Diversity of ESBL-producing E. coli in various water and sediment types.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 is a major global health threat, and aquatic ecosystems serve as critical interfaces between human activity and the environment, providing reservoirs and pathways for the spread of resistant bacteria. In this study, we investigated the prevalence and diversity of ESBL-producing Escherichia coli across multiple aquatic environments in Slovenia by analysing water, sediment, and wastewater treatment plant (WWTP) influent samples collected between June 2023 and April 2024. ESBL-producing E. coli was detected in 93% of WWTP influents, 61% of water, and 35% of sediment samples. From 315 positive samples, 564 isolates were subjected to whole genome sequencing. In total, 134 MLST-sequence types (STs) were identified, with globally prevalent lineages (ST131, ST38, ST10, ST69, ST1193) occurring across regions and sample types. Clonally related isolates occurred in geographically distant sites, and persistent strains were observed over time, suggesting both local persistence and broader dissemination. Fourteen distinct ESBL genes were detected, predominantly plasmid-encoded blaCTX-M-15. Water samples captured the greatest ST diversity, whereas sediment and WWTP influents provided complementary insights. Combining sample types improved detection of overall diversity, with water and sediment or WWTP samples providing the most comprehensive overview. Our findings demonstrate widespread and dynamic dissemination of ESBL-producing E. coli in Slovenian aquatic environments and emphasize the value of integrated sampling strategies for effective surveillance.
