title: [Hemagglutinating activity of enterotoxic strains of E. coli isolated from calves].
abstract: The manose-resistant hemagglutination activity of 272 E. coli strains isolated from calves sick or dead of colibacteriosis, 43 of which were enteropathogenic, was assessed. Strain enteropathogeneity was determined after the method of Smith and Halls (1967). It was established that 38 (88.3%) of the 43 enteropathogenic strains cause full or partial hemagglutination of horse or pig erythrocytes. Manose-resistant hemagglutination was not observed in the non-enteropathogenic E. coli strains. Manose-resistant hemagglutination of enterotoxic E. coli strains is in relation with their enteropathogeneity.
