This study investigates the genomic characteristics of canine and feline cefotaxime (CTX, a third-generation cephalosporin)-resistant Escherichia coli using the JVARM, Japanese Veterinary Antimicrobial Resistance Monitoring System, a nationwide monitoring. In this study, whole-genome sequencing (WGS) was performed on 51 canine and 45 feline CTX-resistant E. coli isolates, with certain isolates subjected to pulsed-field gel electrophoresis with S1 nuclease for plasmid-chromosome separation.

We investigated the prevalence of livestock-associated methicillin-resistant (LA-MRSA) in pig slaughterhouses from 2018 to 2022 in Japan and the isolates were examined for antimicrobial susceptibility and genetic characteristics by whole-genome analysis. Although the positive LA-MRSA rates on farms (29.6%) and samples (9.

Article Synopsis
  • The Japanese Veterinary Antimicrobial Resistance Monitoring System (JVARM) was set up to track antimicrobial-resistant bacteria in animals, specifically dogs and cats, from 2018 to 2020.
  • Investigations focused on antimicrobial resistance in certain bacterial species isolated from both healthy and diseased pets, with a total of 3256 isolates tested for susceptibility to various drugs.
  • Results showed significant resistance rates in diseased animals compared to healthy ones, highlighting concerns that antimicrobial use could lead to increased bacterial resistance in these communities.
