Bacteriocin-like activity within the genus Actinomyces

J W Turner, H V Jordan

    Journal of Dental Research
    |June 1, 1981
    PubMed
    Summary

    Actinomyces strains showed low antagonism, but Streptococcus mutans strongly inhibited Actinomyces viscosus strains. This suggests S. mutans bacteriocins could differentiate A. viscosus strains.

    Area of Science:

    • Microbiology
    • Bacteriology
    • Oral Microbiology

    Background:

    • Actinomyces species are common in the human oral cavity.
    • Understanding inter-bacterial interactions is crucial for oral health.
    • Bacteriocin-like substances mediate microbial antagonism.

    Purpose of the Study:

    • To investigate bacteriocin-like antagonism among Actinomyces strains.
    • To assess the susceptibility of Actinomyces viscosus to inhibition by Streptococcus mutans.
    • To characterize the nature of inhibitory substances produced by S. mutans.

    Main Methods:

    • Testing various Actinomyces strains for bacteriocin production.
    • Evaluating zones of inhibition to quantify antagonism.
    • Assessing the heat stability, dialyzability, and enzyme sensitivity of inhibitors.
    • Determining A. viscosus strain differentiation based on S. mutans sensitivity patterns.

    Main Results:

    • Inter-strain antagonism among Actinomyces was infrequent and produced small inhibition zones.
    • Actinomyces viscosus strains were highly susceptible to inhibition by Streptococcus mutans.
    • Inhibition zones caused by S. mutans were large and well-defined.
    • S. mutans inhibitory substances were heat-stable, nondialyzable, and sensitive to proteases.
    • Distinct sensitivity profiles of A. viscosus strains to S. mutans inhibitors were observed.

    Conclusions:

    • Streptococcus mutans exhibits significant bacteriocin-like inhibitory activity against Actinomyces viscosus.
    • The observed inhibition patterns suggest potential for differentiating A. viscosus strains using S. mutans.
    • Bacteriocin production plays a role in the complex microbial ecology of the oral environment.
