The role of New World vultures as carriers of environmental antimicrobial resistance.
Article in BMC microbiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlthough antibiotics have significantly improved human and animal health, their intensive use leads to the accumulation of antimicrobial resistance (AMR) in the environment. Moreover, certain waste management practices create the ideal conditions for AMR development while providing predictable resources for wildlife. Here, we investigated the role of landfills in the potentiation of New World vultures to disseminate environmental AMR. We collected 107 samples (soil, water, and feces) between 2023 and 2024, in different bird use sites (roosts, landfills and boneyards).
resultsWe isolated enterococci (EN), Escherichia coli (EC), and Salmonella spp. (SM), performed antibiotic susceptibility tests, and quantified the presence of antibiotic resistance genes (ARGs) within all samples. We identified EN, EC, and SM, in 50, 37, and 26 samples, from the three vulture use areas, respectively. AMR was mainly to aminoglycoside, cephalosporin, and tetracycline, and the prevalence of multidrug resistance (MDR) was 5.3% (EC), 78.2% (EN), and 17.6% (SM). Variations in bacterial abundance and AMR/MDR profiles were found based on the season, use site, and sample types, which was corroborated by ARG analyses.
conclusionsOur study suggests that landfills constitute a source of zoonotic pathogens and AMR for wildlife, due to readily available refuse input. Using non-invasive molecular methods, we highlight an often-ignored ecosystem within the One Health paradigm.
