The increasing prevalence of resistance to the last-resort antibiotics carbapenems is leading to increasing difficulties in treating infections caused by multidrug-resistant carbapenem-resistant Gram-negative bacteria...
Background The extended spectrum 13-1actamase (ESBL)-producing Escherichia coil (E. coh) and Klebsiella pneumoniae (K. pneumoniae) are the major pathogens causing pneumonia and have a significant impact on the c...
Objective: To investigate the mechanism of carbapenem resistance and the occurrence ofplasmid-mediated quinolone resistance determinants qnr and aac(6')-Ib-cr in a clinical isolate of Enterobacter cloacae. Methods...
Bsckgroud AmpC β-lactamases and extended-spectrum β-lactamases (ESBLs) are becoming predominant causes of resistance to third and forth-generation cephalosporins in Klebsiella pneumoniae (K. pneumoniae). It is v...
