Figure 4

Growth and survival curves in the mouse peritonitis model of E. faecium TX0016(pHyl EfmTX16 ) and TX1330RF(pHyl EfmTX16 ), carrying an intact hyl Efm -region, and pHyl EfmTX16Δ7,534 (6 gene mutant of the hyl Efm -region). A, Survival curve of representative inoculum (5 inocula per experiment in two independent experiments) of TX0016(pHylEfmTX16) vs TX0016(pHylEfmTX16Δ7,534) in mouse peritonitis; B, growth curves of TX1330RF(pHylEfmTX16) vs TX1330RF(pHylEfmTX16Δ7,534) and a second transconjugant [TX1330RF(pHylEfmTX16Δ7,534)-TCII] obtained from the same mating experiment between TX16(pHylEfmTX16Δ7,534) and TX1330RF, expressed as optical density (A600) in brain heart infusion (BHI) broth (results of at least three experiments per strain). C and D, survival curves of TX1330RF(pHylEfmTX16) vs TX1330RF(pHylEfmTX16Δ7,534) obtained in the peritonitis model at different inocula in independent experiments performed at different days.
