Overview

This work demonstrates antibiotic susceptibility in extraintestinal pathogenic E. coli from poultry, indicating human health risks.

Key Points

  • The aim is to characterize extraintestinal pathogenic E. coli (ExPEC) from human and poultry sources to understand their health implications.
  • Characterization of ExPEC for sanitizer tolerance, biofilm formation, antibiotic susceptibility, and adherence to Caco-2 cells.
  • Samples were isolated from poultry meat and human clinical collections.
  • Analyzed sanitizer tolerance and biofilm formation rates under specific test conditions.
  • Low sanitizer tolerance observed in 2.4% of ExPEC samples.
  • Biofilm formation was seen in 6% of samples.
  • Higher antibiotic susceptibility rates in human clinical ExPEC (55%) compared to poultry ExPEC (27.9%).
  • 62.8% of poultry ExPEC adhered to human intestinal epithelia like control E. coli O157:H7.
