目的分析百色市2010-2014年5年间鼠疫宿主动物及媒介监测结果,掌握百色市鼠疫疫情现状,为制定百色市鼠疫防控策略提出科学依据。方法通过收集2010-2014年百色市录入鼠疫防治管理信息系统的鼠密度、鼠体染蚤率、蚤指数、抗原、抗体、脏器培养结果等指标。采用SPSS16.0软件进行统计分析。结果 2010-2014年共捕获鼠类动物20 569只,总密度6.19%(20 569/332 492),黄胸鼠构成比为45.16%(9 288/20 569),褐家鼠构成比为43.30%(8 906/20 569);2010-2014年全市共检鼠类动物15 300只,累计带蚤鼠体3 132只,染蚤率20.47%(3 132/15 300),总鼠体染蚤率呈逐年下降趋势(χ~2=23.38,P<0.05),黄胸鼠染蚤率呈逐年下降趋势(χ~2=51.79,P<0.05);共获蚤数7 811匹,总蚤指数为0.51(7 811/15 300),印鼠客蚤构成比为84.59%(6 607/7 811)。培养鼠脏器12 775份,结果均为阴性;检测鼠血清19 422份,结果均为阴性。结论黄胸鼠、褐家鼠为百色市优势宿主种群,印鼠客蚤为优势媒介蚤,百色市鼠疫正处于静息状态。
Objective To analyze the monitoring results of plague host animals and vectors in Baise City during the five years from 2010 to 2014 and to grasp the current situation of the plague in Baise Municipality for the purpose of formulating the scientific basis for the prevention and control of plague in Baise City. Methods By collecting the rat density, flea flea rate, flea index, antigens, antibodies, organ culture results and other indicators of the plague prevention and management information system entered into Baise City in 2010-2014. Using SPSS16.0 software for statistical analysis. Results A total of 20 569 rodent animals were collected from 2010 to 2014, with a total density of 6.19% (20 569/332 492), a ratio of 45.16% (9 288/20 569), and a Rattus norvegicus ratio of 43.30% (8 906/20 569). From 2010 to 2014, a total of 15 300 rodent animals were examined in the city. There were 3 132 flea rats accumulated in the city, with a flea infection rate of 20.47% (3 132/15 300) (Χ ~ 2 = 23.38, P <0.05). The rate of flea infection in Rattus flavipectus decreased year by year (χ ~ 2 = 51.79, P <0.05). The total number of fleas was 7 811 and the total flea index was 0.51 (7 811/15 300), while the composition ratio was 84.59% (6 607/7 811). 12 775 mice were cultured, the results were negative; 19 422 serum samples were tested, the results were negative. Conclusion Rattus flavipectus and Rattus norvegicus are the predominant host populations in Baise City. The dominant species is flea fleece in Baise, and the plague in Baise City is at rest.
