Antibiotic resistance, virulence genes, and phylogenetic groups of bacteria isolated from wild passerine birds in Iran.

Wild passerine birds may serve as environmental reservoirs and as vectors for the long-distance dispersal of microorganisms and resistance determinants. However, there is no much knowledge on pathogenic bacteria in wild birds in Iran. The present study aimed to analyze antibiotic resistance in wild passerine birds collected from the northeast region of Iran as the rich breeding bird fauna with a special focus on Escherichia coli virulence, integron, and phylogenetic groups.
