title: Effect of various sodium taurocholate preparations on the recovery of Clostridium difficile spores.
abstract: The effect of four sodium taurocholate preparations, which are easily available in Japan, on recovery of Clostridium difficile spores was examined. All preparations, except for one, enabled the recovery of nearly all spores counted microscopically. Moreover, by using 69 toxigenic and 34 nontoxigenic C. difficile strains, the relationship between the recovery of spores in the medium with sodium taurocholate and toxigenicity of C. difficile was analyzed. It was noted that the number of strains with recovery rate of more than 70% was greater in toxigenic strains than in nontoxigenic strains, suggesting a more abundant recovery of toxigenic C. difficile strains in the presence of sodium taurocholate.
