| Abstract | ||||
| Bovine tuberculosis (BTB) is one of the most recognized endemic zoonotic diseases in the world, including Egypt. Mycobacterium bovis belongs to the strain of Mycobacterium TB complex, which is the main cause of bovine tuberculosis, which spreads via inhalation of infected droplets or consumption of infected food and water. Bovine tuberculosis causes severe economic loss, which has major implications on animal health, ranging from decreased milk output, weight losses, infertility, meat condemnation or even mortalities. Antemortem and postmortem examinations are used for the diagnosis of bovine tuberculosis. Antemortem procedures rely on either cellular or humoral immunological responses, whereas postmortem diagnosis is based on proper visual inspection and palpation. The tubercles are mainly found in lymph nodes, notably those in the bronchial, retropharyngeal, and mediastinal regions, with some exhibiting cheesy material when cut during meat inspection processes on animal carcasses at slaughterhouses. However, the bacteria can also spread throughout the blood, cause a systemic infection, and damage other organs. The histopathological examination is distinguished by the granuloma formation, including central necrosis, chronic inflammatory cell aggregation, mineralization, and peripheral fibrosis. Other diagnostic tests, such as bacterial isolation and PCR, are necessary to establish a final diagnosis. Vaccination, hygienic measurements and proper diagnosis are critical for preventing and controlling TB in humans and animals. | ||||
