SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--A novel antibacterial protein targeted against E. coli O157:H7 may offer a way to prevent or treat serious food-borne bacterial infections, as demonstrated in a study published in the December issue of Antimicrobial Agents and Chemotherapy. Results in an animal model of E. coli infection showed that the orally administered protein, developed by AvidBiotics, Inc., could prevent or treat E. coli O157:H7-induced diarrhea and intestinal inflammation when administered either on a preventative basis or after the onset of diarrhea. Moreover, animals treated with the protein also carried and shed fewer of the E. coli O157:H7 bacteria in their feces.
