Fig. 1From: Prevalence and molecular characterization of oqxAB in clinical Escherichia coli isolates from companion animals and humans in Henan Province, ChinaDendrogram showing the genetic relatedness of 30 E. coli strains (oqxAB-positive). A phylogenetic tree for the seven housekeeping gene sequences was constructed using Phylip 3.69 software and their affinity relationships were described. Notes: Number “M” strains isolated from cats; Number “Q” strains isolated from dogs; Number “H” strains isolated from humans; ND, not determinedBack to article page
