[Bacillus thuringiensis bacteriophage interference]

R R Azizbekian

    Genetika
    |January 1, 1981
    PubMed
    Summary

    Temperate bacteriophage Tm2 interferes with virulent bacteriophage Tg4 by altering Bacillus thuringiensis host physiology, not the viral genome. This interference impacts phage development and progeny yields, depending on the order of phage addition during mixed infections.

    Area of Science:

    • Bacteriophage biology
    • Microbial genetics
    • Bacterial-phage interactions

    Context:

    • Bacillus thuringiensis strains lysogenic for temperate bacteriophage Tm2 exhibit resistance to virulent bacteriophage Tg4.
    • This interference mechanism involves host physiology alteration rather than direct action on the viral genome.

    Purpose:

    • To investigate the interference mechanism between temperate bacteriophage Tm2 and virulent bacteriophage Tg4 in Bacillus thuringiensis.
    • To determine the effect of phage addition order on progeny yields during mixed infections.

    Summary:

    • Temperate phage Tm2 lysogeny in Bacillus thuringiensis inhibits virulent phage Tg4 development by prolonging Tg4's latent period and reducing progeny yields.
    • Phage dominance in mixed infections is order-dependent; pre-infection with one phage (Tm2 or Tg4) for 5 minutes significantly impacts the yield of the subsequently added phage.
    • Simultaneous addition of both phages results in reduced yields for both Tm2 and Tg4.

    Impact:

    • Elucidates a novel phage-mediated interference mechanism in bacteria.
    • Provides insights into the complex dynamics of phage-host interactions and co-infections.
    • Highlights the importance of temporal factors in determining phage-bacterial population dynamics.
