This detailed book contains chapters using unbiased approaches such as chemical and transposon mutagenesis, as well as a protocol for allelic exchange, to make targeted mutants in Staphylococcus, as generating mutants of this bacteria can be accomplished in many ways, depending on the intended changes. Using these methods, the authors have been successful at making mutants that span individual single-nucleotide changes in the chromosome to whole genome mutant libraries. The latter strategy provides a useful tool for high-throughput screening, while single nucleotide changes are an...
