摘要
目的了解甘肃省玉门市喜马拉雅旱獭鼠疫自然疫源地动物鼠疫流行规律,探讨当地鼠疫流行病学特点,为制订鼠疫防控政策提供科学依据。方法收集2014-2021年甘肃省玉门市喜马拉雅旱獭鼠疫自然疫源地鼠疫监测数据,分析主要宿主密度、染蚤率、蚤指数、小型啮齿类鼠种及细菌学、血清学检测结果,通过Excel 2007软件进行数据结果统计,分析该自然疫源地鼠疫流行情况。结果2014-2021年,玉门市喜马拉雅旱獭鼠疫自然疫源地内旱獭平均密度为0.06只/hm^(2);小型啮齿类鼠种调查共布鼠夹19300个,捕获鼠209只,捕获率为1.08%,三趾跳鼠(59.81%,125/209)和五趾跳鼠(31.10%,65/209)为该地区主要小型啮齿类鼠种。共梳检旱獭877只,检出染蚤旱獭184只,总染蚤率为20.98%,总蚤指数为1.00,斧形盖蚤(52.69%,461/875)和谢氏山蚤(47.20%,413/875)为优势蚤种;旱獭洞干染蚤率为7.72%(173/2241),蚤指数为0.20。疫源地内共分离鼠疫耶尔森菌(鼠疫菌)39株,其中以旱獭分离为主,共35株,媒介分离4株。共检测旱獭及牧羊犬血清913份,检出阳性血清34份,其中,牧羊犬血清阳性率为13.98%(33/236)。结论甘肃省玉门市喜马拉雅旱獭鼠疫自然疫源地鼠疫防控形势依然严峻,应继续加强鼠疫监测,全面落实各项综合防控措施,严防动物间鼠疫流行波及人群。
Objective To learn about the epidemic law of animal plague in natural plague focus of Himalayan Marmot in Yumen City of Gansu Province,to explore the epidemiological characteristics of plague in the area and to provide scientific basis for formulating prevention and control strategies of the plague.Methods The animal plague surveillance data of natural plague focus of Himalayan Marmot in Yumen City,Gansu Province from 2014 to 2021 were collected,main host density,rate of infected with fleas,flea index,small rodent species,bacteriology,serology were studied.Excel 2007 software was used to analyze the plague epidemic situation in the focus.Results From 2014 to 2021,the total average density was 0.06 per hm^(2) of the marmots.A total of 19300 traps were placed,and 209 rats were caught,with an average catch rate of 1.08%.Among them,Dipus sagitta(59.81%,125/209)and Mongolian Five-toed Jerboa(31.10%,65/209)were dominant small rodent species.Totally 877 marmots were checked,184 with flea.The rate of infected with fleas of marmots was 20.98%,with a flea index of 1.00,Callopsylla dolabris(52.69%,461/875)and Oropsylla silantiewi(47.20%,413/875)were dominant species in vector.The rate of infected with fleas of burrow was 7.72%(173/2241),with a flea index of 0.20.A total of 39 strains of Yersinia pestis were isolated from infected animals.Among them,35 strains from the marmots,and 4 strains from vectors.Totally 913 serum samples were checked from marmots and shepherd dog,the positive serum was 34.Among them,the positive rate of shepherd dog was 13.98%(33/236).Conclusions The plague epidemic situation in natural plague focus of Himalayan Marmot in Yumen City of Gansu Province is still serious.The monitoring of plague should be strengthened,and the comprehensive measures for prevention and control of the plague should be carried out to prevent a outbreak of the plague in human being.
