Plesiomonas shigelloides septicemia: case report and literature review.

A 13-year-old girl with Plesiomonas shigelloides septicemia is reported. The infection occurred while she was receiving an allogeneic bone marrow transplantation for acute promyelocytic leukemia. Treatment with ciprofloxacin was successful. Twenty-one cases of Plesiomonas septicemia have been reported in the literature. Immunocompromised hosts, especially neonates, are commonly affected. The case mortality rate is high, with 13 of the reported patients dying of the infection. Successful treatment relies on the early identification of the organism and implementation of effective antibiotics.
