Antimicrobial Agents and Chemotherapy, 2021 Linezolid is an important last-resort antibiotic for the treatment of multidrug-resistant enterococci. The aim of this study was to further characterize the genetic context of optrA and poxtA in 10 florfenicol-resistant enterococci isolated from flowing surface water. In most genomes,

Oxazolidinone resistance genes in florfenicol-resistant enterococci from beef cattle and veal calves at slaughter [PDF]
Frontiers in Microbiology, 2023 BackgroundLinezolid is a critically important oxazolidinone antibiotic used in human medicine. Although linezolid is not licensed for use in food-producing animals, the use of florfenicol in veterinary medicine co-selects for oxazolidinone resistance ...

Nasotracheal enterococcal carriage and resistomes: detection of optrA-, poxtA- and cfrD-carrying strains in migratory birds, livestock, pets, and in-contact humans in Spain [PDF]
European Journal of Clinical Microbiology & Infectious Diseases, 2023 AbstractThis study determined the carriage rates and antimicrobial resistance (AMR) genes of enterococci from nasotracheal samples of three healthy animal species and in-contact humans. Nasal samples were collected from 27 dog-owning households (34 dogs, 41 humans) and 4 pig-farms (40 pigs, 10 pig-farmers), and they were processed for enterococci ...
