摘要
为了解掌握河北省鼠疫自然疫源地室内游离蚤的种类、蚤指数的年度变化和季节消长 ,研究其在传播鼠疫过程中的流行病学意义 ,以指导鼠疫防治工作 ,对 1988～ 2 0 0 2年间河北省的有关资料进行了统计和研究。结果共发现 5种蚤 ,人蚤占 99% ,室内游离蚤出现在 5～ 8月份。蚤指数的高低与气温有密切关系 ,气温高的月份 ,蚤指数则高 ,蚤指数 7月份为最高 ,平均指数为 0 .10 4。
To understand the species,yearly changes and seasonal fluctuation of the indices at rooms in the plague natural foci of Hebei Province, and to study their epidemiological significance in transporting plague for conducting the works of plague prevention and control, we statisticed and studied the relative materials from 1988～2002. As a result, 5 species of fleas were found. Pulex irritans acconunted for 99%. The free fleas at rooms could be captured from 5～8 months. The fluctuation of the indices closely related to the temperature. The highest indices was in July,average 0.104.
