Haemagglutination patterns of the different variants of Escherichia coli K88 antigen with porcine, bovine, guinea pig, chicken, ovine and equine erythrocytes.
Determination of the porcine adhesive phenotype was not achieved by haemagglutination (HA) of porcine erythrocytes, which in all cases were agglutinated by K88ab and K88ad, independent of the adhesive phenotype as determined by the brush border adhesion test. K88ac always gave negative HA results with porcine red cells. However, HA appeared to offer a method of differentiating between the K88 variants without monospecific antisera. K88ab agglutinated porcine, guinea pig and chicken erythrocytes; K88ac agglutinated only guinea pig red cells and K88ad produced haemagglutination with porcine and guinea pig erythrocytes.
