Fig. 2From: The phylogenomic landscape of extended-spectrum β-lactamase producing Citrobacter species isolated from surface waterPangenome phylogenetic tree showing clustering of the quinolone resistance Citrobacter species strains (n = 42) as based on a maximum-likelihood phylogenetic tree. Approximately 13 qnrB genes were determined and clustering was based on MLST genome identification of the Citrobacter speciesBack to article page
