All phages studied are tailed, belong to six morphological groups, and are classified by morphological and serological properties and by physico-chemical parameters of the virion and its nucleic acid. Four species of Agrobacterium and 12 species of Rhizobium phages are described, and their relationship with enterobacteria phages discussed. They include 68 viruses, whereas 60 poorly known phages have not been classified.
