Listeria monocytogenes Bacteremia in an Individual With AIDS: A Case Report

Listeria monocytogenes is a gram-positive bacterium commonly found in soil, water, and rotting vegetation. The most common presentation of a Listeria infection is gastroenteritis. Invasive infection and severe complications are more common in immunocompromised hosts. Early identification and treatment of listeriosisis essential to reduce morbidity and mortality. This is a case report of a 50-year-old man with poorly controlled human immunodeficiency virus who presented with vague symptoms of chills and malaise. The patient was admitted for suspected pneumonia, later found to have L. monocytogenes bacteremia. We described his evaluation, treatment, and clinical course. The patient was treated with IV ampicillin and discharged with trimethoprim-sulfamethoxazole.
