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).
