Abstract Anthropogenic environments such as wastewater treatment plants (WWTPs) and landfills are sources of antimicrobial resistance (AMR). Black-headed gulls ( Chroicocephalus ridibundus) frequently use WWTPs may be vectors for AMR. We used GPS tracking data 39 up to 8 months, combined with a shedding curve, study dispersal distances AMR in Iberia. The 21 different (684 visits) three (21 visits). Areas high risk dissemination were an average 25 km from the infection source, maximum 500 km. Solar saltworks natural waterbodies particularly exposed dissemination, followed by agriculture, sports facilities, tourist beaches. There was important variability between individual their habitat specialization, which they visited. Studying spatial movements after visiting helps pinpoint sensitive locations where pathogen transmission is most likely.

ABSTRACT The emergence, spread and potential zoonotic importance of pathogenic‐resistant bacteria (e.g., Escherichia coli ) has fuelled the research on epidemiology vector movement dynamics. However, little is known about effects that apparently asymptomatic carriage may have host behaviour. Here, we analysed compared patterns habitat use (focused different risk exposure to Antibiotic Resistance) yellow‐legged gulls ( Larus michahellis carrying n = 10) not 29) Antibiotic‐resistant . Using data from GPS devices coupled with accelerometers, found evidence individuals resistant E. , although previously considered asymptomatic, had lower accumulated travelled distances moved over smaller areas. resistance affect some extent, as in this case, potentially reducing pathogen dispersal large

Gulls commonly rely on human-generated waste as their primary food source, contributing to the spread of antibiotic-resistant bacteria and resistance genes, both locally globally. Our understanding this process remains incomplete, particularly in relation its potential interaction with surrounding soil water. We studied lesser black-backed gull, Larus fuscus, a model examine spatial variation faecal bacterial communities, antibiotic genes (ARGs), mobile genetic elements (MGEs) relationship water soil. conducted sampling campaigns within connectivity network different flocks gulls moving across functional units (FUs), each which represents module highly interconnected patches habitats used for roosting feeding. The FUs vary habitat use, some using more polluted sites (notably landfills), while others prefer natural environments (e.g., wetlands or beaches). Faecal communities from that visit spend time landfills exhibited higher richness diversity. microbiota showed high compositional overlap was greater when compared landfill (11%) than wetland soils (6%), much lower (2% 1% water, respectively). relative abundance ARGs MGEs were similar between FUs, variations observed only specific families MGEs. When exploring carriage bird faeces compartments, gull enriched classified High-Risk. results shed light complex dynamics wild populations, providing insights into interactions among movement feeding behavior, characteristics, dissemination determinants environmental reservoirs.
