Failure of adherence to buccal cells and surface hydrophobicity as virulence markers in Neisseria meningitidis.
Surface hydrophobicity and adherence to buccal epithelial cells were studied in 33 carrier and 34 invasive Neisseria meningitidis strains. It was found that hydrophobicity is statistically similar in both groups (P = 0.0507) although it could be considered that carrier strains are slightly more hydrophobic than invasive ones. Adherence was similar in both groups although more homogeneous in the carrier strains. No correlation could be demonstrated between these two properties nor can they be considered relevant as markers of the carrier or invasive status of this bacterium, indicating that at least in N. meningitidis they are not good properties to discriminate virulent strains.
