Recent refinements simplify methods for P22 transduction in Salmonella and allow improved recovery of phage-free transductional clones. The methods include use of: integration- and lysis-defective phage mutants, heat-killed bacteria to eliminate free phage, direct plating of phage and bacteria, replica-plating for detection of phage content of individual clones, improved broth for phage growth, and procurement of high titer phage from P22 lysogens.
