title: [Pathogenesis of classical swine fever--similarities to viral haemorrhagic fevers: a review].
abstract: In spite of differences in etiology, viral haemorrhagic diseases share similarities in their pathogenesis. Characteristic for these diseases are thrombocytopenia, petechia and increased vascular leakage. Most lesions can be attributed to cytokine-mediated interactions triggered by infected and activated monocytes and macrophages, rather than by virus-induced direct cell damage. Causative agents of viral hemorrhagic diseases are enveloped RNA viruses. In most cases, they are transmitted to humans from their animal hosts by rodents or arthropod vectors (Arboviruses). Due to the clinical picture, the acute lethal form of classical swine fever (CSF) is also considered as a viral haemorrhagic disease. CSF is caused by an RNA virus in the family Flaviviridae, and members of the Suidae family are the only ones clinically affected. It is a highly contagious, therefore notifiable disease. In contrast to other viral hamorrhagic diseases, it is mainly transmitted oro-nasally by contact with infected pigs, or by contaminated items (semen, swill feed, clothing). The present survey summarizes analogies between classical representatives of viral haemorrhagic fevers, and recapitulates current knowledge concerning the pathogenesis of classical swine fever.
