Microbial Source-Tracking and Detection Techniques
(Related terminology - "bacterial source tracking (BST)" and "molecular microbial technologies")
Links are provided below to general information on microbial source-tracking and detection techniques,
such as ribotyping (DNA fingerprinting), genetic enterovirus detection using PCR/rtPCR and IC/PCR, and pulse
field gel electrophoreses (PFGE).
