Abstract

Capillary-based PCR ribotyping was used to quantify the presence/absence and relative abundance of 98 Clostridium difficile ribotypes from clinical cases of disease at health care institutions in six states of the United States. Regionally important ribotypes were identified, and institutions in close proximity did not necessarily share more ribotype diversity than institutions that were farther apart.

Ribotype-based C. difficile population diversity. An unweighted-pair group method using average linkages (UPGMA) dendrogram displays the similarity between six U.S. health care institutions based on the presence/absence and relative abundance of all ribotypes observed in this study (Morisita-Horn index). Pie charts display the percentages of two main ribotypes (027 and 014-020) and all remaining (“other”) ribotypes for clusters A and B.
