Abstract excerpt

Bacitracin resistance (bacitracin MIC, >/=256 microg ml(-1)) has been reported in Enterococcus faecalis, and in the present study we report on the genetic basis for this resistance. Mutagenesis was carried out with transposon Tn917 to select for E. faecalis mutants with decreased resistance to bacitracin. Two bacitracin-sensitive mutants (MICs, 32 microg ml(-1)) were obtained and Tn917 insertions were mapped to...
