Staphylococcus aureus biofilm extracellular DNA neutralizes the antimicrobial activity of histone H3.
Article in NPJ biofilms and microbiomes, 2026. 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
Staphylococcus aureus is an opportunistic pathogen that forms robust biofilms. This poses several challenges to the host in successfully clearing the pathogen, thus leading to chronic infections. S. aureus biofilms combat neutrophils by releasing pore-forming toxins called leukocidins. This leads to the induction of neutrophil extracellular traps (NETs) and neutrophil death. NETs are primarily composed of host DNA laced with several potent antimicrobials, including histones. While NETs entrap microbes, the nuclease produced by S. aureus degrades NETs, potentially releasing NET-associated antimicrobials. It is still unknown how S. aureus can persist in a chronic infection despite the presence of several NET-associated antimicrobials. Our studies revealed that histone H3 is sequestered by S. aureus-derived extracellular DNA (eDNA) of the biofilm matrix. This resulted in the architectural modification of the biofilm due to the formation of eDNA-H3 aggregates and protection of S. aureus within the biofilm from the potential bactericidal effects of H3.
