Abstract

The diagnostic utility of inducer and inhibitor based assays among 214 AmpC positive isolates of Pseudomonas aeruginosa were evaluated. Of different methods, combination of ceftazidime-imipenem antagonism and boronic acid inhibition tests came up with maximum sensitivity (76%) and specificity (100%). This combination showed reliability for both inducible and non-inducible AmpC producers.Copyright © 2011 Elsevier B.V. All rights reserved.
