From: Epidemic ribotypes of Clostridium (now Clostridioides) difficile are likely to be more virulent than non-epidemic ribotypes in animal models

In vivo fecal-associated CFU counts were not different between isolates. For each isolate, groups (n = 20) were housed 5 to a cage and inoculated with approximately 1 × 106 C. difficile spores. Fecal pellets were then collected, weighed, and processed to measure CFU counts throughout the study. Mean fecal counts were not significantly different between the non-epidemic and epidemic ribotypes, and CFU counts peaked 3 days after infection which declined until the end of the study. These data represent the average of four independent groups, and error bars indicate the standard errors of the means
