Leptotrichia buccalis bacteremia in neutropenic children.

Two new cases of Leptotrichia buccalis bacteremia in seriously ill patients were described. The anaerobic, gram-negative microorganism L. buccalis was isolated from blood cultures of two children with severe leukopenia. Anaerobic organisms should be taken into account when a standard protective antibiotic chemotherapy is considered in the immunosuppressed host.
