The authors report a case of tricuspid blood culture-negative endocarditis where serologic investigations showed high titers of antibodies against. Chlamydia pneumoniae, thus suggesting its possible role as the causal agent. The treatment consisted of polymicrobial therapy using ciprofloxacine and doxycycline with favorable response thus avoiding surgical intervention. In all cases of culture-negative endocarditis not responding to classic empiric antibiotics, Chlamydia infection should be suspected. Although rare cases of endocarditis due to Chlamydia pneumoniae have been reported in the literature, to our knowledge, this is the first case of isolated tricuspid valve endocarditis due to this agent to be reported.
