Abstract
To estimate the prevalence of bovine tuberculosis in the Alpine region, we studied the epidemiology of Mycobacterium caprae in wildlife during the 2009–2012 hunting seasons. Free-ranging red deer (Cervus elaphus) were a maintenance host in a hot-spot area, mainly located in Austria.

Ingestion of the M. bovis bacteria led to lymphatic spread from the primary infection, the gut, to mediastinal or tracheobronchial lymph nodes, which explained the lesions in the mesenteric lymph nodes [6]
M. bovis causing tuberculosis is proposed to be a lymphatic disease [6]; we propose the same for M. caprae
Summary
To estimate the prevalence of bovine tuberculosis in the Alpine region, we studied the epidemiology of Mycobacterium caprae in wildlife during the 2009–2012 hunting seasons. Author affiliations: Austrian Agency for Health and Food Safety, Moedling, Austria Prevalence estimates; the number was based on the red deer density of a region. Sample material included both medial retropharyngeal lymph nodes and tracheobronchial, mediastinal, and mesenteric lymph nodes and any other tissue with macroscopically visible lesions (Table 2).
