Ufr/s variation in Escherichia coli K12: a reversible double-mutation or alternate chromosome expression in non-complementing diploids?

Research in microbiology - 1 May 1994

Gratia J P

Abstract excerpt

A novel form of bacterial variation found in an FhuA- mutant of Escherichia coli K12 was characterized by the alternation of (1) simultaneous resistance to lipopolysaccharide-specific phage U3 and to FhuA-specific agents (Ufr phenotype); and (2) a return to the sensitivity pattern of the initial strain (Ufs). In Ufr cells, loss of the U3 receptor permitted C21 adsorption without modifying the sensitivity to other...
