目的分析广州市鼠疫宿主动物及其媒介的种群构成及数量分布情况。方法于2006—2010年每年的3—10月在广州市的12个区按市区、郊区、郊县区域划分,每年选取不同的4个区县作为监测点,每监测点根据不同生态环境选取多个捕鼠点,采用夜笼法进行捕鼠。对捕获鼠类及捡获蚤类进行鉴定,计算鼠密度;计算鼠带(染)蚤率和蚤指数;用鼠疫IHA法检测鼠疫F1抗体。结果 5年共收有效笼36 549笼次,捕获鼠形动物4 082只,总鼠密度(捕获率)为11.17%,鼠密度(捕获率)为10.40%(其中黄胸鼠鼠密度为1.40%),分属2目2科4属9种。其中啮齿目动物3 800只,食虫目动物282只。啮齿目动物主要鼠种是褐家鼠73.24%(2 783只);在493只鼠形动物中发现染蚤鼠109只,平均鼠染蚤率为22.11%。染蚤鼠中检获蚤240匹。发现蚤类4种,主要蚤种为印鼠客蚤占97.92%;总蚤指数为0.47;检测鼠血清3 719份,未查出鼠疫F1抗体。结论广州市未发现鼠间鼠疫流行迹象。褐家鼠仍是广州市主要鼠种,主要蚤种是印鼠客蚤。 Objective To analyze the population composition and quantity distribution of plague host animals and their vectors in Guangzhou. METHODS: From March to October of each year from 2006-2010, 12 districts in Guangzhou were divided into urban, suburban and suburban counties. Four different counties and districts were selected as monitoring points each year. Each monitoring point was selected according to different ecological environment Multiple capture points, using night cage method to catch rats. The captured rodents and fleas were identified and the density of the rodents was calculated. The flea rate and flea index of the rodents were calculated, and the F1 antibody against the plague was detected by the plague IHA method. Results A total of 36 549 cage was collected in 5 years, and 4 082 mice were captured. The total rat density (capture rate) was 11.17% and the rat density (capture rate) was 10.40% (the density of the rat was 1.40% ), Belonging to 2 orders, 2 families, 4 genera and 9 species. Including 3 800 rodents and 282 insectivorous animals. The main rodents were Rattus norvegicus (73.24%) (2 783). In 493 rats, 109 fleas were found, the average rate of flea infection was 22.11%. Flea flea seized 240 horses fleas. 4 species of fleas were found, and the main flea species were 97.92% of Indian and Indian fleas; the total flea index was 0.47; 3 719 copies of serum were detected, but no F1 antibody was detected. Conclusion No plague epidemic in Guangzhou was found. Rattus norvegicus is still the main species in Guangzhou City, the main flea species is a rat off flea.
