Expression cassettes and methods for delivery of animal vaccines

摘要: The present invention provides an expression cassette for expressing vaccine antigens in a plant cell. includes DNA sequence which encodes at least one antigen is operably linked to transcriptional and translational control regions functional the of are useful protection animal against mucosal diseases such as Transmissible Gastroenteritis Virus (TGEV) rotavirus. also transgenic seed has been stably transformed express included invention. cells may be from monocot or dicot plants include, example, corn, soybeans, sunflower, canola alfalfa. seeds used feed composition animals. Alternatively, provide immunogenic protecting animals after oral administration.
