parasites (Ascaris lumbricoides, Necator americanus and Taenia saginata

This is a power point presentation that has to be 15 minutes. Not too much information on the slides but information on the side so that I am able to understand it. Also maybe some charts or graphs from peer reviewed papers. Stating whether we reject or fail to reject hypothesis based on the information. Ignore the previous slides that is just the beginning of the presentation and background information.
Brief information explaining pathogenesis for each parasite on separate slide then reflecting on hypothesis.
