Respiratory diseases in cattle present the largest problem in current cattle management. Among them diseases bovine respiratory complex (BRDC) is one of the most important. BRDC is a multi-causal disease manifested in a heavy inflammation of respiratory tract and the lungs. This diseases is spread all over the world and causes great economic losses, especially in intensive cattle breeding. Many microorganisms, i.e. viruses and bacteria, may cause BRDC, but most often the diseases is induced by stress. In the paper BRDC etiopathogenesis is described from the aspect of virus and bacterial infection. It should be noted that special attention is given to bovine respiratory syncytial virus (BRSV) because, according to data in literature, this virus is now days considered the most frequent causative agent of BRDC. In Serbia BRSV has not been isolated, but some data point on the fact that it could play a role in bronchopneumonia of the cattle. The aim of the author is to inform the public, and to give a detailed description of BRSV and its possible role in the etiology of BRDC.
