Molecular survey of the Salmonella phage typing system of Anderson.
Typing phages for Salmonella and the prophages of their typical propagation strains were analyzed at the DNA level. Most of them belong to the P22 branch of the lambdoid phages. Acquisition of new plating properties of the typing phages by propagation in particular strains can be due to different host specific modifications of the DNA or to recombination events with residing prophages which are reflected by changes in the respective DNA restriction patterns. It is concluded that the actually available set of typing phages is a historically unique combination of strains.
