To investigate antibiotic resistance patterns in Escherichia coli from avian species and the influence of migratory behavior and local environments.
Collected 339 fecal samples from 44 avian species in Istanbul, Turkey.
Identified E. coli isolates using standard bacteriological methods and automated systems.
Conducted antimicrobial susceptibility testing using 16 agents across six antimicrobial classes.
Screened resistance genes via PCR and compared patterns based on migratory status.
E. coli was present in 46 samples (13.5% prevalence).
65.2% of isolates showed phenotypic resistance to at least one antimicrobial.
High levels of tigecycline minimum inhibitory concentrations were observed, indicating non-wild-type phenotypes.
No isolates were found resistant to colistin or meropenem, and none were classified as ESBL-producing or multidrug-resistant.
83.3% of resistance genes were found in isolates from resident or mixed-status birds.
