Experimental infections with four different rabbit enteropathogenic Escherichia coli (EPEC) biotypes were carried out in EPEC free rabbits, and intestinal colonisation was assessed by measuring semi-quantitatively the rectal colonisation. When the animals were infected for the first time shortly after weaning, the excretion followed an approximately identical course with all four EPEC: at 3-9 d post-infection all rabbits excreted the infecting EPEC strain in high quantities, and continued to do so for 1-2 wks. Rabbits that had survived such a colonisation with one EPEC, were protected against colonisation with strains belonging to other EPEC groups.Keywords: E. coli; Rabbit EPEC; Intestinal colonisation; Cross-protection.
