Background: Trichomonas vaginalis is a protozoan parasite that occurs in the urogenital-vaginal tract and is the primary causative agent of trichomoniasis, a common sexually transmitted disease in humans. The aggregation of this protozoan tends to destroy epithelial cells and induce pathogenesis. Principal Findings: This study cultured T. vaginalis and human cervical epithelial cells (Z172) under the same conditions in the experiments. Following co-culturing for ten hours, the protozoans became attached to Z172, such that the cells presented a round shape and underwent shrinkage. Time-lapse recording and flow cytometry on interacted Z172 revealed that 70% had been disrupted, 18% presented a necrosis-like morphology and 8% showed signs of apoptosis. Gene expression profiling revealed in the seven inflammatory Z172 genes as well as in T. vaginalis genes that code for adhesion proteins 65 and 65-1. Significance: These results suggest that cytopathogenic effects progress while Z172 is in contact with T. vaginalis, and the resulting morphological changes can be categorized as disruption.
