Overview

Characterizes genetic diversity and antimicrobial resistance in Escherichia coli from dairy farms, indicating significant AMR reservoirs.

Key Points

  • This research aims to explore the genomic diversity and antimicrobial resistance profiles of E. coli from dairy farm environments.
  • Isolated E. coli from soil, effluent, cow dung, and milk samples
  • Performed DNA extraction, library preparation, and sequencing on the Illumina MiSeq platform
  • Conducted bioinformatic analysis to assess genomic data and identify ARGs
  • Identified 20 distinct sequence types, including one novel type
  • 71% of isolates contained plasmids, predominantly from the IncF family
  • Detected 12 ARG groups, with 67.7% of isolates showing β-lactam resistance genes
