Abstract
ABSTRACT
Interactive classroom activities are an effective way to reinforce knowledge and promote student engagement. In this paper, we introduce the Pathogenesis Card Game (PCG), an innovative card game that engages students in a battle between microbial pathogens and the host immune system. Each student is given a set of cards that consist of either common host defenses or common pathogen evasion strategies. In pairs, students play a host defense card versus a pathogenesis card. Host defense cards include neutralize (antibody production), eat (phagocytosis), and destroy (degranulation). Pathogenesis cards present evasive strategies including mimic (molecular mimicry), escape (hemolysin production), hide (polysaccharide capsule), block (antioxidant defense), cut (protease secretion), and disguise (antigenic variation). Students develop a mastery of microbial pathogenesis through active gameplay by deliberating the outcome of each unique host-pathogen interaction. Furthermore, they learn the role of cells in the immune system and how pathogens can evade these immune defenses. PCG was piloted in a 300-level introductory microbiology course for 22 undergraduate students, comprising primarily biology and nursing majors. Both quantitative and qualitative student evaluations of the activity strongly suggest that PCG is an engaging, effective, and useful way to teach microbial pathogenesis. This activity provides a 60-minute lesson plan and corresponding materials that can be used to facilitate the introduction of pathogenesis to a typical undergraduate microbiology course. PCG offers instructors a framework to teach microbial pathogenesis and gives students the opportunity to construct their own knowledge about pathogen immune evasion in an engaging and interactive way.
