We compared the pathogenicity of intimin-negative non-O157:H7 Shiga toxin (Stx)-producing Escherichia coli (STEC) O91:H21 and O104:H21 strains with the pathogenicity of intimin-positive O157:H7 and O157:H- strains in neonatal pigs. We also examined the role of Stx2d-activatable genes and the large haemolysin-encoding plasmid of O91:H21 strain B2F1 in the pathogenesis of STEC disease in pigs.
