  • Method of rapidly generating double-stranded RNA and methods of use thereof
    Publication number: 20020182223
    Abstract: The present invention provides eukaryotic double-stranded RNA (dsRNA) expression vectors containing two promoters directed head-to-head with a designated intervening sequence of interest that is effective in eukaryotic cells containing the dsRNA expression vector, and a vaccine using an attenuated eukaryotic pathogenic cell. The present invention also provides methods of vaccinating against colonization or infection of a eukaryotic pathogen. The present invention further provides methods of generating double-stranded RNA (dsRNA) and screening designated nucleic acids capable of inhibiting expression of an essential eukaryotic gene.
