Abstract

Summary.

Twenty-three strains of Escherichia coli with mannose-resistant and eluting (MRE) haemagglutinins with eight different patterns of substrate specificity were examined by a variety of electronmicroscope methods. In 12 strains, the presence of MRE haemagglutinins with broad-spectrum patterns 1, 3 and 4 was correlated with that of fimbriae. In 11 strains with MRE haemagglutinins with the less common patterns 6, 7 var., 8, 9 and 10, fimbriae were not found on bacteria in MRE+ cultures, indicating that the latter haemagglutinins are non-fimbrial.
