Comparative pangenome analysis of Yersinia enterocolitica in a one health approach.
Article in BMC 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
Yersinia enterocolitica is a Gram-negative pathogen frequently associated with swine and pork products. Despite its global importance, little is known about the genomic characteristics of Y. enterocolitica in Brazil. Furthermore, the antimicrobial resistance (AMR) in Y. enterocolitica has been associated to be driven by horizontal gene transfer, especially in environments with intensive antimicrobial use. This study aims to investigate the phylogenetic and population structure of Y. enterocolitica, and antimicrobial resistance and virulence gene distribution using genome sequences to compare isolates obtained in Brazil with other isolates deposited in online databases. In this study, a total of 998 high-quality genomes from Y. enterocolitica deposited in the National Center for Biotechnology Information (NCBI) were evaluated for pangenome using the Roary software with MAFFT for alignment. Pangenome analysis and phylogenetic inference were also performed on a subset of 837 genomes from isolates obtained from both pig and human. The analyses followed the procedures determined by ModelTest-NG. ABRicate with PlasmidFinder database, Virulence Factor Database (VFDB) and CARD database were used to investigate plasmid markers, virulence genes and resistance genes. Comparative analysis with international strains from public databases suggests that specific Y. enterocolitica strains circulate in Brazil. Swine and human isolates from Brazil were consistently grouped together, suggesting a strong zoonotic link. Additionally, the study underscores the correlation between antimicrobial use in pig farming and resistance gene prevalence. Our findings contribute to the understanding of Y. enterocolitica epidemiology in Brazil and emphasize the importance of genomic surveillance under the One Health approach to prevent foodborne diseases and combat antimicrobial resistance.
