GARRE, Luis et al. Infective endocarditis due to Bartonella quintana. Medicina (B. Aires) [online]. 2008, vol.68, n.2, pp.144-146. ISSN 0025-7680.

We present the clinical case of a man of 68 years who was admitted for dizziness and sensation of loss of conscience. The clinical examination revealed a body temperature of 37.5 °C and a murmur of mitral regurgitation. The echocardiogram showed a severe mitral regurgitation and left cavitie's dilatation; transesophageal echocardiogram showed a vegetation in the anterior leaflet of the mitral valve. In blood cultures grew a Gram-negative bacteria identified as Bartonella spp. A PCR demonstrated that it was a Bartonella quintana. The patient was treated with gentamicin, doxiciclin and ceftriaxone with satisfactory evolution. The remaining mitral insufficiency awaits surgical treatment.
