Several studies on AMRB in wildlife have been cross-sectional in design and sampled individual animals at only one point in time. To further understand the role of wildlife in maintaining and potentially transmitting these bacteria to humans and livestock, longitudinal studies are needed in which samples are collected from individual animals over multiple time periods. In Europe, free-ranging yellow-legged gulls (Larus michahellis) commonly live in industrialized areas, forage in landfills, and have been found to carry AMRB in their feces. Using bacterial metagenomics and antimicrobial resistance characterization, we investigated the spatial and temporal patterns of AMRB in a nesting colony of yellow-legged gulls from an industrialized area in southern France. We collected 54 cloacal swabs from 31 yellow-legged gull chicks in 20 nests on three dates in 2016. We found that AMRB in chicks increased over time and was not spatially structured within the gull colony. This study highlights the complex occurrence of AMRB in a free-ranging wildlife species and contributes to our understanding of the public health risks and implications associated with ARMB-carrying gulls living in anthropogenic areas. specialized antimicrobial resistance enterobacteria Larus third-generation cephalosporin whole-genome sequencing wild birds FRANCE 080 020 050 Ecology and Evolution 12 6 e8974 [10 ] 2022 2045-7758 https://www.documentation.ird.fr/hor/fdi:010085280 10.1002/ece3.8974 2045-7758 [F B010085280] https://www.documentation.ird.fr/hor/fdi:010085280 https://www.documentation.ird.fr/intranet/publi/2022-09/010085280.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-09-02 2025-02-24 fdi:010085280 fre
