[Effect of prolonged storage times on the infectivity of lyophilized arboviruses].
Lyophilized arboviruses of the following taxonomic groups: alfaviruses, flaviviruses, Bunyamwera supergroup viruses, as well as arenaviruses were used in the study. These viruses had been stored for a long time at --20 degree C. Determinations of the infectious titers in suckling mice showed that in a period of over 10 years (up to 21 years) no complete loss of infectivity occurred in any virus groups.
