Evolutionary analysis of gyrA gene from Neisseria meningitidis bacterial strains of clonal complex 4821 collected in China between 1978 and 2016.

ABSTRACT:

Background

Neisseria meningitidis (N.meningitidis) bacteria belonging to clonal complex 4821 (CC4821) have been mainly reported in China and have been characterized by a high resistance rate to ciprofloxacin (CIP). The aim of this study was to assess the evolution of the DNA gyrase A (gyrA) gene from N.meningitidis CC4821 strains collected in China between 1978 and 2016. The complete sequence of gyrA gene from 77 strains are reported in this study and analyzed in the context of publicly available sequences from N. meningitidis of other CCs as well as other Neisseria species.

Results

The phylogenetic analysis of CC4821 gyrA gene reveals at least 5 distinct genetic clusters. These clusters are not CC4821-specific showing that gyrA evolution is independent of CC4821 evolution.
