EcoliTyper: a species-optimized computational pipeline for comprehensive genotyping and surveillance of Escherichia coli.
Article in BMC bioinformatics, 2026. 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
backgroundEscherichia coli is a major bacterial pathogen associated with a high global burden of disease. Effective surveillance requires integrated genomic analysis, but current methods rely on multiple independent tools for sequence typing, serotyping, plasmid screening, and profiling of antimicrobial resistance (AMR) and virulence factors. This fragmented workflow could complicates analysis and hinders standardized reporting.
resultsWe developed EcoliTyper, a computational pipeline that executes a comprehensive set of E. coli genotyping analyses in a single automated workflow. The tool performs species confirmation (via fastANI), assembly quality control, Multi-Locus Sequence Typing (MLST), serotyping (O and H antigens), CH typing (FumC and FimH), Clermont phylogrouping, pathotype classification, and screening for AMR genes, virulence factors, plasmid replicons, biocide and heavy metal resistance markers. It includes cross-genome pattern discovery to summarise gene frequencies and contextualises results using a manually curated lineage database of high-risk clones. All results are compiled into an interactive, gene-centric HTML report, together with TSV, JSON, and plain text files. On a system with 16 CPU cores, EcoliTyper processed 60 E. coli genomes in approximately 129 min. AVAILABILITY: EcoliTyper is freely available under the MIT license at https://github.com/bbeckley-hub/EcoliTyper and is distributed as a self-contained Conda package.
conclusionEcoliTyper addresses workflow fragmentation in E. coli genomics by integrating multiple typing methods into a single, efficient pipeline. By providing structured, multi-format outputs and contextual data, it facilitates rapid isolate characterisation for surveillance and epidemiological studies.
