球凝集反应(IHA)检测鼠疫抗体。结果2008年在广东省12个县(市、区)共获鼠形动物1 699只,居民区和野外区的平均捕获率分别为7.93%和3.76%。其中在居民区的捕鼠数中黄胸鼠占36.43%、臭鼩鼱占33.44%和褐家鼠占30.13%,在野外区的捕鼠数中黄毛鼠占比例为47.29%,板齿鼠占37.74%。病原学方法检测6 944份,IHA检测5 933份鼠疫血清学结果均为阴性。结论广东省鼠疫宿主构成稳定且密度低,但应坚持监测工作,防止鼠疫的发生。
Objective To investigate the rat plague origin and its etiological and serological detection in the plague origin area of Guangdong Province and provide a scientific basis for formulating the prevention and control strategy of plague. Methods The rats were caught by cage method and identified by classification. The IHA antibody was detected by indirect immunodetection. Results A total of 1 699 rat-shaped animals were obtained in 12 counties (cities and districts) in Guangdong Province in 2008, with an average capture rate of 7.93% and 3.76% in residential areas and in open areas respectively. Among them, Rattus flavipectus accounted for 36.43%, Rattus ostreatus accounted for 30.4% and Rattus norvegicus accounted for 30.13%. In the wild area, the ratio of Rattus flagella was 47.29% Accounting for 37.74%. 6 944 were tested by etiological methods and 5 933 by IHA were negative by serological tests. Conclusion The host population of plague in Guangdong province is stable and low in density, but monitoring work should be persisted to prevent the occurrence of plague.
