Screening for ESBL production by the disc diffusion test and screening for AmpC production by the cefoxitin disc test

(A): An ESBL-producing E. coli isolate showing resistance to (CAZ), (CPO), (CTX), (ATM) and (CRO). The organism was sensitive to cefoxitin (FOX) indicating that the isolate is a non-AMPC-producer.

(B): An AMPC-producing A. baumannii isolate showing resistance to cefoxitin disc (FOX).
