Abstract
ADENOVIRUS-ASSOCIATED viruses (AAV) are small, DNA parvoviruses which are unable to multiply in cell culture unless cells are also infected with a helper adenovirus1. Furthermore, natural infection in man also requires co-infection with helper virus2. It has been shown that AAV multiplication is defective at some step(s) subsequent to adsorption of the virus and uncoating of the viral DNA3. In addition, there is evidence that both complete helpers (adenoviruses) and partial helpers (herpes viruses) provide one or more functions required for synthesis of AAV DNA and RNA3,4 and antigen5,6. Helper viruses contain a double stranded genome, whereas the AAV genome is single stranded. Also unlike any other animal viruses, AAV particles contain either a “plus” or “minus” strand of DNA7,8.
