Occurrence and genetic characteristics of third-generation cephalosporin-resistant Escherichia coli in Swiss retail meat.
Prevalence and genetic relatedness were determined for third-generation cephalosporin-resistant Escherichia coli (3GC-R-Ec) detected in Swiss beef, veal, pork, and poultry retail meat. Samples from meat-packing plants (MPPs) processing 70% of the slaughtered animals in Switzerland were purchased at different intervals between April and June 2013 and analyzed. Sixty-nine 3GC-R-Ec isolates were o...
متن کاملWGS-based surveillance of third-generation cephalosporin-resistant Escherichia coli from bloodstream infections in Denmark.
Objectives To evaluate a genome-based surveillance of all Danish third-generation cephalosporin-resistant Escherichia coli (3GC-R Ec ) from bloodstream infections between 2014 and 2015, focusing on horizontally transferable resistance mechanisms. Methods A collection of 552 3GC-R Ec isolates were whole-genome sequenced and characterized by using the batch uploader from the Center for Genomic ...
متن کاملThird-Generation Cephalosporin–Resistant Vibrio cholerae, India
Vibrio cholerae resistance to third-generation cephalosporins is rarely reported. We detected a strain that was negative for extended-spectrum β-lactamase and positive for the AmpC disk test, modified Hodge test, and EDTA disk synergy test and harbored the blaDHA-1 and blaNDM-1 genes. The antimicrobial drug susceptibility profile of V. cholerae should be monitored.
متن کاملGenomic Analysis of Third Generation Cephalosporin Resistant Escherichia coli from Dairy Cow Manure
The production of extended-spectrum β-lactamases (ESBLs) conferring resistance to new derivatives of β-lactams is a major public health threat if present in pathogenic Gram-negative bacteria. The objective of this study was to characterize ceftiofur (TIO)- or cefotaxime (FOX)-resistant Escherichia coli isolated from dairy cow manure. Twenty-four manure samples were collected from four farms and...
متن کاملCharacterization of Third-Generation-Cephalosporin-Resistant Shiga Toxin-Producing Strains of Escherichia coli O157:H7 in Japan.
We isolated Shiga toxin-producing Escherichia coli O157:H7 strains resistant to third-generation cephalosporins. The resistant strains harbored blaCMY-2, a plasmid-mediated AmpC β-lactamase. Genotyping of isolates revealed the possible spread of this problematic bacterium. Results suggested the importance of the investigation and surveillance of enterobacteria with plasmids harboring blaCMY-2.
