In this study, we analyze the presence of emerging zoonotic bacteria in ticks collected from passerine birds and mammals present in the Camargue, in the south of France, which is a major rallying point for birds migrating from Eurasia and Africa. The presence of Coxiella burnetii, Rickettsia, Borrelia, and Bartonella was examined by real-time PCR on DNA samples extracted from 118 ticks. Rickettsia massiliae was detected in ticks from Passer domesticus, Ri aeschlimannii in ticks from Acrocephalus scirpaceus and Luscinia megarhynchos, and Borrelia valaisiana in one tick from Turdus merula. In addition, Ri. massiliae, Ri. slovaca, Candidatus Ri. barbariae, and C burnedi were detected in ticks from dogs, horses, cats, and humans. No Bartonella DNA was detected in these samples. The migratory birds may play a role in the transmission of infectious diseases and contribute to the geographic distribution of Ri. aeschlimannii, Bo. valaisiana, and C. burnetii. The role of birds in spreading Rh. sanguineus ticks infected with Ri. massiliae needs to be clarified by complementary studies. This is the first detection of Candidatus Ri. barbariae in Rh. sanguineus from the south of France. 080 ; 052 UR198
