Abstract

From stocks of adenovirus and poliovirus prepared in primary rhesus macaque kidney cells and dating from 1956 to 1961, the time when SV40 contaminated some poliovirus vaccine lots, we have recovered ten isolates of SV40. Of these ten isolates, based on the C-terminal region of T antigen, five novel strains of SV40 have been identified. Additionally, three pairs of isolates were found to be the same strain: one pair was strain 777, one pair was strain 776 archetype, and the third pair represented a novel strain. All strains had identical protein sequences for VP2 and VP3. There were two variants of agnoprotein and the small t antigen and three variants of VP1. These results, and those of others, suggest that a limited number of SV40 strains might exist in rhesus macaques in the United States, and thus determining the origin of the SV40 sequences detected in human tumors might be difficult.
