Infectious endocarditis due to Bacillus Cereus in a patient with a pacemaker

Abstract

Introduction: Infective endocarditis (IE) is an infectious process of the cardiac endothelium, often related to the use of pacemakers and valve prostheses, which may facilitate microorganism” proliferation. Case Report: In this article, we describe the case of an 81-year-old man with infective endocarditis due to Bacillus Cereus related to the use of a pacemaker and perform a brief literature review. Discussion: Bacillus Cereus is a Gram-positive, aerobic, spore-forming, large, and generally motile bacterium that constitutes a rare cause of endocarditis, but few cases like this are described in the literature. Conclusion: Determining the etiology of IE through culture-guided methods plays a pivotal role in selecting appropriate antibiotic treatment. Maintain a high clinical suspicion for IE is paramount, especially when fever arises in patients with cardiac devices after surgical or dental procedures.
