A color-enhanced scanning electron micrograph of Trichomonas vaginalis (green) and vaginal tissue (pink). Sequencing the genome of T. vaginalis has given the researchers gory reading material on some of the pathogen's foul habits. The parasite latches onto vaginal tissue and forms tendril-like projections into it. The pathogen also secretes a series of proteins which destroy the vaginal epithelial cells, the cells that make up the vaginal tissue surface.
