No standardized phenotypic methods for the screening and detection of plasmid-mediated AmpC enzymes are currently available, which is one of the main problems we are facing nowadays.
Aim: This study aimed to evaluate the presence of AmpC β-lactamase among Enterobacteriaceae isolates separated from patients with nosocomial infections and to detect the most prevalent genetic strains in the separated isolates and evaluation of two phenotypic methods (AmpC E test and cefoxitin–cloxacillin double disc synergy test) to detect AmpC enzymes.
Materials and methods: Total of 1200 gm negative isolates were screened for potential plasmid-mediated AmpC enzymes by cefoxitin disc, AmpC E test and cefoxitin–cloxacillin double disc synergy tests. The genotypic identificatio.. View More»
