SICILIANO, Rinaldo Focaccia et al. Endocarditis due to Coxiella burnetii (Q fever): a rare or underdiagnosed disease? Case report. Rev. Soc. Bras. Med. Trop. [online]. 2008, vol.41, n.4, pp.409-412. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86822008000400017.
Q fever is a zoonosis of worldwide distribution that is caused by Coxiella burnetii. However, reports of this disease in Brazil are rare. Seroepidemiological studies have shown relatively high frequencies of antibodies against Coxiella burnetii in populations with occupational exposure. In humans, it can be manifested clinically as acute or chronic disease. Endocarditis is the most frequent chronic form of Q fever and the form with the greatest morbidity and mortality. We report a severe case of endocarditis due to Coxiella burnetii acquired in Brazil that had a fatal outcome, despite specific antibiotic therapy and valve surgery treatment.
