Haemagglutinating and adhesive properties associated with the K99 antigen of bovine strains of Escherichia coli.


The K99 antigen common to some bovine strains of Escherichia coli caused mannose-resistant haemagglutination of sheep erythrocytes and was shown to be responsible for the attachment of K99-positive bacteria to calf brush-border preparations because (i) strains grown at 18 degrees C did not produce K99 antigen, cause haemagglutination, or attach to brush… (More)
