Mycobacterium phocaicum bacteremia: an emerging infection in pediatric hematology-oncology patients.

Nontuberculous mycobacteria may cause central venous catheter-associated bacteremia. Between March 2011 and October 2013, 6 cases of Mycobacterium phocaicum bacteremia were found in the pediatric hematology-oncology department. All patients recovered. No positive blood culture was documented after removal of the central venous catheter. All 4 patients with pulsed field gel electrophoresis had the same pattern, different from the water sample, suggesting a common water source.
