Abstract: Johne's disease-paratuberculosis-affects domesticated and wild ruminants throughout the world. The first symptoms of the disease appear 6 months to 15 years after infection. The clinical stage of paratuberculosis usually occurs in older animals and is rare in those under 2 years of age. While performing analyses on a farm in the northeastern region of Poland a 2-year-old heifer that manifested symptoms of dyspepsia, proceeding with watery diarrhea, was observed. ELISA test (IDEXX) results demonstrated a positive serological reaction for paratuberculosis. Clinical examination, microbiological analysis of feces, autopsy, and histopathological examination confirmed the incidence of Johne's disease in the heifer.
