Research Abstract

Factors involved in the adherence of Candida albicans and C. tropicalis was investigated using immobilized proteins. It was revealed that specific adherence and electrostatic interaction mainly contributed to C. albicans adherence and that hydrophobic interaction and specific adherence were involved in the adherence of C. tropicalis.
To clarify the relative contribution of these adherence forces to fungal adherence, three way analysis of variance was performed on the adherence of yeasts using surface-modified glass slides, and following results were obtained.
1) Electrostatic and lectin-like interaction were dominant in the adherence of C. albicans.
2) Adherence of C. tropicalis depends mainly on hydrophobic interaction.
3) Irreversible adherence was attributed to both electrostatic and specific factors, subsequently, hydrophobic interaction may stabilize the fungal adherence.
