Inhibition of Staphylococcus aureus and biofilm formation by the anthelminthic drug, triclabendazole.
Article in The Journal of antibiotics, 2022. 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
Triclabendazole (TBD) has been widely used in the treatment of helminthic infection. The anti-biofilm activity and antibacterial mechanism of TBD against Staphylococcus aureus were not known. Here, the anti-biofilm activity of TBD against clinical S. aureus isolates from China was systematically evaluated. Under TBD pressure, TBD-induced tolerant S. aureus with elevated TBD minimum inhibitory concentration (MIC) was selected in vitro and the genetic mutations between the parental isolates and TBD-induced tolerant derivatives were determined by whole-genome sequencing. TBD could significantly inhibit biofilm formation at sub-inhibitory concentration and disperse mature biofilm of clinical S. aureus isolates. In addition, TBD displayed bactericidal activity against the bacterial cells embedded in the biofilm and showed anti-persisters activity. Proteomic analysis showed that KEGG pathways of ABC transporters and beta-lactam resistance were significantly changed after TBD exposure. Moreover, SAUSA300_RS08395 (molecular chaperone DnaK), SAUSA300_RS11200 (sensor histidine kinase KdpD), SAUSA300_RS06325 (DNA translocase FtsK) were identified as candidate targets of TBD in S. aureus. Overexpression experiments further demonstrated that the elevated transcriptional level of DnaK resulted in S. aureus growth delay after exposure to a sub-MIC concentration of 1/2× MIC TBD. In conclusion, TBD exhibits antibacterial and anti-biofilm activity against S. aureus possibly by targeting the DnaK chaperone system.
