C.  Secreted glucosidases of Trichomonas vaginalis

Human vaginal epithelial cells contain substantial quantities of glycogen.  Several studies have shown that these glycogen stores are depleted in women who are infected with T. vaginalis.  We have established that T. vaginalis grows equally well in growth media containing either glycogen or glucose as a carbon source.  Furthermore, we can detect secreted glucosidase activities in conditioned growth medium.  Preliminary characterization indicates that at least an α-amylase is secreted.  Current work is direct toward the further purification and characterization of the secreted glucosidases.  We hope to identify the enzymes required by T. vaginalis for utilization of exogenous glycogen, ultimately perhaps leading to the identification of novel therapies for trichomoniasis.
