Recent large scale studies questioning the presence of intracellular bacteria of the Chlamydiales order in ticks and fleas revealed that arthropods, similarly to mammals, reptiles, birds or fishes, can be colonized by Chlamydia-related bacteria with a predominant representation of the Rhabdochlamydiaceae and Parachlamydiaceae families. We thus investigated the permissivity of two insect cell lines towards Waddlia chondrophila, Estrella lausannensis and Parachlamydia acanthamoebae, three bacteria representative of three distinct families within the Chlamydiales order, all documented in ticks and/or in other arthropods. We demonstrated that W. chondrophila and E. lausannensis are able to very efficiently multiply in these insect cell lines. E. lausannensis however induced a rapid cytopathic effect, which somehow restricted its replication. P. acanthamoebae was not able to grow in these cell lines even if inclusions containing a few replicating bacteria could occasionally be observed.
