    Insights

    Oral administration of polyvinylpyrrolidone (PVP) did not alter rat intestinal microflora. However, PVP solutions demonstrated a bactericidal and agglutinating effect, decreasing the toxicity of Escherichia coli and Proteus vulgaris.

    Area of Science:

    • Microbiology
    • Pharmacology

    Background:

    • Intestinal microflora plays a crucial role in host health.
    • Understanding the impact of orally administered substances on gut microbiota is essential.
    • Polyvinylpyrrolidone (PVP) is a synthetic polymer with various applications.

    Purpose of the Study:

    • To investigate the effects of oral polyvinylpyrrolidone (PVP) administration on the intestinal microflora of rats.
    • To evaluate the in vitro antimicrobial and toxicological effects of PVP solutions on specific bacterial species.

    Main Methods:

    • Oral administration of PVP to a rat model.
    • Analysis of intestinal microflora composition.
    • In vitro assessment of PVP solutions' effects on Escherichia coli and Proteus vulgaris, including toxicity, bactericidal activity, and agglutination.

    Main Results:

    • Oral administration of PVP showed no significant impact on the intestinal microflora of rats.
    • PVP solutions exhibited a notable decrease in the toxicity of Escherichia coli and Proteus vulgaris.
    • PVP solutions demonstrated both bactericidal and agglutinating properties against these bacteria.

    Conclusions:

    • Polyvinylpyrrolidone (PVP) does not disrupt the intestinal microflora when administered orally in rats.
    • PVP possesses direct antimicrobial and detoxifying properties against common enteric bacteria like Escherichia coli and Proteus vulgaris.
    • PVP may have potential therapeutic applications due to its antimicrobial and anti-toxic effects on specific bacterial pathogens.
