✦ Synopsis
In this study, cell walls from Candida albicans were separated and chitin was isolated from these cell walls. A chitin soluble extract (CSE) prepared from the chitin inhibited in vitro adhesion of C. albicans to human epithelial vaginal cells (VEC), and blocked in vivo attachment to murine vaginal mucosa, thereby preventing candidal infection in these animals. These findings suggest that the CSE acts as an adhesin-like substance.
Fractionation of CSE yielded two fractions: FI and FII, of which only FI exhibited inhibitory activity. Chemical analysis of CSE and its two fractions revealed that CSE contains over 70% of proteins, most of which were found in the non-active fraction. In addition, 3% of amino-sugars were found in the FI active fraction. Lipids were also detected in the unfractionated CSE and in both fractions.
Experiments to further characterize the component(s) in the CSE inhibiting the attachment of C. albicans are in progress in our laboratory.
