When S. anatum (ε15) was infected with temperate phage ε34 or even with its virulent mutants, O antigen 34 appeared on the infected cells within 30 minutes. It indicates that the formation of the new character, antigen 34, was carried out even in cells which are destined to lysis. The mutation from temperate to virulent proved not to be related to the mutation in converting abilities.
