Fig. 4From: Comparative genomics reveals a lack of evidence for pigeons as a main source of stx2f-carrying Escherichia coli causing disease in humans and the common existence of hybrid Shiga toxin-producing and enteropathogenic E. coli pathotypesNeighbor-Joining phylogenetic tree of 157 stx2f-carrying E. coli isolates harbouring a BFP plasmid. The tree is based on the 14 genes of the BFP operon and the colours represent the various serotypes. Each isolate is indicated by the country of isolation, the year of isolation and its originBack to article page
