Septic shock caused by Sphingomonas paucimobilis bacteremia in a patient with hematopoietic stem cell transplantation.

Sphingomonas paucimobilis is an aerobic gram-negative bacillus that causes a variety of infections in healthy as well as in immunocompromised individuals. The organism is usually susceptible to tetracycline, chloramphenicol, aminoglycosides, trimethoprim-sulfamethoxazole, and carbapenems. However, resistance to penicillins and the first-generation cephalosporins is commonly encountered.
