Abstract : Since the study of a few bacteriophage systems has significantly contributed to an understanding of virus-host relationships, the study of additional systems, differing from those already in existence, might be expected to add to the knowledge in this area. Since the Salmonella group of organisms constitute a group of significance to man being responsible for such diseases as the typhoid and paratyphoid fevers, enteric fever and Salmonellosis, and since a diversity of types of Salmonella phages has been described and since many new methods of investigation now exist not available to earlier workers, it seemed desirable to examine the systematics of the Salmonella phages. A group of phages isolated from lysogenic strains of S. potsdam was selected for study. As a result of the investigations, the Salmonella phage groupings originally suggested by Burnet have been revised. One of the newly defined groups, called group B, includes phages of a new morphology not previously described. Group B phages were found also to have a host range that included E. coli.
