Production of penicillinase
WebbWith penicillinase-producing strains of the low-resistance group, cefazolin, cefamandole, and cefmetazole induced PBP 2' production about 5-fold, while flomoxef induced production 2.4-fold or less. In contrast, penicillinase-negative variants of low-resistance strains produced PBP 2' constitutively in large amounts and induction did not occur. WebbWith penicillinase-producing staphylococci, at first sight it seems that the more resistant it is to penicil linase the more effective will a penicillin be.
