Abstract

Aeromonas sobria hemolysin is important in the pathogenesis of diarrhoea caused by this enteropathogenic bacterium. By immunoprecipitation analysis using hemolysin and anti-hemolysin antibody, a 66 kDa protein (p66) was identified as a receptor for A. sobria hemolysin on Intestine 407 cells. Treatment of p66 with N-glycosidase F reduced the apparent sized of p66 to 60 kDa on SDS-polyacrylamide gels. p66, released from Intestine 407 cells following incubation with phosphatidylinositol-specific phospholipase C (PI-PLC) treatment, bound A. sobria hemolysin. Thus treatment of Intestine 407 cells with PI-PLC resulted in the remarkable decrease of the sensitivity to A. sobria hemolysin. These results are consistent with the hypothesis that p66, the binding protein for A. sobria hemolysin, is a glycosylphosphatidylinositol-anchored glycoprotein expressed on the surface of Intestine 407 cells and probably plays a role as a receptor for A. sobria hemolysin on the intestinal cells.
