The present invention provides a detection gene chip for diagnosing serveral kinds of hepatitis and new primer with high detection rate for using the gene chip in various subtype amplification. The gene chip includes detection quality controlling system and disease diagnosing system. The chip can be used to detect the virus ites of hepatitis B and hepatitis C and detect hepatitis D, hepatitis E, hepatitis G and TTV simultaneously. It has short detection period, high diagnosis accuracy and low diagnosis cost and may be used in epidemiological investigation and blood detection for identifying hepatitis gene type.

The invention discloses a canine distemper virus CDV-3 strain infectious cDNA cloning and constructing method and application thereof. A canine distemper virus CDV-3 strain is used as a template, theoverall length of the CDV-3 is divided into 5 fragments, and RT-PCR amplification is performed. Through enzyme-cutting splicing, the 5 fragments are sequentially inserted into a eukaryotic vector, besides, a hammerhead ribozyme sequence and a hepatitis D ribozyme sequence are respectively added to an F1 head end and an F5 tail end, and canine distemper virus CDV-3 strain infectious cDNA clone is obtained; then three auxiliary plasmids expressing CDV-3N, P and L proteins are constructed; the canine distemper virus CDV-3 infectious cDNA clone and the three auxiliary plasmids are used for performing cotransfection on 293T cells so that saved recombinant CDV-3 viruses (rCDV-3) are obtained. Through research, the highest titer of the obtained rCDV-3 virus can reach 107.667TCID50/mL, which is 10times higher than that of wtCDV-3. After Vero cells are infected with the rCDV-3, within 36h after infection, the highest virus titer can be achieved; but after the Vero cells are infected with the wtCDV-3, within 72h after infection, the virus content can reach the highest value. A base is established for developing a canine distemper virus novel vaccine and studying the infective mechanism through the canine distemper virus CDV-3 strain infectious cDNA cloning and constructing method disclosed by the invention.

Disclosed herein are chimeric genes, compositions of chimeric genes, and compositions of polypeptides that are useful for the generation, enhancement, or improvement of an immune response to a target antigen. Some embodiments of the compositions include chimeric genes encoding hepatitis D antigen (HDAg) protein in combination with one or more self-cleavage 2A polypeptides and a preS 1 polypeptide. In certain embodiments the self-cleavage polypeptide is P2A.
