One of Dr. Guiton's favorite topics in microbiology. We will enter the amazing, very diverse world of parasites (Protozoans, helminths, arthropods). We will learn about the history of parasitology (highlighting some of the pioneers), the biology of parasites, the disease they cause, the molecular mechanisms underlying their interactions with their hosts (entry, attachment, nutrient acquisition, replication, and immune evasion). We'll also touch on the epidemiology of parasitic infections, their public health impact, as well as prevention, diagnosis, and treatments of these infections. Concepts of microbial pathogenesis will be emphasized. Students will be able to improve on their writing skills as well as oral communication skills through small group projects. In class discussions of case studies and hands on activities will supplement the lecture.
