Leptotrichia species are fastidious anaerobic, fusiform, pencil-shaped Gram-negative bacilli that reside in microbiota of humans. Leptotrichia species have increasingly been recognized as an opportunistic pathogen in humans, mainly in the immunocompromised patient. Anaerobic organisms have rarely been isolated from blood cultures of pediatric patients. In our study, we isolated Leptotrichia trevisanii from central venous catheter culture of a five-year-old male patient. It was identified with both matrixassisted laser desorption ionization time-of-flight mass spectrometry and confirmed via 16S rRNA gene sequencing. The early recognition of anaerobic bacteremia and administration of appropriate antimicrobial and play an important role preventing mortality and morbidity in children. In our study we report a rarely diagnosed case of L. trevisanii bacteremia in a pediatric patient.
