A total of 155 fleas collected in 2009 in Lebanon from 16 cats (104 Ctenocephalides felis specimens, 1 C. canis specimen) and 2 dogs (50 C. canis specimens) were tested for the presence of Rickettsia spp. and Bartonella spp. using molecular methods, including real-time quantitative polymerase chain reaction (PCR), regular PCR, and sequencing of amplified PCR products. Rickettsia felis, the agent of the emerging flea-borne spotted fever in humans, was identified in 17 (16%) C. felis cat fleas. Bartonella henselae, an agent of cat scratch disease, was identified in three (2.9%) C. felis. Our results emphasize the potential risk of these emerging flea-borne infections in Lebanon.
2009 年，在黎巴嫩从 16 只猫（104 只猫栉首蚤标本、1 只犬栉首蚤标本）和 2 只狗（50 只犬栉首蚤标本）中采集了总共 155 只跳蚤，使用分子方法，包括实时定量聚合酶链反应（PCR）、常规 PCR 和扩增 PCR 产物的测序，对这些跳蚤进行了立克次体属和巴尔通体属的检测。在 17（16%）只猫栉首蚤中鉴定出了引起人类新发跳蚤传播斑点热的病原体猫栉首蚤立克次体。在 3（2.9%）只猫栉首蚤中鉴定出了引起猫抓病的病原体亨氏巴尔通体。我们的研究结果强调了这些新发跳蚤传播感染在黎巴嫩的潜在风险。
