Resistomes

Prevalence of Mycolicibacterium smegmatis 16S rRNA (rrsB) mutation conferring resistance to kanamycin A among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI for 88 important pathogens (see methodological details and complete list of analyzed pathogens). Values reflect percentage of genomes, plasmids, or whole-genome shotgun assemblies that have at least one hit to the AMR detection model. Default view includes percentages calculated based on Perfect plus Strict RGI hits. Select the checkbox to view percentages based on only Perfect matches to AMR reference sequences curated in CARD (note: this excludes resistance via mutation as references in protein variant models are often wild-type, sensitive sequences).

Detection Models

Model Type: rRNA gene variant model

Model Definition: The rRNA gene variant model is an AMR detection model used to identify ribosomal RNA (rRNA) genes with mutations shown clinically to confer resistance to known antibiotic(s) relative to the wild-type rRNA sequence. Like the protein variant model, rRNA gene variant models detect the presence of an rRNA sequence based on its homolog, and then secondarily search submitted query sequences for a curated mutation. This model includes an rRNA gene reference sequence, a BLASTN bitscore cutoff, and a set of mapped resistance variants. A submitted sequence must have both high homolog to the reference sequence and include a known resistance variant to be detected.

Bit-score Cut-off (blastN): 2700
