The anaerobic, gastrointestinal pathogen, Clostridium difficile, persists within the environment and spreads from host-to-host via its infectious form, the spore. To effectively study spore formation, the physical differentiation of vegetative cells from spores is required to determine the proportion of spores within a population of C. difficile. This protocol describes a method to accurately enumerate both viable vegetative cells and spores separately and subsequently calculate a sporulation frequency of a mixed C. difficile population from various in vitro growth conditions (Edwards et al., 2016b).
