2004～2006年龙岩市鼠疫宿主动物监测结果分析

[目的]了解龙岩市鼠疫宿主动物及其寄生蚤类的种群构成和数量分布情况，为鼠疫防治工作提供科学依据。[方法]对2004-2006年龙岩市监测点鼠疫宿主动物监测资料进行分析。[结果]3年合计捕获鼠形动物3305只，隶属2目2种3属5种，其中啮齿目动物2899只，食虫目动物406只，鼠密度为4．32％，黄胸鼠密度为2．17％。3305只鼠形动物中，染蚤鼠1674只，捡获蚤5353匹（包括印鼠客蚤、缓慢细蚤、不等单蚤），染蚤率为50．65％，总蚤指数为1．62。黄胸鼠蚤指数为1．93，黄胸鼠印鼠客蚤指数为1．68。室内游离蚤指数为0．05。检测鼠疫宿主动物血清3289份，鼠疫F1抗体均为阴性；检测肝、脾1551份，鼠疫F1抗原全为阴性。[结论]黄胸鼠是龙岩市的主要鼠种，主要蚤种为印鼠客蚤，黄胸鼠密度及黄胸鼠印鼠客蚤指数均超出鼠疫控制标准。未发现鼠间鼠疫流行迹象。

Analysis on Monitoring Results of Plague Host Animal in Longyan City from 2004 to 2006

[Objective] To understand the structure and distribution of animal species for plague host animals and parasitic fleas in Longyan City,to provide scientific evidence for plague prevention and control.[Methods]Monitoring data of plague host animal in Longyan City from 2004 to 2006 were analyzed.[Results]3 305 animals of rat shape were captured in 3 years,they were divided into 2 orders,2 families,3 genera and 5 strains,including 2 899 rodents and 406 animals of insectiviora.The density of rat was 4.32%,The density of rattus flavipectus was 2.17%.Among 3 305 animals of rat shape,1 674 animals were found with fleas and 5 353 fleas were collected(including xenopsylla cheopis,leptopsylla segnis and monopsyllus anisus).The flea infection rate of rats was 50.65%,the total flea index was 1.62.The rattus flavipectus flea index was 1.93 and the xenopsylla cheopis index of rattus flavipectus was 1.68.The indoor dissociating flea index was 0.05.3 289 samples of the plague host animal serum were tested,the plague F1 antibody was negative,1 551 samples of liver and spleen were tested,the plague F1 antigen was not found.[Conclusion]The rattus flavipectus was the main species of rat in Longyan City and the main species of flea was xenopsylla cheopis.The density of rattus flavipectus and the xenopsylla cheopis index of rattus flavipectus all went beyond the standard of plague control.No sign of plague prevalence among rats was found.
