Key Points

The research aimed to assess virulent factor genes in pig-derived Escherichia coli and evaluate treatment options.
Taxonomic identification of E. coli using MALDI-TOF mass spectrometry.
Detection of virulence factor genes fimA and Crl in E. coli strains.
Evaluation of biofilm formation and antibiotic resistance among the strains.
Testing susceptibility of E. coli strains to herbal essential oils and postbiotic substances.
62.5% of strains were positive for the fimA gene.
87.5% of strains contained the Crl gene.
Five E. coli strains were confirmed as biofilm-forming.
Strains displayed multiresistance to antibiotics.
Average inhibitory zones against herbal oils ranged from 15 to 27 mm.
