Infection Characterizations of four Grass Carp Reovirus(GCRV)Strain
Abstract: Abstract:Some characterizations of four Grass Carp Reovirus(GCRV)strains were comparatively studied at the first time.It showed that the stored GCRV873,GCRVs75 and GCRv876 at minus 3012 for ten years still remained infectious to CIK cells,and the 3 virus titers could reach above 10 TCIDs0/ mI ,which was a little lower than the newly isolated GCRV99l strain s.After inoculation 3 4 genera— tions,their titers rised gradually,and the titer of GCRV873 could be up to the highest,which was al— most 6 4x10“TCIDso/mI with 0.05PFu/cellmultiplicity ofinfection(MOI)at 2812 .Theinfec— tive ability of the four strains at different temperatures(28℃ ,3l℃ 。34℃ ,37℃ and 41℃ )was also detected,which revealed that CPE appeared in CIK cells under above conditions,but titers depressed as the temperature rised In addition,4 GCRV—ds RNAs were also compared in a same electronic con— dition。
