Simulated microgravity conditions, independently of multiplicity of infection, does not influence the reproduction of adenovirus in cells which were clinorotated for 48 h after adsorption of virus. The incubation of infected cells before clinorotation under static conditions at a temperature of 4 °С for three days (the conditions for keeping of cells before the flight) does not change the number of infected cells relatively to control, but some changes of cell morphology are revealed, namely round off and aggregation of cells. The adenoviruses which were exposed in the medium keep infectivity under the conditions of clinorotation at 4 and 20–22 °С over prolonged periods (90 and 60 days, respectively). A model is elaborated for investigation of the influence of space flight factors on the interaction of the adenovirus and Epstein–Barr virus genomes at combined infection of limphoblastoid cells.
