The cell line is highly susceptible to feline parvovirus, feline calicivirus, feline herpes virus, canine parvovirus and canine distemper virus, the virus content of a virus solution harvested 72 h after FPV virus inoculation can reach 107.5 TCID50 / mL, the virus content of a virus solution harvested 24 h after FCV virus inoculation can reach 1010.8 TCID50 / mL, the virus content of a virus solution harvested 48 h after FHV-1 virus inoculation can reach 107.5 TCID50 / mL, compared with an existing F81 adherent cell production process, the production process has the advantages that the production efficiency is high, and the production cost is low. The method has the characteristics of rapid lesion, short virus collection time and high titer. The cell matrix is an ideal cell matrix which can be used for culturing the three viruses.

The invention discloses a primer group and a kit for simultaneously detecting a panda aleutian virus and a panda canine distemper virus Asia type 6 and application of the primer group and the kit, and belongs to the technical field of virus detection of endangered wild animals. The invention provides a primer group and a kit for specifically recognizing the aleutian disease virus and the canine distemper virus Asia 6 type of the panda, and detection can be completed within 20 minutes under the condition of constant temperature of 39 DEG C; according to the present invention, the method has characteristics of rapid detection, good specificity, high sensitivity and the like, does not produce the cross reaction with other common pathogens, does not produce the false positive phenomenon due to the generation of the primer dimer, has characteristics of rapid detection, good specificity, high sensitivity and the like, and has characteristics of simple and easy operation, and on-site detection without special detection personnel; the method is rapid and accurate in detection, has a good application effect in preliminary application, and provides a method for rapid diagnosis, virus traceability, epidemic disease monitoring and early warning of a wild animal epidemic disease source and the like in zoos and wild animal rescue institutions.

This invention discloses a primer set, reagent kit, and their applications for the simultaneous detection of Aleutian virus and Canine Distemper Virus Asia 6 (Asia 6) in red pandas, belonging to the field of endangered wildlife virus detection technology. This invention provides a primer set and reagent kit that specifically identifies Aleutian virus and Canine Distemper Virus Asia 6 in red pandas. Detection can be completed within 20 minutes under constant temperature conditions of 39℃; it does not cross-react with other common pathogens and does not produce false positives due to primer dimer formation. In other words, it features rapid detection, high specificity, and high sensitivity. The implementation process is simple and easy to operate, requiring no specialized testing personnel for on-site testing. The detection is rapid and accurate, and initial applications have shown good results, providing a method for rapid diagnosis, virus tracing, wildlife disease monitoring, and early warning in zoos and wildlife rescue institutions.

The invention discloses a probiotic fermented traditional Chinese medicine composition for preventing and controlling canine distemper and a preparation method of the probiotic fermented traditional Chinese medicine composition, and belongs to the technical field of fermented compositions. The feed additive is prepared from the following raw materials in parts by weight through fermentation: 100 to 200 parts of cortex phellodendri, 10 to 20 parts of radix aucklandiae, 100 to 200 parts of liquorice root, 200 to 400 parts of herba taraxaci, 100 to 200 parts of rhizoma coptidis and 10 to 40 parts of a microbial preparation. The microbial preparation comprises bacillus licheniformis SXDYYB15, the bacillus licheniformis SXDYYB15 is preserved in the China Center for Type Culture Collection on April 18, 2025, and the preservation number of the bacillus licheniformis SXDYYB15 is CCTCC (China Center for Type Culture Collection) NO: M2025814. The composition breaks through the bottleneck that the traditional Chinese medicine takes effect slowly through a triple synergistic mechanism of traditional Chinese medicine antivirus, probiotic immunoregulation and gastrointestinal function repair; on the premise of adapting to the canine intestinal environment, the pharmacodynamic bioavailability is remarkably improved through directional fermentation, and an efficient, safe and economical solution is provided for prevention and control of canine distemper.

The present invention provides a recombinant canine distemper virus vector comprising a heterologous polynucleotide encoding an avian influenza antigen. The recombinant viral vectors are suitable for use in immunogenic compositions and vaccines that can provide protection against avian influenza and other pathogens when administered to animals.

A giant panda canine distemper virus detection kit based on multi-enzyme isothermal nucleic acid rapid amplification technology and a use method are provided. For CDV, the kit selects virus conserved gene, designs specific primers in the conserved region of the gene, amplifies the N gene fragment of CDV by multi-enzyme isothermal rapid amplification technology, and then detects the amplified products with nucleic acid colloidal gold test strips to establish a MIRA detection method for rapid auxiliary diagnosis with CD.
