Carriage of Extended-Spectrum-β-Lactamase- and AmpC-β-Lactamase-Producing Enterobacteriaceae (ESBL-PE) in Healthy Community and Outpatient Department (OPD) Patients in Nepal

Canadian Journal of Infectious Diseases and Medical Microbiology, 2020
Background. Extended-spectrum β-lactamase (ESBL)- and AmpC-β-lactamase-producing Enterobacteriaceae have recently emerged as a public threat in the treatment of nosocomial as well as community-acquired infections.

Identification of DHA-23, a Novel Plasmid-mediated and Inducible AmpC beta-Lactamase from Enterobacteriaceae in Northern Taiwan

Frontiers in Microbiology, 2015
Objectives: AmpC β-lactamases are classified as Amber Class C and Bush Group 1. AmpC β-lactamases can hydrolyze broad and extended-spectrum cephalosporins, and are not inhibited by β-lactamase inhibitors such as clavulanic acid.

In Vivo Resistance to Ceftolozane/Tazobactam in Pseudomonas aeruginosa Arising by AmpC- and Non-AmpC-Mediated Pathways

Case Reports in Infectious Diseases, 2018
Two pairs of ceftolozane/tazobactam susceptible/resistant P. aeruginosa were isolated from 2 patients after exposure to β-lactams. The genetic basis of ceftolozane/tazobactam resistance was evaluated, and β-lactam-resistant mechanisms were assessed by ...

Role of AmpR in the High Expression of the Plasmid-Encoded AmpC β-Lactamase CFE-1

mSphere, 2017
CFE-1 is a unique plasmid-encoded AmpC β-lactamase with the regulator gene ampR. It imparts high resistance to most cephalosporins with constitutive high-level β-lactamase activity.

Prevalence of Extended Spectrum β-Lactamase, Metallo β-Lactamase, and AmpC β-Lactamase among Gram Negative Bacilli Recovered from Burn Wound Infection

RUHS Journal of Health Sciences, 2023
Introduction: Infections are the major cause of morbidity and mortality in burn patients. The ESBL, MBL and AmpC are the major mediators of antimicrobial resistance in gram negative bacteria. Early detection of ESBL, MBL and AmpC β -lactamases is crucial

Detection of AmpC Beta-lactamases among Escherichia coli isolates at a tertiary care hospital in Karnataka [PDF]

Al Ameen Journal of Medical Sciences, 2013
Background & objective: AmpC β-lactamases are clinically significant because they may confer resistance to a wide variety of β-lactam drugs, including α-methoxy-β-lactams, such as cefoxitin, narrow-, expanded- and broad-spectrum cephalosporins, β-lactam ...

Occurrence and detection of AmpC β-lactamases among Enterobacteriaceae isolates from patients at Ain Shams University Hospital

Egyptian Journal of Medical Human Genetics, 2015
Background: AmpC β-lactamases are often plasmid mediated that hydrolyze all β-lactam antibiotics except cefepime and carbapenems. Aim of the study: We aimed to evaluate the presence of AmpC β-lactamase among Enterobacteriaceae isolates separated from ...
