Infektionsmedizinische Herausforderungen

Persistent structural changes in agriculture and the ensuring geographical concentration of animal production into few regions has resulted in a potentially high risk for the spread of infectious disease in cattle production. These ala the threat of the introduction of exotic diseases, notably foot and mouth disease (FMD), and the detection and control of endemic infections with a high morbidity late, such as bovine herpes virus 1 (BHV1) and bovine viral diarrhoea (BVD). The risk of introducing FMD is greater with increasing movement distances and mole intense international trade. At every stage of production, including the maintenance of herd hygiene, all efforts are needed to minimise the risk of introducing disease and effectively prevent a primary outbreak. Infections with BHV1 and BVD lead to substantial losses in cattle herds. Also, it is increasingly important in intel national and national trade for herds to be certified BHV1 free. In both cases, the prevention or eradication of mono-causal virus infections appear technically possible and viable economically
