ONTOLOGIES:
Data on the four core ontologies underlying the CARD are provided in three formats: OBO,
TSV, and JSON. The Antibiotic Resistance Ontology is additional available in OWL format.
The ontologies are:
ARO - The Antibiotic Resistance Ontology that serves as the primary organizing principle
of the CARD.
MO - CARD's Model Ontology which describes the different antimicrobial resistance gene
detection models encoded in the CARD and used by the Resistance Gene Identifier.
NCBITaxon - A slim version of the NCBI Taxonomy used by the CARD to track source pathogen
of molecular sequences.
RO - CARD's Relationship Ontology which describes the different relationship types between
ontology terms.
VIRO - CARD's draft Virulence Ontology describing bacterial virulence. Currently not under
development.
CARD SHORT NAMES:
A CARD-specific abbreviation for AMR gene names associated with Antibiotic Resistance
Ontology terms, often not based on the literature. This is used for programmatic and
compatibility purposes and is not ontologically relevant. Each ontology term with an
associated AMR detection model has a CARD Short Name that appears in CARD data files
and output generated by RGI. If the original gene name is less than 15 characters, the
CARD short name is identical; if the gene name is greater than 15 characters, the CARD
Short Name has been abbreviated by CARD curators specifically to identify the proper
gene or protein name. All CARD Short Names are unique and have whitespace characters
replaced by underscore characters. The convention for pathogen names is capitalized
first letter of the genus followed by the lowercase first three letters of the species
name. The antibiotic abbreviations are from https://journals.asm.org/journal/aac/abbreviations
plus some custom abbreviations by the CARD curators. Simple CARD Short Names often do not
involve either, e.g. CTX-M-15, but where applicable the CARD Short Names follow pathogen_gene
or pathogen_gene_drug. The full lists of abbreviations can be found at:
