Utilization of 16S Ribosomal DNA Sequencing for Diagnosis of Septicemia Due to Neisseria elongata subsp. glycolytica in a Neutropenic Patient

摘要

Septicemia due to Neisseria elongata subsp. glycolytica occurs infrequently. We report a case of septicemia in a patient undergoing antimitotic chemotherapy. Gram-negative coccobacilli were isolated from blood cultures. The identity of the isolate by phenotypic methods was uncertain. In contrast, identity was confirmed by 16S ribosomal DNA sequencing, which appeared to be very useful for correct identification.
