title: [Changes in the dynamics of viral infectious diseases].
abstract: Modern methods of molecular biology are suitable to analyse evolutionary processes in the area of infectious diseases. Visible expression of this evolution is the emergence of "new" infectious agents, e.g., canine parvovirus, the agent of the porcine reproductive and respiratory syndrome and phocine distemper virus. In addition a gradual change of disease syndromes may be observed, e.g., classical and African swine fever and myxoma. These processes are based on genomic changes of the respective infectious agents, i.e., point mutations and recombinations. Especially RNA viruses are prone to genomic change, and the plasticity of their genomes enables them to adapt to varying selective pressures. Human activities in agriculture, global commerce and tourism may enhance and precipitate microbial evolution.
