目的分析2015年新疆温泉县鼠疫监测点阿拉套山及别珍套山鼠疫疫源地的调查结果,了解并掌握该疫源地的范围以及旱獭动物间鼠疫流行情况,为防治鼠疫流行提供科学依据。方法系统收集2015年温泉县在鼠疫疫源地监测中有关旱獭动物间鼠疫流行的情况并进行流行病学、生态学、血清学和病原学分析。结果 2015年5月与7月路线法调查灰旱獭密度分别为0.69 ind/hm~2和0.50 ind/hm~2,定点法密度分别为3.0 ind/hm~2和2.3 ind/hm~2,7月比5月降低;采集各种动物活体脏器181份,其中捕获旱獭47份,长尾黄鼠134份,取动物肝、脾按“四步法”分组检验,未检出鼠疫杆菌;检验自毙旱獭材料30份,分离出12株鼠疫菌,其中灰旱獭脏器10份分离出鼠疫菌,从病死灰旱獭体外蚤谢氏山蚤(Oropsylla silantiewi)分离出1株鼠疫菌、草原硬蜱(Ixodes crenulatus)分离出鼠疫杆菌1株。结论 2015年在温泉县阿拉套山及别珍套山旱獭鼠疫自然疫源地范围内检出了鼠疫菌,说明该疫源地旱獭动物间鼠疫流行猛烈。
Objective To analyze the survey results of the plague foci of Alashan Mountain and Biezhimen Mountain in Plague Spot of Wenquan County in Xinjiang in 2015 to understand and grasp the scope of the foci and the prevalence of plague in the marmot and provide a scientific basis for the prevention and control of plague epidemics . Methods The epidemiological, ecological, serological and etiological analyzes of plague prevalence in the monitoring of plague foci in 2015 in Wenquan County were collected. Results The density of O. marmota was 0.69 ind / hm ~ 2 and 0.50 ind / hm ~ 2, respectively. The density of spot method was 3.0 ind / hm ~ 2 and 2.3 ind / hm ~ 2,7 Month than in May to reduce; collected a variety of animal living organs 181, which captured 47 parts of marmot, long-tailed Salmonella 134, take the animal liver and spleen by the “four-step method” group test did not detect Yersinia pestis ; Test self-natatorium material 30, 12 strains of Yersinia pestis were isolated, of which 10 were gray plague organ Yersinia pestis isolates from the dead milt otter fleas Xie fleas (Oropsylla silantiewi) isolated from a plague bacteria, grassland Ixodes crenulatus isolate one of the Yersinia pestis. Conclusions In 2015, Yersinia pestis was detected in the natural foci of Atratales from Wenquan County and plague of Bezhenju, indicating that the epidemic of plague among the marmot animals in the foci was fierce.
