Fig. 1From: Evolutionary analysis of gyrA gene from Neisseria meningitidis bacterial strains of clonal complex 4821 collected in China between 1978 and 2016Neighbor joining phylogenetic tree of 226 gyrA gene sequences from Neisseria strains. Strain name is indicated as follows: species name-GB ID-strain ID-ST-CC-Serogroup-country of collection-year of collection-CIP resistance phenotype. Missing information is indicated by an empty space. For example, N.meningitidis-AM889136.1-alpha14-ST53-CC53-cnl-Germany-1999 S; Eikenella corrodens-CP034670.1-KCOM3110----South Korea-2017. The sequence names from CC4821 N.meningitidis strains are indicated in red font. The 77 sequences generated in this study are underlined. The sequences of 9 reference strains are indicated by a black dot. Bootstrap values > 70% are indicated. Bootstrap values < 70% are indicated in parenthesis when necessary. The 9 genetic groups identified in this study are indicated as bracketed vertical lines. CIP resistance phenotype is indicated with R for resistance, S for sensitive and I for intermediate resistance phenotypeBack to article page
