[Coxiella burnetii endocarditis on a mechanical valvular prosthesis. Apropos of 2 cases].

The authors report two cases of prosthetic valve endocarditis due to Coxiella burnetii. The histories were chronic and complex suggesting an auto-immune disease: prolonged recurrent fever despite antibiotic therapy with a biological inflammatory syndrome whilst blood cultures remained negative. The first patient presented with prosthetic valve dehiscence and acute glomerulonephritis.
