[Bacteriophages from micrococci (author's transl)].

Using 14 indicator strains we investigated the possibilities of isolation of bacteriophages from micrococci (two strains of M. luteus, three strains of M. varians and one strain of M. roseus). Three phages were released after mitomycin C-induction, four phages after UV-rays-induction. These seven strains seem to be the first known bacteriophages, which were released from naturally lysogenic micrococci. Induction experiments with beta-propiolacton and dimethylsulfate as well as tests of spontaneous lysogeny produced only negative results.
