A proposed scheme for the monitoring of antibiotic resistance in veterinary pathogens of food animals in the UK

Veterinary Record, Volume 189, Issue 3, 7/14 August 2021., 2021
Abstract Background: Antibiotic resistance in bacteria is a global threat to both animal and public health, and detecting its occurrence is an important component of control strategies. Monitoring programmes for antibiotic resistance are currently in place in food‐producing animals in the European Union covering the zoonotic bacteria Salmonella ...

Recombination events that occur in a poxtA-carrying Enterococcus faecium during the conjugation process

Journal of Antimicrobial Chemotherapy, 2022
Abstract Objectives To investigate transferability of the poxtA-carrying plasmids in Enterococcus faecium and the mechanism of recombination that occurs during the conjugation process. Methods MICs were determined by broth ...

Analysis of two pheromone-responsive conjugative multiresistance plasmids carrying the novel mobile optrA locus from Enterococcus faecalis [PDF]

, 2019
Background: The acquired optrA gene, which encodes a ribosomal protection protein of the ABC-F family, can confer cross-resistance to linezolid and florfenicol, posing a serious therapeutic challenge to both human and veterinary medicine.

Characterization of the resistome in Lactobacillus genomic sequences from the human gut

Journal of Global Antimicrobial Resistance, 2022
: Objectives: The gut is a complex environment inhabited by a wide range of bacterial species. Lactobacillus species constitute a significant proportion of this environment and, due to their mobile genetic elements such as plasmids and transposons, are ...

Detection of Oxazolidinone Resistance Genes and Characterization of Genetic Environments in Enterococci of Swine Origin, Italy

Microorganisms, 2020
One hundred forty-five florfenicol-resistant enterococci, isolated from swine fecal samples collected from 76 pig farms, were investigated for the presence of optrA, cfr, and poxtA genes by PCR.

Persistence of transferable oxazolidinone resistance genes in enterococcal isolates from a swine farm in China

Frontiers in Microbiology, 2022
The appearance of transferable oxazolidinone resistance genes poses a major challenge to public health and environmental safety. These genes not only lead pathogenic bacteria to become resistant to linezolid but also reduce sensitivity to florfenicol ...

Analysis of a poxtA- and optrA-co-carrying conjugative multiresistance plasmid from Enterococcus faecalis

Journal of Antimicrobial Chemotherapy, 2019
To investigate the presence and transferability of the poxtA gene and identify the genetic context of poxtA in two enterococcal plasmids from swine.MICs were determined by broth microdilution. A total of 114 porcine enterococci with florfenicol MICs of ≥16 mg/L were screened for the presence of the poxtA gene by PCR.

Florfenicol and oxazolidone resistance status in livestock farms revealed by short- and long-read metagenomic sequencing

Frontiers in Microbiology, 2022
Antibiotic resistance genes (ARGs) as a novel type of environmental pollutant pose a health risk to humans. Oxazolidinones are one of the most important antibiotics for the treatment of Gram-positive bacterial infections in humans.

Mechanisms of linezolid resistance among enterococci of clinical origin in Spain—detection of optrA-and cfr(D)-carrying E. faecalis [PDF]

, 2020
The mechanisms of linezolid resistance among 13 E. faecalis and 6 E. faecium isolates, recovered from six Spanish hospitals during 2017–2018, were investigated.
