by comparing the responses of otherwise isogenic p. aeruginosa beta-lactamase inducibility mutants to antipseudomonal cephalosporins alone or in combination with potent beta-lactamase inducers we confirmed that resistance to cefotaxime , ceftriaxone , cefoperazone , and ceftazidime and latamoxef was caused by beta-lactamase action .
