Adeno-associated viruses inhibit SV40 DNA amplification and replication of herpes simplex virus in SV40-transformed hamster cells.
Coinfection with HSV-1 and any of the three defective parvoviruses AAV-2, AAV-3, or AAV-5 reduces the HSV-1-induced amplification of SV40 DNA in the SV40-transformed hamster cell lines CO631 and Elona. Moreover, all three viruses significantly decrease HSV-1 replication. The effects are measurable to the same extent in both cell lines and are dependent on the quantity of AAV DNA molecules rather than on infectious AAV particles. It seems unlikely that the inhibitions are due to simple competition but result from complex interactions that involve the terminal sequences of AAV DNA.
