title: Isolation of Escherichia coli O157 from pigs with colibacillosis in Canada and the United States.
abstract: Cultures of Escherichia coli isolated from colibacillosis in pigs in Canada and the U.S.A. and previously identified as unclassified E. coli OX36 were found to belong to a new E. coli O group 157. Strains of E. coli V145, GIRI, C308 and V17 which had a weak relationship to E. coli O116 also were found to belong to O157. The increased incidence of E. coli O157 in colibacillosis of swine stresses the inclusion of this O group among those enteropathogenic for swine.
