AmpC cephalosporinases in Escherichia coli

Medycyna Doświadczalna i Mikrobiologia, 2021
Escherichia coli is an important pathogen causing nosocomial infections. A significant problem in the treatment of infections caused by these microorganisms is their increasing resistance to β-lactam antibiotics, including third and fourth generation cephalosporins.

Prevalence, Characteristics and Clonal Distribution of Extended-Spectrum β-Lactamase- and AmpC β-Lactamase-Producing Escherichia coli Following the Swine Production Stages, and Potential Risks to Humans

Frontiers in Microbiology, 2021
The worldwide spread of extended spectrum β-lactamase (ESBL)- and AmpC β-lactamase (AmpC)-producing Escherichia coli poses serious threats to public health. Swine farms have been regarded as important reservoirs of ESBL/AmpC-EC.

Evaluation of the AID AmpC line probe assay for molecular detection of AmpC-producing Enterobacterales

Journal of Global Antimicrobial Resistance, 2019
In this study, the commercially available AID AmpC line probe assay (LPA) was evaluated for detection of plasmid-mediatedblaAmpC β-lactamase genes in Enterobacterales as well as chromosomal mutations in the blaAmpC promoter/attenuator regions in Escherichia coli.Accuracy of the AID AmpC probes was assessed using Enterobacterales clinical isolates ...

Incidence of fecal Enterobacteriaceae producing broad-spectrum beta-lactamases in patients with hematological malignancies

Biomedical Papers, 2015
Aim: Given the steadily increasing numbers of resistant bacteria, the frequency and severity of infections are on the rise. In patients with hematological malignancies, the treatment itself increases the risk of complicating bacterial infections.

Docking for fragment inhibitors of AmpC β-lactamase [PDF]

Proceedings of the National Academy of Sciences, 2009
Fragment screens for new ligands have had wide success, notwithstanding their constraint to libraries of 1,000–10,000 molecules. Larger libraries would be addressable were molecular docking reliable for fragment screens, but this has not been widely accepted.
