A Rare Case of Infective Endocarditis Caused by Aerococcus urinae.

Aerococcus urinae is an alpha-hemolytic gram-positive catalase-negative coccus that typically causes urinary tract infections. It has been rarely implicated in other invasive infections such as endocarditis, bacteremia, peritonitis, meningitis, and vertebral osteomyelitis. There are approximately 50 reported cases of A. urinae infective endocarditis in literature. We present a rare case of a 64-year-old male who was found to have a urinary tract infection, bacteremia, and endocarditis caused by A. urinae.
