[Isolation and characterization of Escherichia coli strains sensitive to hydrophilic and/or charged antibiotics and toxics (author's transl)].

Two Escherichia coli mutant strains sensitive to antitumor derivatives of ellipticinium, ethidium bromide and to a variety of hydrophilic antibiotics and toxics have been isolated. The two mutations have been mapped on the bacterial chromosome at 5 +/- 1 and 10 +/- 1 mn respectively. Some properties of these strains are described and their interest in… CONTINUE READING
