| CARD Short Name | sdiA |
| Definition | SdiA is a cell division regulator that is also a positive regulator of AcrAB only when it's expressed from a plasmid. When the sdiA gene is on the chromosome, it has no effect on expression of acrAB. |
| AMR Gene Family | resistance-nodulation-cell division (RND) antibiotic efflux pump |
| Drug Class | tetracycline antibiotic, phenicol antibiotic, glycylcycline, cephalosporin, rifamycin antibiotic, disinfecting agents and antiseptics, penam, fluoroquinolone antibiotic |
| Resistance Mechanism | antibiotic efflux |
| Efflux Component | efflux pump complex or subunit conferring antibiotic resistance |
| Efflux Regulator | protein(s) and two-component regulatory system modulating antibiotic efflux |
| Resistomes with Perfect Matches | Salmonella entericag+wgs |

Prevalence of sdiA among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI or IslandViewer for 413 important pathogens (see methodological details and complete list of analyzed pathogens). Values reflect percentage of genomes, plasmids, genome islands, 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).

Model Type: protein homolog model
Model Definition: Protein Homolog Models (PHM) detect protein sequences based on their similarity to a curated reference sequence, using curated BLASTP bitscore cut-offs. Protein Homolog Models apply to all genes that confer resistance through their presence in an organism, such as the presence of a beta-lactamase gene on a plasmid. PHMs include a reference sequence and a bitscore cut-off for detection using BLASTP. A Perfect RGI match is 100% identical to the reference protein sequence along its entire length, a Strict RGI match is not identical but the bit-score of the matched sequence is greater than the curated BLASTP bit-score cutoff, Loose RGI matches have a bit-score less than the curated BLASTP bit-score cut-off.
Bit-score Cut-off (blastP): 470
