Analysis of Special Surveillance on Rodents at Border Ports in Heilongjiang Province from 2019 to 2020

本研究旨在掌握黑龙江省12个边境口岸鼠形动物的种群构成,为黑龙江省边境口岸鼠类防制及鼠传疾病防控提供科学依据。采用夹夜法和鼠笼法,分别于2019年和2020年的5—10月进行监测,每月上下旬各监测1次,共捕获各类鼠形动物1200只,隶属于1目3科10属12种,优势种为黑线姬鼠,占52.16%,褐家鼠占17.16%。经检测,9种病原体呈阳性,包括汉坦病毒H型28例,汉坦病毒S型18例,斑点热群立克次体282例,伯氏疏螺旋体13例,巴尔通体109例,博卡病毒103例,钩端螺旋体12例,Q热立克次体4例,斑疹伤寒立克次体4例,嗜吞噬细胞无形体2例。鼠类病原体复合感染例数较多,共120例,占20.94%,且有三重感染、四重感染的情况。

This study is intended to grasp the population composition of rodents at 12 border ports in Heilongjiang Province,and provide scientific basis for rodent control and rodent-borne diseases prevention and control at border ports in Heilongjiang Province.The night trap method and the cage method were adopted,and the monitoring was carried out once a month from May to October 2019 and 2020.A total of 1200 rodents of various types were captured,belonging to 1 order,3 families,10 genera,12 species,among which Apodemus agrarius,as the dominant species,accounted for 52.16%,and Rattus norvegicus 17.16%.A total of 9 pathogens were detected as positive,including 28 cases of Hantavirus H type,18 cases of Hantavirus S type,282 cases of spotted fever group Rickettsia,13 cases of Borrelia burgdorferi,109 cases of Bartonella,103 cases of Bocavirus,12 cases of Leptospira,4 cases of Q fever rickettsiae,4 cases of typhus rickettsiae,and 2 cases of phagocytic anaplasma.There were a large number of murine pathogens with multiple infections,a total of 120 cases,accounting for 20.94%,and there were triple infections and quadruple infections.
