As with bacterial classification, identification of bacteria is increasingly using molecular methods. Diagnostics using such DNA-based tools, such as polymerase chain reaction, are increasingly popular due to their specificity and speed, compared to culture-based methods.These methods also allow the detection and identification of "viable but nonculturable" cells that are metabolically active but non-dividing.
