Bartonella endocarditis: a culture-negative endocarditis clinical case report
Keywords:
Endocarditis, Bartonella, Culture-negative endocarditisAbstract
The diagnosis of infectious endocarditis is based on identification
of the causal agent and evidence of valvular alterations seen on
cardiac ultrasound. Cases of culture- negative endocarditis are a
clinical challenge, because they present frequently with a subacute
or chronic evolution and need other techniques for detection of the causative microorganism.
Bartonella sp. is an increasingly more frequent cause of
culture- negative endocarditis, and the diagnosis is based on an
epidemiological history and serological tests.
The authors present a case of a woman with a prosthetic valve
and several months history of fever and pancytopaenia, with negative cultures and serology positive for Bartonella spp.
A revision of the approach for diagnosis of the culturenegative endocarditis, specifically cases due to Bartonella sp.,
is reported.
