Escherichia coli K12 regains its O antigen.

Microbiology (Reading, England) - 1 Jan 1994

Liu D, Reeves P R

Abstract excerpt

Extant Escherichia coli K12 strains are phenotypically rough, their lipopolysaccharide having a complete core structure, but no O antigen. We used DNA hybridization and DNA sequencing to show that the rough phenotype of this strain is due to the presence of one of two independent mutations in the rfb gene cluster. The rfb-50 mutation, consisting of an IS5 insertion at the downstream end of rfb, is present in...
