A Review on Bovine Tuberculosis

Abstract

Zoonotic tuberculosis caused by Mycobacterium bovis is common in most developing countries like Nigeria. Bovine tuberculosis is a chronic infectious zoonotic disease of domestic animals and humans. It is characterized by formation of granulomas in tissue especially the lungs, lymph nodes, liver, intestines and the kidneys. In Nigeria bovine tuberculosis is endemic and mostly transmitted to humans through ingestion of unpasteurized contaminated milk and contact with infected animals. It is important to pasteurize milk before human consumption. The Fulani herdsmen that are predominantly rural dwellers should also be educated on the need to boil milk before consumption since they lack infrastructures for pasteurization. Tuberculosis causes great economic losses on farmers and is of public health importance. The meat inspection system should also be strengthened and designed to prevent the consumption of contaminated products. This review advocates that developed countries should provide educational and technical assistance to developing countries like Nigeria to promote the control of tuberculosis. In Africa heads of government, agricultural and health sector should create the infrastructures necessary for this to be achieved. Personnel at all levels of the control program should be properly trained.

Evaluation of fetal bovine serum as a source of enrichment in synthetic culture medium for the isolation of Mycobacterium bovis

“…Possui marcada importância econômica decorrente das perdas na produtividade, morbidade, mortalidade, condenação de carcaças em abatedouros, embargos ao comércio de produtos no mercado internacional, custos com programa de controle e erradicação, ameaça à saúde pública e de espécies protegidas em risco de extinção (Borham et al, 2022;Carneiro et al, 2019;Dib, 2023;Hoffmann et al, 2022;Krajewska-Wedzina et al, 2018). É uma doença infecciosa crônica caracterizada pela formação de granulomas nodulares conhecidos como tubérculos, que podem afetar qualquer órgão ou tecido, embora acometam com mais frequência linfonodos (principalmente de cabeça e tórax), pulmões, intestinos, fígado, baço, pleura e peritônio (Admassu et al, 2015;Nascimento & Nardi Júnior, 2022;Neves et al, 2017;OIE, 2018;Teppawar et al, 2018).…”
