Escherichia coli may become resistant to cephamycines and oxyimino cephalosporins by virtue of promotor and attenuator mutations or because they have acquired mobilized beta-lactamases from other gram-negative bacilli. This study examined Canadian strains to determine how often promotor and/or attenuator mutations account for this mechanism of resistance and the extent to which clonal spread of these organisms...
