Surface characteristics of Pseudomonas cepacia.
Two major surface characteristics of Pseudomonas cepacia were examined in this study: reactivity with lectins and hydrophobicity. The results indicated that the surfaces of P. cepacia strains are heterogeneous with regard to the distribution of lectin receptors. Only lima bean agglutinin was found to strongly agglutinate all strains. The strains were also heterogeneous with regard to hydrophobicity as determined by adhesion to hexadecane. The degree of hydrophobicity, however, was not significantly altered when selected strains were mixed with either fibronectin or bovine serum albumin. In addition, the strains exhibited no apparent affinities for buccal epithelial cells and gave no evidence for an ability to haemagglutinate human red cells.
