    Summary
    This summary is machine-generated.

    Indigenous bacteria in the canine urethra prevent pathogen colonization. Hormonal changes during estrus increase susceptibility to certain bacterial infections, impacting colonization dynamics.

    Area of Science:

    • Veterinary Microbiology
    • Urogenital Tract Infections

    Background:

    • Bacterial interference by commensals limits pathogen colonization.
    • The canine urethrovaginal area shares similarities with the vagina, suggesting hormonal influence.

    Purpose of the Study:

    • To determine the normal canine urethrovaginal flora.
    • To investigate the impact of estrus on bacterial colonization and persistence.

    Main Methods:

    • Serial culturing of the canine urethrovaginal flora.
    • Inoculation with specific bacterial species during different estrous cycle phases.

    Main Results:

    • Normal flora includes Staphylococcus epidermidis, Corynebacterium, and Acinetobacter-Haemophilus.
    • Estrus promotes overgrowth of beta-Streptococcus and Acinetobacter-Haemophilus.

  • Indigenous bacteria limit foreign species, while estrus enhances susceptibility to colonization.

    • Conclusions:

    • The canine urethrovaginal microbiome plays a role in preventing infections.
    • Hormonal fluctuations during estrus significantly alter the susceptibility to bacterial colonization.
