Lautropia mirabilis: An Exceedingly Rare Cause of Peritoneal Dialysis-Associated Peritonitis.

Lautropia mirabilis is a gram-negative coccoid bacterium isolated from oral and upper respiratory sites with unclear pathogenic potential. We present an exceedingly rare case of peritoneal dialysis-associated peritonitis due to L. mirabilis in a patient with a recent history of periodontal infection, successfully treated with intraperitoneal antibiotics. We propose that clinicians consider this organism as a potential cause of illness.
