Authored by Aldert Zomer, Sam Nooij, Cailean Carter, and Alison Mather (@alisonmather.bsky.social).
Supported by the JPIAMR MEGAISurv project: jpiamr.eu/projects/meg...
Thanks to all contributing to strengthening mutation-focused AMR surveillance in metagenomic data.
7/
The code is open-source, with both a web-based interface and the full repository available:
Web tool: klif.uu.nl/metapointfin...
GitHub: github.com/aldertzomer/...
Feedback on extending reference sets and integrating the approach into surveillance pipelines is welcome.
6/
We applied the tool to public datasets on fluoroquinolone, β-lactam, and rifamycin resistance, showing how mutation-level profiling resolves discrepancies between phenotypes and gene-only predictions.
5/
In benchmarks using simulated reads (100–5000 bp), MetaPointFinder outperformed existing mutation mappers and showed strong recovery of mutation-positive reads, particularly from long-read metagenomes.
4/
The outputs enable calculation of both relative abundance of mutation-driven AMR and the proportion of resistant reads among all reads mapping to a locus (WT + R). Metrics can be summarised at read, gene, or antibiotic-class level, extending metagenomic resistome profiling beyond gene presence.
3/
MetaPointFinder performs read-level protein and DNA alignment (DIAMOND + KMA) against curated AMRFinder mutation references. A custom scoring engine evaluates each substitution, enabling accurate detection across both long- and short-read datasets.
2/
In metagenomic data, most AMR tools detect only acquired genes, while point mutations in gyrA, parC, folA, rpoB, 23S rRNA and others are major drivers of resistance. These variants are rarely quantified because they require precise alignment and position-specific evaluation.
1/
Our preprint on MetaPointFinder is online:
www.biorxiv.org/content/10.6...
Current resistome profiling has a major gap: it misses mutation-driven AMR, even though chromosomal mutations underpin resistance to key antimicrobials. MetaPointFinder addresses this at the read level in metagenomes.
A new tool we’ve developed to identify AMR-associated SNPs in short- and long-read metagenome data….allows a greater understanding of the total resistome of a sample

I just made a first release of TNA - new tool to compare 2 bacterial genomes. Is shamelessly inspired by ACT, but should be simpler to use. Drag-n-drop two genomes: it runs BLAST for you and then you can visualize. For Mac, Windows 11, Linux tna.readthedocs.io
