Genomic analysis of Neisseria elongata isolate from a patient with infective endocarditis.

ABSTRACT: Neisseria elongata is part of the commensal microbiota of the oropharynx. Although it is not considered pathogenic to humans, N. elongata has been implicated in several cases of infective endocarditis (IE). Here, we report a case of IE caused by N. elongata subsp. nitroreducens (Nel_M001) and compare its genome with 17 N. elongata genomes available in GenBank. We also evaluated resistance and virulence profiles with Comprehensive Antibiotic Resistance and Virulence Finder databases. The results showed a wide diversity among N. elongata isolates. Based on the pangenome cumulative curve, we demonstrate that N. elongata has an open pangenome. We found several different resistance genes, mainly associated with antibiotic efflux pumps. A wide range of virulence genes was observed, predominantly
