Biological, Serological and Biochemical Investigations of Three Closely Related Temperate Bacteriophages Specific for Pseudomonas pseudoflava

Summary A close relationship between three temperate phages (gd, ge and gf), specific for three strains of the newly described species Pseudomonas pseudoflava was revealed by an identical pattern of structural proteins, by serological cross-reactions and by the finding of cross-immunity and cross-resistance. In addition attachment of the phages to the pili of their hosts and the presence of a restriction and modification mechanism was indicated.
