Overview

This study reveals multidrug-resistant E. coli with ESBL and virulence genes in poultry, suggesting risks for human transmission.

Key Points

  • A majority of E. coli isolates displayed multidrug resistance, including 72.1% classified as ESBL producers.
  • The most common resistance gene identified was blaCTX-M-G1, alongside significant rates of carbapenem resistance.
  • High prevalence of virulence genes like fimH, traT, and iutA were found in over 70% of the isolates.
  • The presence of class 1 and class 2 integrons in the majority of isolates signals a concerning trend in resistance transmission.
