This is an advanced microbiology course that will cover the mechanisms by which microbial pathogens cause infections in humans and/or animals. Microbial pathogens include bacteria, viruses, fungi, and parasites and together account for a significant percentage of acute and chronic human diseases. Emphasis will be placed on discussing how both microbes and their hosts have co-evolved molecular and cellular mechanism to evade and overcomes the offensive and defensive mechanisms of one another.
