15 Escherichia coli strains of the serogroup O139, isolated from oedema disease of swine, were examined for their ability to interact with 125 I‐labelled fibronectin. All strains were positive, and all except one showed higher fibronectin binding than Staphylococcus aureus strain Cowan 1 cells (to which fibronectin bound in the order of 15% of total protein added). 7 E. coli strains isolated from diarrhoea in young piglets were also tested, and 3 were positive. 2 of these strains showed higher binding than S. aureus Cowan 1 cells. E. coli strains expressing either K99 or K88 antigen were poor binders, comparable to cells of S. aureus strain Wood 46. There was no correlation between cell surface hydrophobicity, as determined by chromatography on Octyl‐Sepharose, and the fibronectin‐binding property.
