Bactérie intracellulaire stricte, non colorable au Gram, non cultivable en routine. Pneumonie communautaire atypique d'évolution lente, souvent précédée d'une pharyngite ou d'une laryngite ; diagnostic par PCR sur prélèvement respiratoire, la sérologie étant d'interprétation difficile. Insensible aux bêta-lactamines : macrolide ou doxycycline (IDSA/ATS 2019). À distinguer de C. trachomatis (infections sexuellement transmissibles, trachome) et de C. psittaci (psittacose, exposition aviaire).

No renal or hepatic, paediatric or pregnancy adjustment is provided systematically. These regimens have not been reviewed by any infectious-disease specialist to date.
