Abstract
A method is provided for the selection of diagnostic genetic markers fragments and useful in the identification of bacteria at the genus, species or serotype level. The method first involves the identification of a RAPD polymorphic DNA fragment common to a particular microbial group, the identification of the most conserved regions of that fragment, and the preparation of specific primers useful for detecting the presence of a marker within the fragment whereby that set of primers is then useful in the identification of all members of the chosen microbial group. Also provided is a specific diagnostic marker for Salmonella and primers directed thereto.
