| Accession | ARO:3000236 |
| CARD Short Name | vanA_cluster |
| Definition | This inducible cluster confers high resistance to both vancomycin and teicoplanin by allowing restructuring of peptidoglycan precursors to end in D-Ala-D-Lac. The vanA gene cluster can be located either on plasmids or on the chromosome. Gene orientation: vanRSHAXYZ. |
| AMR Gene Family | glycopeptide resistance gene cluster |
| Drug Class | glycopeptide antibiotic |

Prevalence of glycopeptide resistance gene cluster VanA among the sequenced genomes, plasmids, and whole-genome shotgun assemblies available at NCBI or IslandViewer for 414 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).
