title: Antibacterial activity of cefoperazone alone and in combination against cephalosporinase-producing Enterobacter cloacae.
abstract: The activity of cefoperazone against a strain with an inducible cephalosporinase and a mutant that produces the enzyme constitutively indicates that the low inducer activity of this antibiotic plays an important role in its activity against Enterobacter cloacae.
