摘要：

This study was undertaken to investigate the occurrence of several uncultivated phylotypes and newly named bacterial species in symptomatic endodontic infections. Samples taken from cases clinically diagnosed as acute periradicular abscesses or acute periradicular periodontitis were surveyed for the presence of 12 taxa by means of a 16S rRNA-gene-based nested or hemi-nested PCR assay. The most prevalent of the target taxa were Dialister invisus, Olsenella uli, Granulicatella adiacens, and Synergistes clones BA121 and E3_33. Findings revealed that novel phylotypes and newly named species can take part in the microbiota associated with symptomatic endodontic infections and a pathogenetic role is suspected.
