Abstract: Provided herein are immunogenic compositions containing recombinant viruses capable of inducing protection in poultry against both Marek's disease virus (MDV) and Newcastle disease virus (NDV). Such viruses incorporate nucleic acids for expressing at least one MDV antigen, such as glycoprotein B, and antigenic portions thereof, in a recombinant NDV genome.

Abstract: An altered avian NDV that contains the coding sequence of avian interleukin-4 (IL-4), or a portion thereof, in the reverse orientation suppresses in-ovo IL-4 production via RNAi when administered to embryonic birds. An immunogenic composition containing this altered NDV is included in this invention. The altered avian NDV can, optionally contain a polynucleotide encoding a heterologous antigen from a heterologous avian pathogen and can produce said heterologous antigen in-ovo.

Abstract: Recombinant chimeric viruses based on NDV LaSota strain and containing either ILTV gB or gD are produced. Administration of the chimeric viruses to chickens induces an immune response in the animal against both NDV and ILTV. Immunogenic compositions, plasmids, kits and methods are described.

Abstract: Disclosed are compositions, vectors, kits, and methods for inducing an immune response against avian infectious bronchitis virus (IBV). In particular, the compositions, vectors, kits, and methods may be utilized to immunize poultry against disease associated with IBV infection or to protect poultry from IBV infection altogether.

Abstract: The present invention relates to poultry vaccines for prevention of Newcastle disease.

Abstract: Recombinant methods for recovering wildtype or engineered negative stranded, non-segmented RNA virus genomes containing non-coding 3' and 5' regions (e.g. leader or trailer regions) surrounding one, several or all of the genes of the virus or one or more heterologous gene(s) in the form of ribonucleocapsids containing N, P and L proteins, which are capable of replicating and assembling with the remaining structural proteins to bud and form virions, or which are only capable of infecting one cell, or are transcribing particles, are disclosed. Novel vaccines, gene therapy vectors and antiviral compounds based on these viral particles are also disclosed.
