During the first 28 days, vaccinated calves shed both the vector strain and the intimin-expressing S. Calves challenged with intimin-deficient mutant bacteria do not develop diarrhea or attaching/ effacing lesions, nor are colonized to the same extent as animals infected with wild type or complemented mutant strains [20] . Fecal samples from all the calves were collected daily from day 0 to day 42 post-inoculation to determine the level of vaccine strain shedding. Immunization of cattle with a combination of purified intimin-531, EspA and Tir significantly reduces shedding of Escherichia coli O157:H7 following oral challenge ./cache/cord-346250-9kiekksx.txt ./txt/cord-346250-9kiekksx.txt
