Indirect ELISAs to detect exposure to Felis catus gammaherpesvirus 1 (FcaGHV1) in domestic cats. These ELISAs detect feline serum antibodies to ORF52 and ORF38 of FcaGHV1. The ELISA assays are sensitive, specific, and adaptable for scale up use in high throughput diagnostics.

The disclosure provides recombinant herpes virus with diminished latency. In embodiments, the recombinant herpes virus comprises a latency gene or transcript linked to an altered or heterologous promoter. The disclosure also provides compositions and methods for inducing immunity in animals using the recombinant herpes viruses.

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.

The present invention provides recombinant herpesvirus of turkeys (HVT) vectors that contain and express antigens of avian pathogens, compositions comprising the recombinant HVT vectors and polyvalent vaccines comprising the recombinant HVT vectors. The present invention further provides methods of vaccination against a variety of avian pathogens and method of producing the recombinant HVT vectors.

The present invention relates to a recombinant Koi herpesvirus (KHV), methods for the production of such KHV, cells comprising such KHV and the use of such KHV as vector and in vaccines for the prevention and/or therapeutic treatment of a disease in fish caused by Koi herpesvirus in carp such as Cyprinus carpio carpio or Cyprinus carpio koi.

The present disclosure provides compositions and polynucleotides for increasing expression of an immunogenic and/or antigenic polypeptide (e.g., in a vaccine). The disclosure further provides methods of using the disclosed compositions, polynucleotides, and vaccines for the treatment of diseases and disorders (e.g., infections). The compositions and polynucleotides include a first nucleic acid encoding a viral regulatory protein and a second nucleic acid encoding an immunogenic polypeptide, wherein the immunogenic polypeptide is codon-optimized to a vims from which the regulatory protein is derived.

In this study, for the first time, protective efficacy of gD against ILTV challenge was evaluated. Immunization with recombinant Newcastle disease virus expressing ILTV gD induced a higher level of neutralizing antibodies and offered complete protection to chickens against lethal ILTV challenge. Uses of recombinant NDV as a vaccine vector are also described.

The present invention relates to a recombinant Koi herpesvirus (KHV), methods for the production of such KHV, cells comprising such KHV and the use of such KHV as vector and in vaccines for the prevention and/or therapeutic treatment of a disease in fish caused by Koi herpesvirus in carp such as Cyprinus carpio carpio or Cyprinus carpio koi.

In various embodiments methods of utilizing gene drive constructs in asexual organisms such as viruses are provided. In certain embodiments the methods involve transfecting or infecting a cell with a modified DNA virus containing a gene drive construct; and infecting the cell with the target virus where the genome of said target DNA virus is modified by insertion of the gene drive construct into the genome of the target DNA virus and a population of modified target viruses (containing the gene drive construct) is produced.
