staramr (*AMR) scans bacterial genome contigs against the ResFinder, PointFinder, and PlasmidFinder databases (used by the ResFinder webservice and other webservices offered by the Center for Genomic Epidemiology) and compiles a summary report of detected antimicrobial resistance genes. The star|* in staramr indicates that it can handle all of the ResFinder, PointFinder, and PlasmidFinder databases.
Note: The predicted phenotypes/drug resistances are for microbiological resistance and not clinical resistance. This is provided with support from the NARMS/CIPARS Molecular Working Group and is continually being improved. A small comparison between phenotype/drug resistance predictions produced by staramr and those available from NCBI can be found in the tutorial. We welcome any feedback or suggestions.
For example:
staramr search -o out --pointfinder-organism salmonella *.fasta

To search a list of contigs (in fasta format) for AMR genes using ResFinder please run:
staramr search -o out *.fastaOutput files will be located in the directory out/.
To include acquired point-mutation resistances using PointFinder, please run:
staramr search --pointfinder-organism salmonella -o out *.fastaWhere --pointfinder-organism is the specific organism you are interested in (currently only salmonella, campylobacter, enterococcus faecalis and enterococcus faecium are supported).
To specify which PlasmidFinder database to use, please run:
staramr search --plasmidfinder-database-type enterobacteriaceae -o out *.fastaWhere --plasmidfinder-database-type is the specific database type you are interested in (currently only gram_positive, enterobacteriaceae are supported). By default, both databases are used.
To specify which MLST scheme to use, please run:
staramr search -o out --mlst-scheme senterica *.fastaWhere --mlst-scheme is the specific organism you are interested in (please visit the scheme genus map to see which are available). By default, it detects the scheme automatically.
To print information about the installed databases, please run:
staramr db info
If you wish to update to the latest ResFinder, PointFinder, and PlasmidFinder databases, you may run:
staramr db update --update-defaultIf you wish to switch to specific git commits of either ResFinder, PointFinder, or PlasmidFinder databases you may also pass --resfinder-commit [COMMIT], --pointfinder-commit [COMMIT], and --plasmidfinder-commit [COMMIT]. However, please note that because of compatibility issues arising from changes in the source databases, this functionality is largely unsupported and is unlikely to work for versions of the databases that StarAMR wasn't released with.
If you have updated the ResFinder/PointFinder/PlasmidFinder databases and wish to restore to the default version, you may run:
staramr db restore-default
The easiest way to install staramr is through Bioconda (we recommend using mamba as an alternative to conda).
conda install mamba # Install mamba to make it easier to install later dependencies
mamba create -c conda-forge -c bioconda -c defaults --name staramr staramrThis will install the staramr software at the most recent version within the conda environment named staramr. Bioconda will install all necessary dependencies and databases. Once this is complete you can run:
conda activate staramr # Activate conda environment
staramr --helpIf, instead, you wish to install staramr to the current conda environment you can run:
mamba install -c conda-forge -c bioconda -c defaults staramrYou should now be able to run staramr --help and recieve a usage statement.
You can also install staramr from PyPI using pip:
pip install staramr
However, you will have to install the external dependencies (listed below) separately.
If you wish to make use of the latest in-development version of staramr, you may update directly from GitHub using pip:
pip install git+https://github.com/phac-nml/staramrThis will only install the Python code, you will still have to install the dependencies listed below (or run the pip command from the previously installed Bioconda environment).
Alternatively, if you wish to do development with staramr you can use a Python virtual environment (you must still install the non-Python dependencies separately).
# Clone code
git clone https://github.com/phac-nml/staramr.git
cd staramr
# Setup virtual environment
virtualenv -p /path/to/python-bin .venv
source .venv/bin/activate
# Install staramr. Use '-e' to update the install on code changes.
pip install -e .
# Now run `staramr`
staramrDue to the way we packaged the ResFinder/PointFinder/PlasmidFinder databases, the development code will not come with a default database. You must first build the database before usage. E.g.
staramr db restore-default
- Python 3.7+
- BLAST+
- Git
- MLST 2.32.2+
By default, the ResFinder/PointFinder/PlasmidFinder genes listed in genes_to_exclude.tsv will be excluded from the final results. To pass a custom list of genes the option --exclude-genes-file can be used, where the file specified will contains a list of the sequence ids (one per line) from the ResFinder/PointFinder/PlasmidFinder databases. For example:
gene_id
gyrA_1_CP073768.1
pmrB_1_CP051284.1
Please make sure to include gene_id in the first line. The default exclusion list can also be disabled with --no-exclude-genes. Gene IDs must exactly match the FASTA record IDs provided in the source databases.
Complex mutations describe multiple point mutations that must be simultaneously present in order to confer resistance. One such example is the multiple pbp5 mutations that must be present in Enterococcus faecium in order to confer ampicillin resistance. These complex mutations may be specified by the user using a TSV-formatted file with the following format:
| positions | mandatory | phenotype |
|---|---|---|
| gene (mutation1), gene (mutation2) | gene (mutation1) | phenotype |
Where positions is all the point mutations to group into the complex mutation (optional and mandatory), mandatory is all the point mutations that must be present for the complex mutation to be reported (mandatory is a subset of positions), and phenotype is the phenotype that is conferred when this set of mutations is present. To see a specific example of this, please look at the default complex_mutations.tsv file included with StarAMR. The mutation will be reported in the pointfinder.tsv file similar to as follows:
| Isolate ID | Gene | Predicted Phenotype | CGE Predicted Phenotype | Type | Position | Mutation | %Identity | %Overlap | HSP Length/Total Length | Contig | Start | End | Pointfinder Position | CGE Notes | CGE Required Mutation | CGE Mechanism | CGE PMID |

The hits/ directory contains the BLAST HSP nucleotides for the entries listed in the resfinder.tsv and pointfinder.tsv files. There are up to two files per input genome, one for ResFinder and one for PointFinder.
For example, with an input genome named SRR1952908.fasta there would be two files hits/resfinder_SRR1952908.fasta and hits/pointfinder_SRR1952908.fasta. These files contain mostly the same information as in the resfinder.tsv, pointfinder.tsv, and plasmidfinder.tsv files. Additional information is the database_gene_start and database_gene_end listing the start/end of the BLAST HSP on the AMR resistance gene from the ResFinder/PointFinder/PlasmidFinder databases.

This software is still a work-in-progress. In particular, not all organisms stored in the PointFinder database are supported (only enterococcus_faecalis, helicobacter_pylori, enterococcus_faecium, campylobacter, escherichia_coli, salmonella are currently supported). Additionally, the predicted phenotypes are for microbiological resistance and not clinical resistance. Phenotype/drug resistance predictions are an experimental feature which is continually being improved.
staramr only works on assembled genomes and not directly on reads. A quick genome assembler you could use is Shovill. Or, you may also wish to try out the ResFinder webservice, or the command-line tools rgi or ariba which will work on sequence reads as well as genome assemblies. You may also wish to check out the CARD webservice.
Some ideas for the software were derived from the ResFinder, PointFinder, and PlasmidFinder command-line software, as well as from ABRicate and from SISTR (Salmonella In Silico Typing Resource) command-line tool .
Phenotype/drug resistance predictions are provided with support from the NARMS/CIPARS Molecular Working Group.
The Multi-locus sequence typing program is from the MLST Github.
