摘要
目的了解伍氏病蚤雷州亚种和穗缘端蚤中缅亚种叮吸人血情况,评价它们的鼠疫流行病学意义。方法将试验蚤固定于受试者的前臂和小腿,让蚤自由叮咬吸血。结果伍氏病蚤的吸血率为63.48%,其吸血率与蚤的性别,以及人的年龄、血型和叮咬的部位差异均无统计学意义;穗缘端蚤的吸血率为11.71%,它对人的血型和叮咬部位有选择性。结论2种蚤都能叮吸人血。伍氏病蚤较穗缘端蚤的吸血能力强,具有非常重要的鼠疫流行病学意义。
Objective To study the behavior of Nosopsyllus wualis laizhouensis and Acropsylla episema girsharni biting and sucking human blood, to provide evidence for evaluting the significance of N. w. laizhouensis and A. e. girshami in plague disease epidemiology. Methods Fix fleas fixed on volunteer＇s antebrachium and crus, to bite and suck freely. Results The sucking rate of N. w. laizhouensis is 63.48 % , there were no significan differences among the sex of flea, man＇s age, man＇s blood type and position of biting. The sucking rate of A. e. girshami is 11.71%, the selectivity on man＇s blood type and position of biting was found in our study. Conclusion They all can bite and suck man＇s blood. The biting and sucking blood ability for N.w. laizhouensis is stronger than for A.e. girsharni, and both of them are great significance in plague epidemiology.
