    摘要: The present invention discloses the production of recombinant proteins of the virus causing the porcine respiratory and reproductive syndrome (PRRS), corresponding to the OFR s 2-7 of the PRRSV isolated in Spain, (PRRS-Olot), in a system of expression of recombinant baculoviruses multiplided in a cell culture of a permissive host . Said recombinant proteins are appropriate to formulate vaccines capable of efficiently protecting pigs'against PRRS as well as to prepare diagnostic kits appropriate to detect both the presence of antibodies which recognize PRRSV and the presence of PRRSV in a porcine biological sample. This invention applies to veterinary.

    摘要: The invention relates to arterivirus compositions used as vaccines to induce protective immunity against infection or disease caused by arteriviruses. Provided is a vaccine directed against infection or disease caused by an arterivirus, said vaccine comprising an arterivirus provided with a modification in a nucleic acid sequence allowing to distinguish animals vaccinated with said vaccine from animals infected with wild-type arterivirus or vaccinated with an unmodified arterivirus strain. Also provided is a method for distinguishing unvaccinated animals or animals vaccinated with a vaccine according to the invention from animals infected with wild-type arterivirus or vaccinated with an unmodified arterivirus strain.

    摘要: The invention relates to the field of virology , more in particular to the field of vaccine production, more specifically to the in vitro propagation of virus, more specifically to the adaptation of virus to a cell line.
    The invention provides a method to determine the capability of an arterivirus to replicate in a green monkey cell line, comprising determining the amino acids at positions, which correspond to the amino acid positions 75-107 of GP2a of PRRSV isolate I-1102, more specifically amino acid position 88 and/or amino acid position 95 of said GP2a. The invention further discloses a method to produce arterivirus in green monkey cell line wherein the virulence of said arterivirus is maintained, with increased virus yield.
    The invention further provides a method to determine the attenuation of an arterivirus, comprising determining the amino acids at positions, which correspond to the amino acid positions 121-148 of GP5 of PRRSV isolate I-1102, more specifically amino acid 136 of said GP5 and/or determining the amino acids at positions, which correspond to the amino acid positions 651-675 and/or amino acid positions 2331-2355 of ORF1ab of PRRSV isolate I-1102, more specifically amino acid 663 and/or 2343 of said ORF1ab. The invention also provides a method to attenuate the virulence of said arterivirus by changing said amino acids.

    摘要: The present invention concerns a method of genetic modification of a TGB-3 wild type viral sequence for reducing or suppressing the possible deleterious effects of the agronomic properties of a transformed plant or plant cell by said TGB-3 viral sequence, comprising the following successive steps: submitting said sequence to point mutation(s) which allow the substitution of at least one amino-acid into a different amino-acid; selecting genetically modified TGB-3 wild type viral sequences having said point mutation(s) and which are not able to promote cell-to-cell movement of a mutant virus having a dysfunctional TGB-3 wild type viral sequence, when expressed in trans from a replicon; further selecting among said genetically modified TGB-3 viral sequences, the specifically genetically modified sequence which inhibits infection with a co-inoculated wild type virus when the mutant form was expressed from a replicon; and recovering said specifically genetically modified TGB-3 viral sequence.
