Within One Health framework, the dissemination of antibiotic resistance genes (ARGs) and pathogenic bacteria by wild birds has attracted increasing attention. In this study, gut samples opportunistically collected in Tianjin, China, situated along East Asian-Australasian Flyway, were used to ascertain realistic distribution ARGs their intestinal tracts. These have different dietary habits (herbivore, carnivore, omnivore) residency statuses (resident migratory birds). Using 16S rRNA gene sequencing qPCR, we analyzed microbial communities abundance high-risk mobile genetic elements (MGEs). Birds with distinct ecological traits exhibited significant variations bacterial composition, yet similar diversity. Shigella sp. emerged as core pathogen, a mean relative 2.57 1,466 times higher than that other bacteria, its concentration correlated host's trophic level indicated δ15N values. The MGEs also varied bird traits. All 10 targeted detected carnivores or passage migrants, while carried significantly greater intI1 residents (p < 0.05). potential harbor disseminate cannot be ignored. Network analysis revealed blaTEM-1 presence multiple microorganisms, positively associated Clostridioides difficile, emphasizing risk potential. dfrA12 transmission across levels facilitated was observed. Our study underscores high posed carrying importance further research surveillance field.

Aeromonas spp. are common members of water and wastewater microbiomes, but some listed as opportunistic pathogens often reported to carry antimicrobial resistance (AMR) genes. We aimed assess the performance isolation media for capturing their distribution role in AMR dissemination into aquatic environments.
