Mutability in clinically cultured strains of Escherichia coli

The present work was undertaken to study the mutability in clinically cultured strains of Escherichia coil [E. coli]. The mutability studies were carried out by using two mutagens i.e. ultraviolet light and Ethyl Metnane Sulphonate [EMS]. The studies reveal that these clinically isolated strains do not differ significantly from other standard laboratory strains of E. coil. The mutability was enhanced from 10[-4] to 10[-2] by use of mutagens
