Migratory birds can transport infected ticks across continents. We evaluated pathogens in ticks collected from migratory birds in Italy. We found DNA from Rickettsia aeschlimannii, R. africae, and R. raoultii bacteria, all of which can cause disease in humans. Bird migrations might facilitate the spread of these pathogens into new areas.
候鸟可以携带感染的蜱虫跨越各大洲。我们评估了在意大利迁徙鸟类中采集的蜱虫携带的病原体。我们发现了立克次体属细菌的 DNA,包括埃及立克次体、非洲立克次体和拉乌尔立克次体,这些细菌都可能导致人类患病。鸟类迁徙可能会促进这些病原体传播到新的地区。
