title: [Biological interactions between viruses and their hosts. Particular case of ivy virus].
abstract: Viruses may be compared with parasites; in spite of the deep differences between these two concepts, both parasites and viruses limit the possibilities of their host. In the peculiar case of the Ivy, the specific virus seems to remain always very rare and by its wholly stimulating action, would rather play the role of a symbiote.
