为确定云南家野两型鼠疫疫源地主要蚤类的媒介作用，１９８９～１９９６年我们对云南７种蚤类进行了单只传播和集群传播鼠疫的研究。结果表明，集群传疫率高的蚤，单只传疫率也高，媒介作用也越大。１材料和方法１．１实验蚤种及来源 印鼠客蚤、缓慢细蚤、不等单蚤、特新蚤指名
In order to determine the vector function of major fleas in the two wild type plague foci in YunNan province, from 1989 to 1996, we conducted a survey of seven species of fleas in Yunnan province. The results showed that flea with high cluster transmission rate had high single transmission rate and also had greater vector effect. 1 Materials and methods 1.1 Fleas species and origin of the experimental rat flea flea, slow flea, ranging from single flea, New flea named
