Abstract

Lactobacillus jensenii is rarely reported as a cause of endocarditis in immunocompetent patients. We describe a case of Lactobacillus jensenii associated native valve endocarditis that was identified using matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) technology. While most Lactobacillus species are generally resistant to vancomycin, Lactobacillus jensenii is frequently susceptible, but treatment requires accurate susceptibility results followed by timely medical and surgical intervention. Probiotic use in patients can be a risk factor for infection with Lactobacillus species.
