<i>Listeria monocytogenes</i> is a gram-positive bacterium commonly found in soil, water, and rotting vegetation. The most common presentation of a <i>Listeria </i>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 <i>L. monocytogenes</i> bacteremia. We described his evaluation, treatment, and clinical course. The patient was treated with IV ampicillin and discharged with trimethoprim-sulfamethoxazole.
