Fig. 2From: Mobilization of the nonconjugative virulence plasmid from hypervirulent Klebsiella pneumoniaeMobilization of pRJF293HA with the help of the IncF plasmid pRJBSI76-1. a XbaI PFGE and S1-PFGE of E. coli transconjugants and their parental strains. Full details of the strains are provided in Additional file 1: Table S1. Red triangles denote the virulence plasmid pRJF293HA. Blue triangles denote the IncF plasmid p1 or its derivative. The yellow triangle denotes the hybrid plasmid. Strains with the same symbol on the PFGE image represent progeny derived from the same parental strain. b, c Schematic diagram of the conjugation assays. The red square denotes the hph tag on the virulence plasmid pRJF293HA. The green rectangle denotes the tra gene cluster on the IncFIB plasmid p1Back to article page
