We have investigated the production of verotoxin (VT) in 55 enteropathogenic and 48 non‐enteropathogenic Escherichia coli strains of porcine origin, belonging to 48 serotypes. VT cytotoxin was only produced by seven out of the eight enteropathogenic strains with serotypes O138:K81, O139:K82, O141:K85ab and O141:K85ac. Five haemolytic non‐enteropathogenic E. coli , four with serotypes O75:K‐, O75:K95 and O2:K2, and one not typable, synthesized a new thermolabile product not related with enterotoxin (LT) or VT, and which induced the formation of multinucleate cells in Vero monolayers.
