2006-2013年云南省保山市隆阳区鼠疫监测结果分析

Surveillance of Plague in Longyang District of Baoshan City, Yunnan Province,2006-2013

目的通过监测鼠疫的宿主动物及媒介昆虫,以及早发现鼠疫疫情,及时采取防控措。方法云南省保山市隆阳区2006-2013年采用笼夹法捕鼠,对捕获的活鼠进行分类鉴定,采其肝脾,对鼠及蚤标本分别培养鼠疫菌及进行鼠疫血清F1抗体检测,计算鼠密度,染蚤率,蚤指数等。结果家栖鼠和野栖鼠主要以黄胸鼠和臭鼰靑(食虫目)为主,室内外平均鼠密分别为0.494 7%,0.689 2%。家栖鼠平均染蚤率为29.53%,总蚤指数为0.348 2,鼠体寄生蚤以缓慢细蚤和印鼠客蚤占绝对优势。结论虽然历史疫区的宿主和媒介种类构成保持相对稳定,密度低,但仍应开展监测工作,及时发现异常信号,采取必要的措施,防止鼠疫复燃。

Objective By surveillance on host animal and vector insects to detect the plague in advance and formulate prevention and control measures. Methods With cage-clap method,the mouse in Longyang district of Baoshan city during 2006-2013 were captured and classified. The liver and spleen were collected and the samples of mouse and flea were cultured plague bacillus and tested of plague serum F1 antibody. The density,flea infection rate and flea index were calculated. Results Rattus flavipectus was the main rattus and Choujuqing（ insectivora） was the main wild-habitant mouse. The average outdoor and indoor density of mouse was respectively 0. 494 7% and 0. 689 2%. The average density of rattus was 29. 53%,the total flea index was 0. 348 2. Leptopsylla musculi and cheopis Xenopsylla dominated major parasitic fleas. Conclusion Although the constitution of hosts and vector are relatively steady in history epidemic area and the density stays at a low level,surveillance work should be carried out to timely detect the abnormal signals and take necessary actions to prevent the recurrence of plague.
