title: Roseomonas bacteremia in a recipient of an allogeneic hematopoietic stem cell transplantation.
abstract: Roseomonas are pink-pigmented, oxidative, slowly growing, nonfermentative, gram-negative coccobacilli whose identification may require extensive biochemical testing and molecular profiling. Roseomonas infections vary in severity and clinical presentation, and they predominantly occur in immunocompromised and chronically ill patients. The organism is generally susceptible to carbapenems and aminoglycosides, but resistant to most of the cephalosporins and broad-spectrum penicillins. Reported here is a patient with lymphoblastic lymphoma who developed Roseomonas mucosa bacteremia after receiving her hematopoietic stem cell allograft. The bacteremic episode was successfully treated with imipenem and amikacin in addition to removal of the central venous catheter. To our knowledge, this is the first report of Roseomonas bacteremia in a stem cell transplantation recipient.
