A targeted molecular method that amplifies and determines nucleotide sequences from the bacterial 16S ribosomal RNA (rRNA) gene (conserved and variable regions) to infer the taxonomic composition and relative abundance of bacteria in a sample; it is a survey tool for bacterial profiling, with limited species- and strain-level resolution and no direct information on viability or non‑bacterial organ
