In silico screening of epitopes as potential vaccine candidates against pathogenic Acinetobacter baumannii.
Article in Genes & genomics, 2025. 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
backgroundMultidrug-resistant (MDR) Acinetobacter baumannii (A. baumannii) poses a pressing threat to global healthcare settings, as most antibiotics are ineffective against this nosocomial pathogen. Vaccines, particularly peptide-based vaccines, offer a promising and effective strategy to deal with these infections.
objectiveThis study aimed to evaluate the potential of epitopes derived from the OmpA protein of A. baumannii as vaccine candidates for combating this pathogen.
methodsThis study employed advanced bioinformatic tools to identify potential epitopes for vaccine candidates against A. baumannii infections. IEDB and SYFPEITHI were used to identify T-cell epitopes of A. baumannii OmpA protein. The epitopes were filtered based on score, clustering, human similarity, immunogenicity, cytokine response, and safety. Epitopes with high scores and both class-I and class-II sites were selected. Three epitopes were chosen for molecular docking and physicochemical evaluation as potential vaccine candidates.
resultsThree epitopes (EP1, EP2, and EP3) derived from A. baumannii OmpA were found to effectively bind with specific human leukocyte antigen (HLA) alleles. These epitopes have shown promising potential to elicit both cellular and humoral immune responses. Their physicochemical and immunological properties were thoroughly evaluated, indicating strong antigenic potential, non-toxicity, lack of allergenic properties, good binding affinity, and wide population coverage. The epitopes' two- and three-dimensional structures were predicted, and they were docked with their respective HLA alleles to assess their ability to stimulate innate immune responses. The predicted epitopes and HLA-allelic complexes exhibited excellent binding affinity, optimal Root Mean Square Deviation (RMSD) values, favorable physicochemical properties, and high-quality structural characteristics.
conclusionsThis study identified epitopes that hold promise as potential solutions for combating multidrug-resistant A. baumannii, pending validation through wet lab experiments and clinical trials.
