Abstract: What is described is a recombinant vector, such as a virus; for instance, a poxvirus, such as avipox virus, containing foreign DNA from porcine reproductive and respiratory syndrome virus. What are also described are immunological compositions containing the recombinant poxvirus for inducing an immunological response in a host animal to which the immunological composition is administered. Also described are methods of treating or preventing disease caused by porcine reproductive and respiratory syndrome virus by administering the immunological compositions of the invention to an animal in need of treatment or susceptible to infection by porcine reproductive and respiratory syndrome virus.

Abstract: What is described is a recombinant poxvirus, such as avipox virus, containing foreign DNA from porcine circovirus 2. What are also described are immunological compositions containing the recombinant poxvirus for inducing an immunological response in a host animal to which the immunological composition is administered. Also described are methods of treating or preventing disease caused by porcine circovirus 2 by administering the immunological compositions of the invention to an animal in need of treatment or susceptible to infection by porcine circovirus 2.

Abstract: The avian recombinant live vaccine comprises, as vector, an ILTV virus comprising and expressing at least one heterologous nucleotide sequence, this nucleotide sequence being inserted into the insertion locus formed by the intergenic region situated between the stop codons of the ORF D and ORF E of ILTV and which, in a specific ILTV strain, is defined between nucleotides 3873 and 4260 in SEQ ID No:1. The heterologous nucleotide sequence may be under the control of a strong eukaryotic promoter, such as the CMV-IE promoter, and may be derived from the Newcastle disease virus, Marek's disease virus, the infectious bursal disease virus, the infectious bronchitis virus, the chicken anaemia virus and the chicken pneumovirosis virus. Multivalent vaccine formula comprising at least two live vaccines according to the invention. ILTV virus thus recombined.

Abstract: The living recombinant avian vaccine comprises, as a vector, an ILTV virus comprising and expressing at least one heterologous nucleotide sequence, this nucleotide sequence being inserted in the insertion locus defined between the nucleotides 1624 and 3606 at the SEQ ID NO: 5. The vaccine may in particular comprise a sequence coding for an antigen of an avian pathogenic agent selected among the group consisting of the Newcastle disease virus (NDV), the infections bursal virus (IBDV), the Marek disease virus (MDV), the infectious bronchitis virus (IBV), the chicken anaemia virus (CAV), thee chicken pneumovirosis virus, preferably under the control of a strong eukariotic promoter. A multivalent vaccine formula is also disclosed.
