内蒙古高原长爪沙鼠鼠疫疫源地媒介现状分析

Analysis of current situation of plague vectors in Meriones unguiculatus plague foci on Inner Mongolian Plateau

目的掌握内蒙古高原长爪沙鼠鼠疫疫源地鼠疫媒介现状,为科学控制长爪沙鼠鼠疫提供依据。方法收集内蒙古高原长爪沙鼠鼠疫疫源地2000-2011年鼠疫媒介资料并进行统计和分析。结果 2000-2011年共检蚤96411匹(24040组),阳性蚤1657匹(533组),阳性率为1.72%(组阳性率为2.22%)。结论内蒙古高原长爪沙鼠鼠疫疫源地动物鼠疫流行非常活跃,是中国鼠疫动物病流行强度最大的疫区之一,蚤类在内蒙古人间鼠疫的感染中占有重要地位,应对疫源地进行长期、系统地监测,才能有效地控制人间鼠疫的发生和流行。

Objective To investigate the current situation of plague vectors in the Meriones unguiculatus plague foci on the Inner Mongolian Plateau and to provide a basis for scientific control of M. unguiculatus plague. Methods The 2000-2011 data on plague vectors in the M. unguiculatus plague foci on the Inner Mongolian Plateau were collected and then subjected to statistical analysis. Results In 2000-2011, 96 411 fleas （24 040 groups） were detected, including 1657 positive fleas （533 positive groups）, with a positive rate of 1.72% （group positive rate, 2.22%）. Conclusion Animal plague is prevalent in the M. unguiculatus plague foci on the Inner Mongolian Plateau, which is one of the animal plague affected areas with the highest epidemic strength in China. Flea plays an important role in human plague epidemic in Inner Mongolia. Long term systemic surveillance should be conducted in the plague foci to effectively control the occurrence and prevalence of human plague.
