Infective endocarditis (IE) is a life-threatening condition with adverse consequences and increased mortality, despite improvements in treatment options. Diagnosed patients usually require a prolonged course of antibiotics, with up to 40-50% requiring surgery during initial hospital admission. We report a case of a 42-year-old intravenous drug user who presented feeling generally unwell, with lethargy, rigours, confusion and a painful swollen right leg. He was subsequently diagnosed with Proteus mirabilis endocarditis (fulfilling modified Duke criteria for possible IE) and deep vein thrombosis (DVT). He was successfully treated with single antibiotic therapy without needing surgical intervention or requiring anticoagulation for his DVT. Proteus endocarditis is extremely uncommon, with a limited number of case reports available in the literature. This case illustrates how blood cultures are invaluable in the diagnosis of IE, especially that due to unusual microorganisms. Our case also highlights how single antibiotic therapy can be effective in treating Proteus endocarditis.

Infective endocarditis (IE) with Staphylococcus aureus is associated with intravenous drug abuse or infected cardiac devices and commonly presents with non-specific constitutional symptoms. A 53-year-old female presented to the hospital with back pain, altered mental status, fever, and tachycardia. Due to patient's lethargy and decline in respiratory effort, she was intubated and lumbar puncture was performed that revealed neutrophil-predominant leukocytosis of the cerebrospinal fluid. The patient was empirically started on ceftriaxone and vancomycin, and blood cultures were positive for methicillin resistant Staphylococcus aureus (MRSA). A chest X-ray demonstrated pulmonary congestion and an implanted pacemaker; furthermore, a transesophageal echocardiogram (TEE) revealed a vegetation on the atrial lead of the pacemaker. As the patient's condition improved after a few days, she was extubated and was able to provide a clear history. The source of her infection was a pus pocket around her pacemaker which was placed two months prior to her admission. As expected, the infection resolved with proper source control and antibiotic therapy.
