Detection of optrA and poxtA genes in linezolid-resistant Enterococcus isolates from fur animals in China

Letters in Applied Microbiology, 2022
Abstract The emergence of linezolid-resistant (LR) enterococci found in food of animal origin arouses attention, but little is known about LR enterococci in fur animals. A total of 342 Enterococcus faecalis and 265 E. faecium strains isolated from fur animals in China from 2015 to 2017 were investigated to determine if LR enterococci ...

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 ...

Impacts of florfenicol on the microbiota landscape and resistome as revealed by metagenomic analysis. [PDF]

, 2019
BACKGROUND:Drug-resistant fish pathogens can cause significant economic loss to fish farmers. Since 2012, florfenicol has become an approved drug for treating both septicemia and columnaris diseases in freshwater fish.

Identification of Outer Membrane Vesicles as a New Vehicle Mediating Antibiotic Resistance Gene Transfer in Campylobacter

Journal of Extracellular Vesicles, Volume 14, Issue 11, November 2025.
ABSTRACT The emergence and worldwide dissemination of antibiotic resistance genes (ARGs) compromise antibiotic therapy and are a major public health crisis. Horizontal gene transfer (HGT) plays a major role in the spread of ARGs among bacterial pathogens.

Antibiotic Resistance: A Genetic and Physiological Perspective

MedComm, Volume 6, Issue 11, November 2025.
The development of resistance to antimicrobials and their historical progression are depicted in this graphic. It draws attention to important biochemical, physiological, and genetic factors that contribute to AMR, such as the transmission of genes, the development of biofilms, and the inactivation of antibiotics.

Spatio‐temporal characteristics of the gastrointestinal resistome in a cow‐to‐calf model and its environmental dissemination in a dairy production system

iMeta, Volume 4, Issue 4, August 2025.
This study revealed spatio‐temporal characteristics of gastrointestinal resistome in a cow‐to‐calf model and the pattern of their spread to the environment and offspring in the dairy production system. The gastrointestinal tract of dairy cows is a natural reservoir of resistomes and distinguished by gut sites and regions.

Emergence and Genomic Characterization of the First Reported optrA-Carrying Linezolid-Resistant Enterococci Isolated from Retail Broiler Meat in the United Arab Emirates

Foods, 2022
The foodborne transfer of resistant genes from enterococci to humans and their tolerance to several commonly used antimicrobials are of growing concern worldwide.
