Phenotypic Detection of ESBL and AmpC producing Enterobacteriaceae isolated in a General Hospital

Journal of Microbiology and Infectious Diseases, 2018
Objective: The antibiotic resistance of Enterobacteriaceae is a worldwide preoccupation, and misuse antibiotics of beta-lactam group allowed the development of bacteria producing extended spectrum beta-lactamase and cephalosporinase AmpC enzymes type ...

Gene Families of AmpC-producing Enterobacteriaceae Present in the Intensive Care Unit of Cipto Mangunkusumo Hospital Jakarta

Indonesian Biomedical Journal, 2019
BACKGROUND: Antibiotic resistance has become a worldwide problem. Among Asia countries, Indonesia has high prevalence of multi-drug resistant organisms mainly due to Gram-negative bacilli Enterobacteriaceae.

Antibacterial Resistance Pattern in Clinical and Non-clinical Bacteria by Phenotypic and Genotypic Assessment

Journal of Pure and Applied Microbiology, 2021
Bacterial infections represent a very serious problem that threatens human health, antibiotics were designed to attack the causative agents of infectious diseases, but some bacterial pathogens became virulent and resistant to antibiotics by different ...

Multi-locus sequence typing of Escherichia coli isolates with acquired ampC genes and ampC promoter mutations [PDF]

Diagnostic Microbiology and Infectious Disease, 2016
Multi-locus sequence typing was used to reveal a high degree of diversity amongst the E. coli isolates with AmpC plasmid genes, and a high prevalence of the -32 mutation present.

Effect of ampC derepression on cefepime MIC in Enterobacterales with chromosomally encoded inducible AmpC β-lactamase [PDF]

Clinical Microbiology and Infection, 2019
We aimed to evaluate the effect of ampC derepression on the cefepime MIC in different species of Enterobacterales with chromosomally encoded inducible AmpC β-lactamase.We analysed a large number of wild-type/mutant pairs (n = 1030 in total). Cefepime MICs were determined by broth microdilution according to EUCAST recommendations.ampC derepression led ...

The AmpC phenotype in Norwegian clinical isolates of Escherichia coli is associated with an acquired ISEcp1-like ampC element or hyperproduction of the endogenous AmpC [PDF]

Journal of Antimicrobial Chemotherapy, 2008
The aim of the study was to examine resistance mechanisms associated with an AmpC phenotype in Norwegian clinical isolates of Escherichia coli.Clinical E. coli isolates (n = 106) with reduced susceptibility to third-generation cephalosporins without clavulanic acid synergy were collected from 12 Norwegian laboratories from 2003 to 2005.

ESBL and AmpC beta-lactamase-producing Enterobacteriaceae in poultry in the Czech Republic

Veterinární Medicína, 2010
A major reason for resistance of Enterobacteriaceae to beta-lactam antibiotics is production of ESBLs and AmpC beta-lactamases. As their more detailed description in poultry is unavailable in the Czech Republic, the presented study aimed at assessing ...

New Chromosomal AmpC β-Lactamase in Enterobacter cloacae [PDF]

Antimicrobial Agents and Chemotherapy, 2004
Several members of the Enterobacteriaceae, including Enterobacter spp., are naturally resistant to amoxicillin and cephalosporins. Enterobacter cloacae produces chromosomally encoded β-lactamases, also called cephalosporinases (1), and is a serious nosocomial pathogen, the third most prevalent bacterium isolated in intensive care settings (5, 8).
