Genomic features, phylogenetic relationships, and comparative genomics of Elizabethkingia anophelis strain EM361-97 isolated in Taiwan

Elizabethkingia anophelis has become an emerging infection in humans. Recent research has shown that previous reports of E. meningoseptica infections might in fact be caused by E. anophelis. We aimed to investigate the genomic features, phylogenetic relationships, and comparative genomics of this emerging pathogen. Elizabethkingia anophelis strain EM361-97 was isolated from the blood of a cancer patient in Taiwan. The total length of the draft genome was 4,084,052 bp. The whole-genome analysis identified the presence of a number of antibiotic resistance genes, which corresponded with the antibiotic susceptibility phenotype of this strain. Based on the average nucleotide identity, the phylogenetic analysis revealed that E. anophelis EM361-97 was a sister group to E. anophelis FMS-007, which was isolated from a patient with T-cell non-Hodgkin’s lymphoma in China. Knowledge of the genomic characteristics and comparative genomics of E. anophelis will provide researchers and clinicians with important information to understand this emerging microorganism.
