Intestinal colonization of monoxenic mice by Clostridium difficile strains. Quantitation of viable vegetative cells (luminal bacteria, LB and tissue-associated bacteria, TAB) in the different parts of the intestine (jejunum, ileum, cecum, and colon). The data represent the average of three independent assays. No statistical analysis was performed because the number of mice tested was limited to three per strain.
