Genotypic identification of bacteria

WebThe traditional identification of bacteria on the basis of phenotypic characteristics is generally not as accurate as identification based on genotypic methods. For many years, sequencing of the 16S ribosomal RNA (rRNA) gene has served as an important tool for determining phylogenetic relationships between bacteria. WebDNA sequencing of the gene for the 16S ribosomal subunit, a component of the cellular protein synthesis machine, is used to identify bacteria that may not be identified by phenotypic methods described earlier. Sequencing ribosomal or other genes may also be used for identification of fungi, mycobacteria, and viruses.
