Human wastewater contamination drives the emergence of multidrug-resistant bacteria in the Galápagos marine ecosystem.

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
Antimicrobial resistance poses a global threat to public health. Mobile microbiological laboratories can enable environmental monitoring of antimicrobial resistance, particularly in geographically remote and resource-limited locations, such as the Galápagos archipelago. Here, we report the development of a mobile laboratory for antimicrobial resistance surveillance of marine sites surrounding San Cristóbal, the archipelago's second most populated island, which has experienced rapid urbanization and intense international tourism pressure. On-site metagenomic sequencing of wastewater-contaminated marine sites reveals a stark shift in microbial genera and a higher count of antimicrobial resistance genes compared to uncontaminated marine sites, mirroring metagenomic results of local untreated sewage. Over 40% of lactose-fermenting Enterobacteriaceae isolates collected directly from sewage or marine environments near sites of wastewater outfall exhibit multidrug resistance. Long-read sequencing and de novo assembly of bacterial genomes and plasmids from multidrug-resistant Escherichia coli reveal frequent and rapid reassortment of antimicrobial resistance genes on plasmids, generating a diverse and functional resistome on the island. This study not only provides a framework for conducting antimicrobial resistance research in low-resource settings but also underscores the impact of wastewater contamination on the environmental antimicrobial resistance landscape and highlights potential threats to human and animal health.
