Abstract:
Erysipelothrix rhusiopathiae is the causative agent of animal erysipelas and human erysipeloid. E. rhusiopathiae HP0728 and HP1472 have been reported to be down regulated in low-virulence or avirulent strains, but their pathogenic roles are not known. In this study, it was found that E. rhusiopathiae HP0728 and HP1472 were displayed on the surface of E. rhusiopathiae. Moreover, recombinant HP1472 could adhere to pig vascular endothelial cells. Recombinant HP0728 could bind host plasminogen but could not bind fibronectin. In conclusion, our work suggested that HP0728 and HP1472 are virulence factors of E. rhusiopathiae.
