Abstract:
The present invention is directed to novel nucleotide and amino acid sequences of Torque teno virus (“TTV”), including novel genotypes thereof, all of which are useful in the preparation of vaccines for treating and preventing diseases in swine and other animals. Vaccines provided according to the practice of the invention are effective against multiple swine TTV genotypes and isolates. Diagnostic and therapeutic polyclonal and monoclonal antibodies are also a feature of the present invention, as are infectious clones useful in the propagation of the virus and in the preparation of vaccines. Particularly important aspects of the invention include vaccines that provide TTV ORF1 protein, or peptide fragments thereof, as antigen.
Abstract:
The present invention provides four purified preparation containing a polynucleic acid molecule encoding porcine Torque teno virus (PTTV) genotypes or subtypes PTTV1a-VA, PTTV1b-VA, PTTV2b-VA, and PTTV2c-VA. The present invention also provides infectious DNA clones, biologically functional plasmid or viral vector containing the infectious nucleic acid genome molecule of the same. The present invention further provides live, attenuated, vector-expressed and purified recombinant capsid subunit or killed viral vaccines for protection against PTTV infection. The present invention additionally provides subunit vaccines comprising PTTV specific gene products, especially ORF1 capsid gene product for protection against PTTV infection. Further, the present invention provides methods for diagnosing PTTV infection via polymerase chain reaction (PCR) using specific primer for PTTV1, PTTV2, and individual PTTV1 genotypes. Finally, the present invention provides methods for diagnosing PTTV infection via immunological methods, e.g., enzyme-linked immunoabsorbent assay (ELISA) and Western blot using PTTV specific antigens for detecting serum PTTV specific antibodies.
Abstract:
The present invention relates to rearranged molecules of (a) a specific TT virus sequence and (b) a nucleotide sequence encoding a polypeptide showing homology to mammalian proteins associated with cancer and autoimmune diseases that are capable of replicating autonomously for use in diagnosis, prevention and treatment of diseases like cancer and autoimmunity.

Abstract:
This invention relates generally to compositions for making anellovectors and uses thereof. For instance, a method herein can comprise providing a nucleic acid construct that comprises a first Anellovirus genome encoding an exogenous effector and a second Anellovirus genome or fragment thereof, arranged in tandem. In some embodiments, the nucleic acid construct results in production of an anellovector comprising an Anellovirus genetic element encoding the exogenous effector, enclosed in a proteinaceous exterior.
Abstract:
The present invention relates to the novel Porcine Circovirus type 2 subtype B (PCV2B-Rm) isolate which comprises a short duplication of sequence and is adapted to grow in cell culture and may be propagated at high titres constantly up to 106 TCID50 viral particles per mL. This novel isolate is particularly useful for the production of porcine circovirus type 2 (PCV2) vaccines, for treating and/or preventing and/or diagnosing porcine circovirus associated diseases, as well as for diagnosing the presence of porcine circovirus in pigs. The present invention also relates to novel cell clones derived from Swine Testicles (ST) useful for propagating PCV2 and to a method for production of PCV2 virus with particularly high titers.
