GRHPR and Liver abscess: A new putative virulence gene was identified in VPKP220 showing similarity to type III fimbriae cluster gene mrkD, along with the genes connected to the anaerobic utilization of allantoin as a nitrogen source found in VPKP284 (allD, allR, arcC, and glxR), which are most often present in isolates causing liver abscesses (30, –, 32).
