    Summary

    Ulcerative posthitis in bulls is linked to high-nutrition diets and Corynebacterium renale. This bacterial infection causes ammonia production, leading to penile lesions in cattle.

    Area of Science:

    • Veterinary Medicine
    • Bovine Health
    • Pathology

    Background:

    • Ulcerative posthitis is a significant concern in cattle populations.
    • Previous understanding of the etiology and contributing factors remains incomplete.

    Purpose of the Study:

    • To describe the incidence and characteristics of ulcerative posthitis in bulls in Uruguay.
    • To investigate potential etiological agents and risk factors associated with the condition.

    Main Methods:

    • Examination of 1096 bulls across 17 establishments in Uruguay.
    • Assessment of pasture type (improved vs. natural) and age as potential risk factors.
    • Histopathological analysis of preputial lesions and isolation of Corynebacterium renale.

    Main Results:

    • High incidence rates observed, particularly in bulls on improved pastures and those aged 18-36 months.
    • Histological findings included acanthosis, parakeratosis, hyperkeratosis, leukocytic invasion, and ulceration.
    • Corynebacterium renale was isolated from 59 of 204 prepuces examined.

    Conclusions:

    • The study postulates that ulcerative posthitis is primarily caused by ammonia production from urea hydrolysis by Corynebacterium renale.
    • High planes of nutrition, associated with improved pastures, appear to increase susceptibility.
