Role of Low-Molecular-Mass Penicillin-Binding Proteins, NagZ and AmpR in AmpC β-lactamase Regulation of Yersinia enterocolitica

Frontiers in Cellular and Infection Microbiology, 2017
Yersinia enterocolitica encodes a chromosomal AmpC β-lactamase under the regulation of the classical ampR-ampC system. To obtain a further understanding to the role of low-molecular-mass penicillin-binding proteins (LMM PBPs) including PBP4, PBP5, PBP6 ...

Rapid detection of plasmid-mediated AmpC-producers by eazyplex® SuperBug AmpC assay compared to whole-genome sequencing

Journal of Microbiological Methods
Current methods for plasmid-mediated AmpC β-lactamase (pAmpC) detection in routine microbiological laboratories are based on various phenotypic tests. Eazyplex®SuperBug AmpC assay is a molecular assay based on isothermal amplification for rapid detection of the most common pAmpC types from bacterial culture: CMY-2 group, DHA, ACC and MOX.

Database for the ampC alleles in Acinetobacter baumannii

PLOS ONE, 2017
Acinetobacter baumannii is a troublesome opportunistic pathogen with a high capacity for clonal dissemination. We announce the establishment of a database for the ampC locus in A. baumannii, in which novel ampC alleles are differentiated based on the occurrence of ≥ 1 nucleotide change, regardless of whether it is silent or missense.

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 ...

Molecular Study of Plasmid Genes Ampc of Acinetobacter baumannii Isolated from Clinical Cases Using Multiplex PCR

Journal of Mazandaran University of Medical Sciences, 2017
Background and purpose: Acinetobacter baumannii is an opportunistic pathogen that remains persistent in the environment for a long time. The eradication of this bacteria is difficult, since it has the ability to acquire antibiotic resistance. The aims of
