Abstract
The pattern of the infectious process induced by the epidemic A/Leningrad/134/57 (H2N2) virus and its cold-adapted (CA) variants in CBA mice and Syrian hamsters was studied. The strains under study inoculated into the animals under a mild ether anesthesia differed by virulence, reproductive capacity in the nasopharynx, trachea and lungs, as well as by the isolation rate from extrarespiratory organs of both mice and hamsters. Upon intranasal inoculation of mice without anesthesia, the CA strains were found to be incapable of dissemination into the lower parts of the respiratory tract with distinguished these viruses from the original epidemic strain A/Leningrad/134/57 as well as from the mouse-adapted strain A/PR/8/34 (H1N1) used as control. The experimental results show that both models are suitable for laboratory evaluation of the attenuation degree of human influenza viruses.
