[Phenomenon of temperate phage restriction and modification in a lysogenic culture of Streptomyces hygroscopicus].

Temperate phages were isolated from the lysogenic culture of Streptomyces hygroscopicus 0485 in the indicator cultures of Str. hygroscopicus 0477 and Str. levoris 1331. The phages were found to be identical in the morphology of particles and serological properties. The phenomenon of cross limitation, by the culture of Str. hygroscopicus 0477, of the phage growing on the culture of Str. levoris 1331, and vice versa, was established. At the same time, the phages were shown to be modified by the host cell.
