Cefclidin is a fourth-generation cephalosporin antibiotic effective against a clinical strain of Citrobacter freundii. The affinity of cefclidin for the β-lactamase isolated from these mutants was lower than that of ceftazidime, and the kinetic parameters of enzymatic hydrolysis showed that cefclidin was hydrolyzed more slowly at a low concentration than was ceftazidime. It is suggested that the high activity of cefclidin against strains derepressed for β-lactamase plays a major role in the absence of emergence of resistant mutants.
