*Ticks (n = 418) were sent to the Institut Hospitalo-Universitaire Méditerranée Infection in Marseille, France, during 2014–2021 for identification of tick and bacteria species by using mass spectrometry (ticks) and molecular and serologic methods (bacteria). CLB, Coxiella-like bacteria; MF, metropolitan France.
