A Rare Case of Enterococcus gallinarum-Associated Peritonitis and Literature Review.

Peritonitis is a well-known complication seen with peritoneal dialysis. Peritonitis is associated with increased mortality risk and is commonly caused by gram-positive and gram-negative bacteria, but it can also be the result of fungal or viral infections. Therefore, it is imperative to obtain a peritoneal fluid sample to send for cell count with differential, gram stain, and culture prior to starting empiric antibiotic therapy. We report a case of peritoneal dialysis-related peritonitis caused by Enterococcus gallinarum, for which there has only been one other reported case in the medical literature. Our patient was initially placed on vancomycin and cefepime but continued to deteriorate until peritoneal fluid cultures revealed E. gallinarum. Based on sensitivities, the patient was treated with daptomycin and cefazolin, which resolved her peritonitis.
