目的了解光照水电站库区鼠传疾病感染指标。方法现场随机分层抽样确定调查自然村寨(点)8个,采集鼠形动物、指示动物标本,用微量反向间接血凝法和间接血凝法检测鼠疫F1抗体。结果共捕获165只鼠形动物,分类为褐家鼠占39.39%(65只)、黄胸鼠占38.79%(64只),为优势种,小家鼠占20.00%(31只),为常见种。共收集鼠体寄生蚤483匹,分类鉴定为印鼠客蚤占97.5%(468匹),为优势种,缓慢细蚤占3.11%(15匹),为罕见种。共检测153份鼠形动物的肝脏组织匀浆液、147份鼠形动物的心脏滤纸血和33份指示动物(狗)的血清共333份标本,均未检出鼠疫F1抗原、抗体。结论由于抽样的范围和数量有限,光照水电站库区调查结果虽然没有检获鼠疫感染阳性指标,但该地区属亚热带高原气候,褐家鼠和黄胸鼠、印鼠客蚤分别为优势鼠、蚤种,具有形成黄胸鼠鼠疫疫源地的基本条件。因此加强该工程地区的鼠疫监测和库区蓄水前的大面积灭鼠工作十分有必要。 Objective To understand the rodent infection index of Guangzhao Hydropower Station. METHODS: Randomly stratified sampling was conducted to identify 8 natural villages (spots) in the survey. Murine animals were collected and the animal specimens were inspected. The F1 antibody against plague was detected by indirect indirect hemagglutination and indirect hemagglutination. Results A total of 165 rat species were captured, accounting for 39.39% (65) for Rattus norvegicus and 64 (38.79%) for Rattus flavipectus, accounting for 20.00% (31) for Mus musculus, which were common Species. A total of 483 parasitic fleas were collected, accounting for 97.5% (468) of them, the dominant flea species, and the slow flea accounting for 3.11% (15 horseshoe crabs). A total of 333 serum samples from 153 liver tissue homogenate of rat, 147 heart-shaped rat blood filter paper and 33 indicator animals (dog) were tested. No F1 antigen and antibody were detected. Conclusion Due to the limited scope and quantity of sampling, although there is no positive index of plague infection in the reservoir area of ​​Guangzhao Hydropower Station, the subtropical highland climate in this area, Rattus norvegicus and Rattus flavipectus are dominant species, , With the formation of raccoon plague origin of the basic conditions. Therefore, it is necessary to strengthen the plague surveillance in this project area and the large-scale anti-rodent control work in the reservoir area.
