Abstract
Coxiella burnetii is a gram-negative bacterium associated with serious complications such as infective endocarditis. Early diagnosis and treatment can be difficult due to its nonspecific presentation and risk factors that include contact with farm animals or their byproducts. Here, we present an atypical presentation of infective endocarditis caused by Coxiella burnetii, where the patient had no risk factors, negative Duke criteria, and negative preliminary workup.
