mutations within the gene gidB confer low-level streptomycin resistance. gidB mutations emerge spontaneously at a high frequency of 0.000001 and, once emerged, result in vigorous emergence of high-level streptomycin-resistant mutants at a frequency more than 2000 times greater than that seen in wild-type strains |
