This was concurrently confirmed for SAAN by Yebra and colleagues18 who highlighted vWbp as an important virulence factor, which is encoded on one of only two MGEs in the accessory genome of SAAN strain MVF7, the SAAN pathogenicity island SaaPIMVF7, and hypothesized this particular vwb variant to be highly relevant for the formation of classical abscesses in MD18. The gene discussed is HSPA9; the disease is abscess.
