The enzootic balanoposthitis

Abstract

In 2021, the Podplud bull was treated at the Pszczyna-Jankowice European Bison Breeding Center for necrotic balanoposthitis (NZN). Treatment reduced clinical symptoms. Another case of NZN was noted in 2022 in the bull Ponse, which had purulent necrotic lesions and sepsis caused by the bacterium Trueperella pyogenes during post-mortem treatment. Further observations in multiple bulls confirmed the disease.Twenty-three bulls were immobilized, a clinical examination was performed, swabs were collected for bacteriologic examination. Based on the results of these examinations, seven animals were eliminated. Post-mortem examinations bring anatomical-pathological changes to the development of severity and a variable proportion of pathogenic bacteria.
