Conjugation of IncW and different plasmids when co-resident in donor bacteria. The result shows the mean of conjugation frequencies obtained from at least four independent experiments normalized to that in the absence of co-resident plasmids (

p < 0.001). IncW plasmid R388 was used in all matings, except when TpR plasmids pCTX-M3 or R751 were co-resident. In such case, IncW plasmid pIE321 was used. Inc, incompatibility group (Taylor et al., 2004). MOB, MOB relaxase group (Garcillan-Barcia et al., 2009). MPF, mating pair formation type (Guglielmini et al., 2011).
