Abstract | Hydrophobic interactions between bacterial cell surfaces and colonisable substrates have been implicated in the mechanisms of bacterial adherence. However, current methods of assessing bacterial hydrophobicity as a function of adherence to liquid hydrocarbons (especially hexadecane) do not always produce accurate or reproducible results. Therefore, the present technique was developed using xylene. The hydrophobic surface properties of fresh and type strains of Bacteroides gingivalis, Bacteroides intermedius, Capnocytophaga spp., Streptococcus salivarius and Streptococcus sanguis suspended either in saliva ions buffer (SIB) or in saliva diluted in SIB were measured. In SIB the test strains were predominantly hydrophobic. The addition of saliva caused a significant reduction (P<0.05) in hydrophobicity compared to SIB alone, with 80% of the strains tested. Since oral bacteria will be suspended in saliva in vivo, it is concluded that bacteria in the oral cavity may be less hydrophobic than previous studies have suggested. |
