Segments range from about 0. The virus can enter the host cell via a receptor on the cell surface. The virus is partially uncoated by proteases in the endolysosome, where the capsid is partially digested to allow further cell entry. Translation takes place by leaky scanning, suppression of termination, and ribosomal skipping.
The virus exits the host cell by monopartite non-tubule guided viral movement, cell to cell movement, and existing in occlusion bodies after cell death and remaining infectious until finding another host. 2 or more virus genomes, each containing inactivating genome damage, can interact within an infected cell to form a viable virus genome. MR for three types of reovirus after exposure to ultraviolet irradiation. In their experiments, reovirus particles were exposed to doses of UV-light that would be lethal in single infections.
