Brevundimonas diminuta coinfection as source of pyogenic liver abscess.

Brevundimonas diminuta, a non-fermenting gram-negative bacterium, is emerging as an important multidrug resistant opportunistic pathogen. It has been described in cases of bacteremia, pleuritis, keratitis and peritoneal dialysis-associated peritonitis. We describe, for the first time, a case of pyogenic liver abscess caused by coinfection of B. diminuta and Streptococcus anginosus, and briefly review pyogenic liver abscesses and the literature regarding B. diminuta.
