We compared the amounts of methanogenic archaea with ten of the most important periodontal pathogens in 125 clinical samples. Correlation analysis suggests that the support of the periodontitis-associated bacterial consortium by methanogenic archaea may be driven through direct or indirect interactions with Prevotella intermedia.
