Single-Cell Enumeration of an Uncultivated TM7 Subgroup in the Human Subgingival Crevice
1 Oct 2003
Abstract excerpt
Specific oligonucleotide hybridization conditions were established for single-cell enumeration of uncultivated TM7 and IO25 bacteria by using clones expressing heterologous 16S rRNA. In situ analysis of human subgingival crevice specimens revealed that a greater proportion of samples from sites of chronic periodontitis than from healthy sites contained TM7 subgroup IO25. In addition, IO25 bacterial cells from...
