The present invention relates to the use of an immunogenic composition that comprises a porcine circovirus type 3 (PCV3) antigen for treatment of several clinical manifestations (diseases). Preferably, the clinical manifestations are associated with a PCV3 infection.

This invention relates to a method of treating a dog for canine diseases comprising administering to the dog therapeutically effective amounts of a vaccine, wherein the vaccine comprises viral antigens, a bacterin, or both, and wherein the vaccine is administered subcutaneously or orally according to the schedules provided herein.

A vaccine delivery method is presented that includes a composition including as one component a slurry matrix that is a liquid at room temperature and a gel at physiological pH, physiological salt concentrations and/or physiological temperatures and as a second component one or more antigens. Also included are methods of inducing an immune response in a subject and vaccinating a subject by administering such compositions.

This invention relates to a method of treating a dog for canine diseases comprising administering to the dog therapeutically effective amounts of a vaccine, wherein the vaccine comprises viral antigens, a bacterin, or both, and wherein the vaccine is administered subcutaneously or orally according to the schedules provided herein.

The present invention discloses a combination of vaccine strains for treating, preventing, relieving or controlling Canine Distemper, Canine Parvovirus Enteritis and Canine Infectious Hepatitis, comprising: Canine Distemper virus vaccine strain with the microorganism deposition accession number CGMCC No. 19397, Canine Parvovirus vaccine strain with the microorganism deposition accession number CGMCC No. 19398 and Canine Infectious Hepatitis virus vaccine strain with the microorganism deposition accession number CGMCC No. 19396. The three vaccine strains of the combination of vaccine strains are low in toxicity and good in immunogenicity. The present invention further discloses a live vaccine composition using the above-mentioned combination of vaccine strains as immunogen. The vaccine composition is safe and effective.

The present disclosure provides a canine parvovirus (CPV) nanobody CPV-VHH-H1 and use thereof, belonging to the technical field of immunology. A heavy-chain variable region sequence of the nanobody CPV-VHH-H1 has the amino acid sequence set forth in SEQ ID NO: 1; and a gene encoding the nanobody CPV-VPP-H1 has the nucleotide sequence set forth in SEQ ID NO: 2. In the present disclosure, a nanobody immune library of the CPV is constructed by a phage display technology, a specific anti-CPV nanobody CPV-VHH-H1 is obtained by screening, and it is verified by experiments that the nanobody may specifically bind to the CPV. The present disclosure is expected to develop a new nanobody preparation for use in clinical diagnosis and treatment of the CPV, and provides a certain theoretical reserve for applying the nanobody to the field of veterinary biological products.

The present invention discloses dry formulations of room temperature stable vaccines that comprise a live attenuated virus, a sugar stabilizer, and an amino acid stabilizer. The present invention also discloses the manufacture of such vaccines and methods of protecting an animal by administration of such vaccines.

The present invention provides novel nucleotides sequences, protein sequences, immunogenic compositions, vaccines, and methods that relate to making and using new porcine parvovirus 5B (PPV5B) that infects, inter alia, domestic swine. The compositions and methods provide for the detection of infections by said new virus, monitoring genetic changes in the viral sequences in wild and domestic animals and herds, and making and using novel vaccines for protecting animals from infection by the virus.

An improved vaccine for immunization of waterfowl such as ducks and geese comprises an inactivated strain of a Mycoplasma infecting waterfowl, such as Mycoplasma sp. strain 1220; the vaccine can include an excipient and an adjuvant. Methods for immunization of waterfowl with the vaccine are also described.
