Survival curves in the mouse peritonitis model of E. faecium TX1330RF and derivatives. A and B show survival curves of the TX1330RF(pHylEfmTX16Δ7,534) (6 gene mutant in the hyl
region) complemented with pAT392-derivatives (which include pAT392::hyl
-down) obtained in the peritonitis model at different inocula in independent experiments performed at different days. The asterisk indicates that the lines are superimposed since values are identical.
