title: Properties of an E. coli O26 mutant with modified cell wall and improved efficiency as recipient in conjugation for an FII plasmid.
abstract: Among populations of an E. coli O26 strain two types of mutants have been found to be present which act as better recipients in conjugation for an FII plasmid. Some properties of one of these mutants, O26SMB9, are here described. They indicate that a defect in the cell-wall structure has occurred which corresponds to a smooth----semirough transition.
