1. A method for preventing an F18 pathogenic E. coli intestinal infection in an animal, comprising intestinal delivery to the animal of an effective amount of a live E. coli strain deposited at the International Depositary Authority of Canada (IDAC) on Jun. 20, 2013 and attributed accession number 200613-01.
2. The method of claim 1 , wherein said intestinal delivery is obtained by oral administration of the live E. coli strain.
