Sensitivity to antimicrobial peptide A (SapA) contributes to the survival of Salmonella typhimurium against antimicrobial peptides, neutrophils and virulence in mice.
Article in Archives of microbiology, 2024. 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
Host-generated antimicrobial peptides (AMPs) play a pivotal role in defense against bacterial pathogens. AMPs kill invading bacteria majorly by disrupting the bacterial cell walls. AMPs are actively synthesized and released into the lumen of the gastrointestinal tract to limit colonization of enteric pathogens like Salmonella typhimurium (S. typhimurium). However, S. typhimurium has evolved several resistance mechanisms to defend AMPs. The multicomponent SapABCDF uptake transporter is one such system that helps in resisting AMPs. In the current study, we analyzed the role of S. typhimurium SapA against stress survival and virulence of this bacterium. ∆sapA mutant strain showed hypersensitivity to AMPs, like melittin and mastoparan. Further, ∆sapA mutant showed more than 22 folds (p = 0.019) hypersensitivity to neutrophils as compared to the WT strain of S. typhimurium. In addition, ∆sapA strain showed defective survival in mice. In conclusion, the results of the current study suggest that the SapA is essential for survival against AMPs and virulence of S. typhimurium.
