Beyond bactericidal: targeting plasmid-mediated antibiotic resistance with natural product-based plasmid curing agents.
Review in Frontiers in microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 (AMR) has evolved into a severe global public health crisis, with plasmid-mediated horizontal gene transfer (HGT) serving as a core driver for the rapid dissemination of multidrug resistance (MDR). Traditional "bactericidal" antibiotic strategies impose strong selective pressure, failing to eradicate the root cause of resistance while accelerating the enrichment of resistant clones. "Plasmid curing"-a strategy that specifically eliminates resistance plasmids to restore antibiotic susceptibility-has emerged as a promising paradigm shift. While early synthetic curing agents suffered from severe cytotoxicity, natural products (e.g., alkaloids, quinones, terpenoids) exhibit unique potential owing to their structural diversity and multi-target profiles. This review systematically elucidates the molecular mechanisms by which natural products achieve plasmid eradication, including the disruption of Rep-ori replication initiation, interference with ParA-ParB partitioning dynamics, and the blockade of conjugation via type IV secretion system (T4SS) and quorum sensing (QS) inhibition. Crucially, we critically evaluate the methodological workflows-from high-throughput screening to absolute quantitative PCR-necessary to strictly differentiate true
