Fig. 2From: Complete genome sequence and characterization of avian pathogenic Escherichia coli field isolate ACN001Phylogenetic tree highlighting the position of ACN001 relative to other strains within the Enterobacteriaceae family. The phylogenetic tree was constructed based on seven housekeeping genes (adk, fumC, gyrB, icd, mdh, purA, and recA) according to the aligned gene sequences using maximum likelihoods derived from MEGA software version 5. The scale bar represents the divergence time of different strains. Escherichia fergusonii (ATCC35469) was used as an out-groupBack to article page
