Polymicrobial Peritonitis with Lactococcus lactis in a Peritoneal Dialysis Patient

초록

Lactococcus lactis (L. lactis) is an important gram-positive bacterium in dairy products. It is a rare cause of opportunistic infections with only four cases of Lactococcus peritoneal dialysis (PD) peritonitis reported in the literature. In Korea, L. lactis infection was first reported in a liver abscess patient in 2010; however, PD peritonitis with Lactococcus has not been reported in Korea. Recently, we experienced a case of Lactococcus-associated polymicrobial PD peritonitis. The patient was initially managed with broad-coverage antibiotics; however, owing to a poor response, the PD catheter was removed and the patient was switched to hemodialysis. We discuss this case and review the literature.
