目的研究近十年来广西鼠疫监测结果,为制定鼠疫防治对策提供依据。方法采用笼捕法,对捕获的鼠和蚤进行鉴定,并计算鼠密度、染蚤率和蚤指数;用鼠疫IHA法检测鼠疫F1抗体。对部分活鼠、蚤及疑似患者的标本进行病原体分离培养。结果 10年来共捕鼠154318只,检蚤33877匹,培养76814只鼠脏器和20份人体标本,分离出31株鼠疫杆菌,对142681份鼠血清进行间接血凝试验,阳性3份,对7460份指示动物血清进行IHA试验,阳性35份。鼠疫累计发生在2个县的4个乡(镇)34个自然屯。结论广西鼠疫由暴发→扩散→初步遏制,控制效果显著,但形势依然严峻。
Objective To study the surveillance results of plague in Guangxi during the past ten years and provide evidence for the prevention and control of plague. Methods The captured mice and fleas were identified by cage catching method, and the rat density, flea infection rate and flea index were calculated. The F1 antibody against plague was detected by the plague IHA method. On the part of live rats, fleas and suspected patients specimens for pathogen isolation and culture. Results Fifty-three hundred and seventy-eight mice were caught and 33877 fleas were seized during the past 10 years. Totally 76814 rat organs and 20 human specimens were cultured. 31 strains of Yersinia pestis were isolated and 142681 mouse serums were subjected to indirect hemagglutination test. The positive results were 7460 Serum samples were instructed for IHA test, 35 positive. The plague occurred in 34 natural villages in 4 townships (towns) in 2 counties. Conclusion The plague in Guangxi Province was initially controlled by outbreaks and dispersions. The control effect was remarkable, but the situation was still grim.
