In the ecosystem, the virus is a very active member. The distribution of viruses in nature and its widespread, infectious organisms in the five major sectors - animal, plant kingdom, fungal community, protozoa and prokaryotes. That the virus can infect almost all organisms. From vertebrates to fish, amphibians, reptiles, avian and mammalian classes, invertebrate coelenterates, molluscs and arthropod insects, arachnids and crustaceans to protozoa; from the seed plant quilts Plants and gymnosperms, ferns to eukaryotic algae; various fungi from microorganisms such as algae, ascomycetes, basidiomycetes to semi-congenital bacteria; from bacteria, actinomycetes and cyanobacteria to rickettsia Mycoplasma and mycoplasma. Even the virus
