Bacteremia caused by a novel isolate resembling leptotrichia species in a neutropenic patient.
We report a case of Leptotrichia species bacteremia in a patient undergoing treatment for acute myelogenous leukemia. Like previously reported Leptotrichia species, this is a gram-variable, pleomorphic rod that is catalase negative and utilizes glucose and sucrose. However, it is more fastidious than previously reported isolates of Leptotrichia and may represent a novel species.
