Direct selection for P1-sensitive mutants of enteric bacteria.

Abstract

A method has been developed to isolate mutants sensitive to coliphage P1 from bacterial genera normally not sensitive to this phage. P1clr100KM was used. This phage is heat inducible and confers kanamycin resistance when present as a prophage (in lysogens). P1-sensitive mutants of Klebsiella, Enterobacter, Citrobacter, and Erwinia have been found.
