[14] [11] [13] Infected cattle may also have a higher frequency ...
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.
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 ...
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 ...

A wide variety of clinical signs have been described for HS in cattle and buffaloes. [2] The incubation periods for buffalo calves 4–10 months of age varies according to the route of infection. [20] The incubation period is 12–14 hours for subcutaneous infection, approximately 30 hours for oral infection, and 46–80 hours for natural exposure.
