Antimicrobial Susceptibilities, Its Resistance Mechanisms, Virulence Determinants and Phylogenetic Groups of Escherichia coli Isolated From Different Clinical Animal Samples
Περίληψη
Escherichia coli is a versatile agent, as some are commensals, normally living in the intestines of both
humans and animals, while others are pathogenically responsible for a wide variety of intestinal and extra-intestinal infections
including urinary tract infections (UTIs), meningitis, septicemia, bovine mastitis and colibacillosis in poultry.
The present study aims to determine the antimicrobial susceptibilities, its underlying genetic resistance mechanisms,
distribution of phylogroups, and virulence determinants of 42 E. coli isolates from different clinical sources of animals.
Our results have revealed that phylogroup A1 (42.9%) and B1 (40.5%) were the most prevalent phylogenetic groups
with different virulence profiles and varying incidence of virulence determinants. High rates of resistance to different
categories of antimicrobial agents with high rate of MDR (59.5%). Phylogenetic analysis showcased remarkable diversity
among the tested isolates, with no discernible clustering based on antimicrobial resistance or virulence patterns.
Our research has demonstrated the significant phylogenetic diversity of E. coli isolated from different clinical samples.
E. coli isolates are endowed with various virulence factors that contribute to their pathogenesis in animals. The elevated
rates of antimicrobial resistance and emergence of MDR mirror the trend detected globally in recent years.
