A higher degree of diversity of <jats:italic>E.\u00a0faecalis<\/jats:italic> was observed in cluster 1 (C1, 28%) and cluster 2 (C2, 22%) from samples isolated from infected root canals. CPS type 2 was the dominant form observed in five clusters (C1\u2013C5), but there was no relationship between the origins of these isolates. In contrast, all isolates in cluster C5 were of root canal origin, and 50% were associated with a strong biofilm phenotype. Five unclustered strains were saliva isolates (&lt;60% similarity).
