The blood-sucking arthropod Ctenocephalides felis has been confirmed as a vector for Bartonella henselae and is a suspected vector for Bartonella clarridgeiae, Bartonella quintana and Bartonella koehlerae in Bartonella transmission to mammals. To understand the absence of other Bartonella species in the cat flea, we have developed an artificial flea-feeding method with blood infected successively with five different Bartonella species. The results demonstrated the ability of these five Bartonella species to persist in C. felis suggesting an ability of fleas to be a potential vector for several Bartonella species. In addition, we demonstrated a regurgitation of Bartonella DNA in uninfected blood used to feed C. felis thus suggesting a potential horizontal transmission of Bartonella through C. felis saliva. On the contrary, no vertical transmission was detected in these artificial conditions.
已确认吸血节肢动物猫栉首蚤为巴尔通体属细菌（Bartonella henselae）的传播媒介，并被怀疑是巴尔通体属细菌（Bartonella clarridgeiae、Bartonella quintana 和 Bartonella koehlerae）向哺乳动物传播的媒介。为了了解猫栉首蚤中是否存在其他巴尔通体属细菌，我们使用先后感染了五种不同巴尔通体属细菌的血液，开发了一种人工跳蚤喂养方法。结果表明，这五种巴尔通体属细菌能够在猫栉首蚤中持续存在，这表明跳蚤有能力成为几种巴尔通体属细菌的潜在传播媒介。此外，我们还证明了在未感染的血液中存在巴尔通体属细菌的反刍现象，这表明巴尔通体属细菌可能通过猫栉首蚤的唾液进行水平传播。相反，在这些人工条件下，未检测到垂直传播。
