合肥机场口岸鼠形动物及染螨的本底调查报告

A Baseline Survey on Rat-shape Animals and Mite Infection at Hefei Airport

〔目的〕了解合肥机场口岸地区鼠形动物、螨类本底情况,为制定有效的卫生控制措施及监测医学媒介生物提供依据。〔方法〕将合肥机场分为7类生态环境,设7个调查点,每月分上、中、下旬定点用鼠夹法和鼠笼法定点捕鼠,将1—4月捕获的鼠,取肺标本送安徽省疾病控制中心做肾综合征出血热病毒抗原检测。〔结果〕全年共布有效鼠夹和笼12723个,共捕获鼠形动物173只,年平均鼠密度为1.36%,隶属于2目2科4属5种,分别为黑线姬鼠、黄胸鼠、褐家鼠、小家鼠和灰麝鼩,其中褐家鼠为优势鼠种,占捕鼠总数的39.31%。采集到螨类19只,隶属于1目2科4属4种,分别为耶厉螨、格血厉螨、厩真厉螨、柏禽刺螨。肾综合征出血热抗原检测阳性3例,阳性率3.95%。〔结论〕应进一步加强鼠形动物防制和鼠类肾综合征出血热监测,严防肾综合征出血热的发生和流行。

Objective To understand the baseline of rats and mite infection at Hefei airport, and to provide a scientific evidence for surveillance of the medical-vector and the hygienic control. Method Hefei airport was be divided into 7 districts, regular examinations were conducted in three times a month, borh snap trap and cage trap was used at every spot. The lung samples of rat-shape animals were provided to Anhui Province Center for Disease Prevention and Control for hemorrhagic fever antigen detection from January to April . Result A total of 12 723 snaps and cages were laid out in a year and 173 rat-shape animals were caught, which belong to 2 orders, 2 families, 4 genera and 5 species. R. norvegicus Berkenheut was the dominate rat specie, accounting for 39.31%, average rat density was 1.36%. 19 mites were detected on 76 rat-shape animals, which belong to 1 orders, 2 families, 4 genera and 4 species. The Hemorrhagic fever antigen in 3 samples was positive. Conclusion It is important to strengthen further prevention and control of the rat-shape animals and surevillance of the Hemorrhagic fever epidemic.
