Description

Abstract A fd clear plaque-forming mutant of Escherichia coli K37 has been isolated among progeny treated with N -methyl- N ′-nitroso- N -nitrosoguanidine. Although the growth of this mutant (CPF30) is strongly inhibited by fd infection, phage production is observed at a fairly good rate. This mutant is useful for fd plaque assays.
