title: [Q fever infectious endocarditis. 3 cases].
abstract: An acute infectious disease with predominant pulmonary symptoms, Q fever, may become chronic as hepatitis or, more frequently, endocarditis. We report 3 cases of Q fever endocarditis. In 2 of these patients endocarditis developed on cardiac valve prosthesis. The 3 patients have been under doxycycline for more than a year, and their condition is satisfactory. A review of the literature provides additional data on the epidemiological, aetiological, clinical, biological and therapeutic aspects of this rare type of endocarditis. It is recommended to look for chronic Q fever in all cases of endocarditis with negative blood cultures.
