Molecular techniques: An overview of methods for the detection of bacteria

Several DNA molecular markers are now available for use in surveillance and investigation of food-borne outbreaks that were previously difficult to detect. The results from several sources of literature indicate substantially different degrees of sensitivities between conventional detection methods and molecular-based methods. The new technology is noted for increased sensitivity over the traditional culture methods which they complement.   Key words: molecular techniques, fingerprinting, microorganism.
