Pantoea dispersa Causing Bacteremia and Endocarditis in an Immunocompromised Adult: A Rare Case

Gram-negative rods, namely, <i>Escherichia coli</i> and <i>Salmonella spp.</i>, are the most common causative agents of bacteremia. The genus <i>Pantoea</i>, another group of Gram-negative rods, is a relatively uncommon cause of bacteremia. Our literature review revealed only eight other cases of <i>Pantoea dispersa</i> infection in humans. In an otherwise healthy patient, <i>Pantoea</i> bacteremia is often transient and can be cleared with host immune defenses. Clearing of the bacteria may be complicated by an immunosuppressed state and infection with nidus. This is a case of bacteremia and endocarditis caused by <i>Pantoea dispersa</i> in an immunocompromised 75-year-old female.
