Viruses have_been found in all cellular forms of life, from bacteria to chordates. Pathogenic human and animal_viruses are causative agents of serious diseases such_as AIDS encephalitides, hepatitides, influenza etc. Plant_viruses are responsible_for many major agricultural problems. Therefore, studying various viruses and their interaction with hosts is a prerequisite for finding remedies against viral diseases and understanding principles of the organization of life.
