K. pneumoniae C3091-derived RecA, GalET, ArcA and putative proteins KPN_01507/01508 confer enhanced GI colonisation to EPI100. Sets of mice were fed with equal amounts of EPI100 carrying the empty pACYC184 vector and EPI100 carrying pACYC184-recA, -galET, -arcA, or –kpn_01507/01508, respectively. In all four experiments, the bacterial counts of the control strain were below the detection limit of 50 CFU/g faeces (dashed horizontal lines) one-to-three days post-feeding. The data in Figure 4A-C are expressed as the mean ± SEM for three infected mice.
