    Abstract: Provided herein are methods and systems for absolute quantification of a target 16S rRNA and/or of a target prokaryotic taxon, based on amplifying and sequencing a same 16S rRNA recognition segment in which target 16S rRNA conserved regions flank 16S rRNA variable regions, conserved and variable among a plurality of sample 16S rRNAs and/or of a sample prokaryotic taxon of higher taxonomic rank with respect to the target taxon. In the methods and systems, absolute abundance of the a plurality of sample 16S rRNAs and/or of the sample prokaryotic taxon detected by the amplifying, is multiplied by the relative abundance of the target 16S rRNA and/or of a target prokaryotic taxon detected by the sequencing to provide the absolute quantification in accordance with method and systems of the disclosure.
