The diagnosis of tuberculosis in animals is a complex process that is crucial for determining the effectiveness of measures to combat this disease. Currently, tuberculosis in animals is not reported in Ukraine; however, each year, 40–60 livestock farms need to assess the epizootic situation regarding this disease due to nonspecific allergic reactions to tuberculin in cows during routine diagnostic tests. This article presents generalized and systematized findings from long-term studies (2000–2024) on comprehensive anti-tuberculosis measures for cattle in various types of Ukrainian farms. This complex included epizootic, clinical, allergic, pathological, bacteriological, and statistical research methods. Based on the experiences gained from scientific and practical work, key criteria (or markers) for establishing a tuberculosis diagnosis in cattle and differentiating this disease within herds have been identified. In addition, the presented work contains original photographs that demonstrate pathological macroscopic changes characteristic of the course of the infectious tuberculosis process in animals, as well as the cultural and morphological features of mycobacterial cultures isolated from biological material. The main indicators (markers) characterizing the course of epizootic and infectious tuberculosis process in cattle herds and used to diagnose this disease were identified: clinical signs, the manifestation of allergy, pathological signs, source of the infectious agent, environmental conditions, biochemical tests, type of laboratory animals.
