AmpC and extended spectrum beta lactamase producing isolates of E. coli, Klebsiella spp. and P. mirabilis in a tertiary care center and their sensitivity to other antibiotics

Enterobacteriaceae cause protean infections and are the common Gram negative isolates in a microbiology laboratory. Spectrum of multi-drug resistance includes AmpC, Extended spectrum beta lactamase and carbapenemase production with others. This was a cross sectional study to determine susceptibility pattern of AmpC and extended spectrum beta lactamase producing isolates against different antimicrobials.
