comparison of the 50 % inhibition values for the antibiotics against the penicillin-binding proteins of the two strains with the minimal inhibitory concentrations for the same compounds indicates that methicillin , cloxacillin , 1078/1/1 , and to a lesser extent penicillin g , owe their poor antibacterial activity to exclusion from the bacterial cell , whereas cephaloridine is not excluded and is equally active against both the mutant and its wild type .
