目的了解海南省鼠疫的主要宿主动物和媒介蚤类的密度和种群分布情况,为预防控制鼠疫提供科学依据。方法运用流行病学方法,在2002~2006年期间对海南省海口、澄迈、儋州等8个市县开展调查,采集鼠型动物的肝脾和血清、指示动物血清、人血清和媒介蚤标本,检测鼠疫杆菌和鼠疫F1抗体。结果在调查市县发现啮齿动物隶属2目2科4属9种,以褐家鼠为优势鼠种,黄胸鼠次之;食虫目动物1科1属1种;梳检鼠体检获鼠体蚤3科4属4种,以印鼠蚤为绝对优势蚤种;未发现自毙鼠;未分离出鼠疫杆菌及未检测出F1抗体阳性血清。结论海南省海口、澄迈、儋州等8市县鼠疫仍处于静息期,目前未发现鼠疫自然疫源地,但主要宿主和主要媒介却广泛存在。

Objective To understand the density and population distribution of major host animals and vector fleas in plague in Hainan Province and provide a scientific basis for the prevention and control of plague. Methods Epidemiological methods were used to survey eight cities and counties in Haikou, Chengmai and Zhuozhou of Hainan Province from 2002 to 2006. Liver, spleen and serum of murine animals were collected, serum of animal, human serum and flea Specimens were tested for Yersinia pestis and plague F1 antibodies. Results In the investigation of city and county, rodents belonging to 2 orders, 2 families, 4 genera and 9 species were found, Rattus norvegicus was the dominant species, followed by the Rattus flavipectus; The body fleas 3 families and 4 genera and 4 species, with the Indiana fleas as the absolute dominant flea species; never found dead; rats were not isolated and not detected F1 antibody positive serum. Conclusions The plague epidemics in Haikou, Chengmai, Zhuozhou and other 8 counties in Hainan Province are still at rest. There are no natural foci of plague yet, but the main hosts and major vectors are widespread.
