Abstract

Based on the molecular analysis of human subgingival plaque samples from 30 periodontitis patients a novel lineage of Archaea within the phylogenetic radiation of Thermoplasmatales was identified in 10% of cases. Co-occurrence of unique 16S rRNA gene and mcrA gene sequences suggests that this lineage corresponds to a hitherto unknown group of methanogens.
