用动物模型及膜饲养方法对云南家、野两型鼠疫疫源地的七种蚤进行了传播鼠疫多项指标（感染率、菌栓形成率、媒介效能等八项）的全面研究，并以完全量化和数据来界定其媒介地位、媒介作用。结果表明：印鼠客蚤、特新蚤分别是家、野疫源地的主要媒介；人蚤是云南人间鼠疫的重要媒介。报道了印鼠客蚤、特新蚤能形成两次性菌栓；人蚤、特新蚤、棕形额蚤、不等单蚤的媒介效能和媒介指数；七种蚤对人的嗜血性及生存期限；从媒介角度揭示家鼠疫源地的稳定性和顽固性，推断疫源地从静止到复燃的原因；还修正了缓慢细蚤的媒介地位；在野鼠鼠疫疫源中否定了方叶栉眼蚤起主要媒介的作用，佐证了高山姬鼠在该疫源地主要宿主的地位 Seven species of plague foci of Yunnan wild type and two types of wild type plague were investigated by animal models and methods of membrane rearing in a comprehensive study of several indicators (infection rate, Complete quantification and data to define its media status, media role. The results showed that: the rat and flea fleas were new fleas, respectively, the main media of wild foci; flea fleas Yunnan is an important medium for human plague. It was reported that the physical and media indices of fleas, traps, fleas, flea beetles, flea beetles, and flea fleece-nos. Survival period; from the media point of view to reveal the stability and intractability of the house mouse foci to infer the origin of the foci from rest to rekindle; also fix the slow the flea’s media status; The role of Cichlids flea as a major medium has corroborated the status of Alpine Apodemus major host in the foci
