However, in areas of the developing world where pasteurisation is not routine, M. bovis is a relatively common cause of human tuberculosis. [5] Bovine tuberculosis is a chronic infectious disease which affects a broad range of mammalian hosts, including humans, cattle, deer, llamas, pigs, domestic cats, wild carnivores (foxes, coyotes) and ...
Diagnosing active tuberculosis based only on signs and symptoms is difficult, [99] as is diagnosing the disease in those who have a weakened immune system. [100] A diagnosis of TB should, however, be considered in those with signs of lung disease or constitutional symptoms lasting longer than two weeks. [ 100 ]
Mycobacterium tuberculosis is the most common cause of both pulmonary tuberculosis and tuberculous lymphadenitis. [1] [6] Historically, transmission of Mycobacterium bovis from dairy consumption was another frequent cause of tuberculous lymphadenitis, but incidence has drastically decreased in developed countries since the advent of pasteurization and other efforts to prevent bovine ...
Depending on the sort of patient population surveyed, as few as 20%, or as many as 75% of pulmonary tuberculosis cases may be without symptoms. [2] Tuberculosis should be suspected in adults when a pneumonia-like illness has persisted longer than three weeks, or when a respiratory illness in an otherwise healthy individual does not respond to ...
In cattle, the main signs of paratuberculosis are diarrhea and wasting. Most cases are seen in 2- to 6-year-old animals. The initial signs can be subtle, and may be limited to weight loss, decreased milk production, or roughening of the hair coat. The diarrhea is usually thick, without blood, mucus, or epithelial debris, and may be intermittent.

Tuberculosis verrucosa cutis is a rash of small, red papules and nodules in the skin that may appear two to four weeks after inoculation by Mycobacterium tuberculosis in a previously infected and immunocompetent individual. [citation needed]
Contagious bovine pleuropneumonia (CBPP – also known as lung plague), is a contagious bacterial disease that afflicts the lungs of cattle, buffalo, zebu, and yaks. It is caused by the bacterium Mycoplasma mycoides, and the symptoms are pneumonia and inflammation of the lung membranes. [1] The incubation period is 20 to 123 days.
