目的了解广东省27个口岸鼠形动物及其体表寄生虫种类,鼠疫耶尔森菌(鼠疫菌)和汉坦病毒感染状况,为口岸鼠传疾病防控提供科学依据。方法 2014年5月至2015年4月,采用鼠笼法捕获鼠形动物,实时荧光PCR法检测鼠肺,收集口岸人员健康状况。结果共捕获鼠形动物885只,平均密度为0.58%,优势种为臭鼩鼱(47.68%)和褐家鼠(33.67%);检出印鼠客蚤,染蚤率为0.79%,蚤指数为0.03。共检测鼠肺839份,10个口岸检出汉城型汉坦病毒,病毒携带率为2.74%,其中黄胸鼠携带病毒率最高(7.45%)。不同类型口岸鼠形动物汉坦病毒携带率差异无统计学意义(χ~2=3.287,P=0.349,ν=3)。未检出鼠疫菌。结论广东口岸的鼠形动物平均密度低于控制标准,未发现鼠间鼠疫流行线索,但存在黄胸鼠和印鼠客蚤,个别口岸汉坦病毒携带率较高,需采取措施预防控制鼠传疾病。
Objective To understand the species of mouse-borne animals and their surface parasites, the Yersinia pestis (Yersinia pestis) and Hantavirus infection in 27 ports of Guangdong Province and provide a scientific basis for the prevention and control of rodent-borne diseases. Methods From May 2014 to April 2015, mouse-shaped animals were captured by squirrel-cage method. Rat lungs were collected by real-time fluorescence PCR and the health status of port staff was collected. Results A total of 885 mouse-shaped animals were captured, with an average density of 0.58%. The dominant species were stinkbug (47.68%) and brown house mouse (33.67%). Is 0.03. A total of 839 rat lungs were detected, and hantavirus of Seoul was detected at 10 ports. The carrying rate of the virus was 2.74%, of which the virus carrying rate was the highest (7.45%). There was no significant difference in the carrying rate of hantavirus between different types of port animals (χ ~ 2 = 3.287, P = 0.349, ν = 3). Yersinia pestis was not detected. Conclusions The average density of mouse-shaped animals in Guangdong port is lower than the control standard. No epidemic clues were found for the rat plague, but the presence of Rattus flavipectus and Rattus flammeus and the carrying rate of Hantavirus in some ports were high. Measures should be taken to prevent and control rodents disease.
