Abstract:
An isolated paramyxovirus, a morbillivirus (FmoPV), isolated nucleic acids encoding the genome of FmoPV, isolated amino acid sequences of FmoPV protein, antibodies to FmoPV and its proteins, and uses thereof are provided. In certain embodiments, the modified FmoPV is a feline morbillivirus. A recombinant FmoPV comprising a modified FmoPV gene or gene segments and the use of such virus are provided. The recombinant FmoPV may be used in the prevention and/or treatment of diseases related to FmoPV or as a delivery vector. A diagnostic assay for the FmoPV is provided. In certain embodiments, the FmoPV causes kidney disease. In certain embodiments, the kidney disease is in felines. In certain embodiments, the kidney disease is tubulo interstitial nephritis ("TIN"). A quantitative assay for the detection of the FmoPV, natural or artificial variants, analogs, or derivatives thereof is provided. In certain embodiments, the quantitative assay is reverse transcription and polymerase chain reaction (RT-PCR). A vaccine and a kit containing the vaccine for the prevention and treatment of FmoPV infection are provided. A diagnosis kit that comprises nucleic acid molecules for the detection of the FmoPV is also provided.
Abstract:
The present invention encompasses NDV vaccines. The vaccine may be a subunit vaccine based on HN of NDV. The NDV HN may be expressed in plants or algae including microalgae. The invention also encompasses recombinant vectors encoding and expressing NDV antigens, epitopes or immunogens which can be used to protect animals against NDV. It encompasses also a vaccination regime compatible with the DIVA strategy, including a prime-boost scheme using viral vector or inactivated vaccines and subunit vaccines.

Abstract:
The invention provides recombinant viruses comprising heterologous envelope proteins capable of mediating entry of the recombinant viruses into host cells. In one embodiment, a recombinant virus of the invention is a member of the Paramyxovirzdae family (e.g., a respiratory syncytial virus), and the heterologous envelope protein includes the ectodomain of a baculovirus envelope protein (e.g., the GP64 protein). In some cases, the heterologous envelope protein is provided in addition to homologous envelope proteins) which may or may not be functional. The heterologous protein can provide the recombinant virus with enhanced stability (e.g., at 4 °C, 22 °C, or 37 °C), and allows production of high-titer virus stocks. The heterologous protein can also impart temperature sensitivity to the replication of the recombinant virus. In addition, the recombinant virus can be designed to be infectious but incapable of spreading between host cells by providing the heterologous protein by complementation in trans. These features attenuate the disease-causing potential of the recombinant virus, therefore increasing its safety of use as vaccines.
