title: A general method for selecting strains of Escherichia coli having altered spontaneous or induced mutabilities.
abstract: A simple method is described for selecting mutant strains of E. coli differing from their parent in the ability to spontaneously mutate via any mechanism. The method detects hypo- and hyper-mutators. It relies on the detection as papillae on thy colonies of second mutations either at the dra or drm locus.
