A rapid detection of Avian Pathogenic Escherichia coli (APEC) strains based on minimal number of virulence markers identified by whole genome sequencing.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundColibacillosis is an important epidemiological and economic issue in poultry farming and breeding. A common problem with avian pathogenic Escherichia coli strains (APEC) that cause this disease is a lack of an uniform identification system, resulting from a variety of serotypes, phylogenetic groups, sequence types and combinations of virulence factors. There are no clearly defined features that can be associated with pathogenicity. Therefore, without precise identification of pathogenic strains and differentiation from commensal strains, there is no possibility of appropriate selection of targeted therapy. The widespread use of whole genome sequencing (WGS) in recent years creates new possibilities in diagnostics. Therefore, the purpose of this study was to select features defining the APEC pathotype, based on next generation sequencing (NGS), and design a diagnostic test based on selected factors.
resultsA PCR diagnostic test is proposed. Three predictors of virulence were chosen according to in silico analysis: two virulence genes: iroC and hlyF, as well as one molecular marker of O78 serotype (wzx-O-antigen flippase of the O78 serotype). A choice of markers was supported by a chicken embryo model.
conclusionsWhole genome sequencing of E. coli genomes allowed for the development of a rapid diagnostic method identifying pathogenic strains for poultry: APEC. The developed test can support field observations connected with the strain isolation source and clinical symptoms of the disease.
