Abstract
We have taken up the study of phage genetics, chiefly in connection with the problem whether the recombination phenomenon already demonstrated in the phages of T series can also be observed in other bacterial viruses.
We succeeded in finding evidence of genetic recombination for some pairs of characters in phages from S. gallinarum (Akita strain) and S. sendai (S. 71 strain).
The genetic characters chosen in this crossing experiments were plaque morphology, host-range and a peculiar lytic action of some viral strains against a phage resistant bacterium.
The recombination interpretation was confirmed by the results by crossing the respective recombinants.
It is also believed that among the genetic facts found in the crossing experiments, there are some specific data which are different from those reported for the phage of the T series. The authors believe that the analysis of these discrepancies will further widen our knowledge of phage genetics.
