HANSENULA ENGINEERING FUNGI EFFICIENTLY EXPRESSING CA10 VIRUS-LIKE PARTICLES AND USE THEREOF
The present invention provides a Hansenula engineering fungus that efficiently expresses CA10 virus-like particles and use thereof. The engineering fungus comprises a recombinant vector carrying P1 and 3CD genes of the CA10 virus, and the starting strain of the engineering fungus is uracil auxotroph. The Hansenula AU-0501, P1 and 3CD genes are optimized according to preferred codons of Hansenula. The present invention also provides a preparation method of CA10 virus-like particles, comprising: culturing engineering fungi, expressing CA10 virus-like particles, and separating and purifying virus-like particles by ultrafiltration and three-step chromatography. The CA10 virus-like particles provided by the present invention and the vaccine prepared therefrom have good immunogenicity, safety and biological activity, the process is simple, the chromatography method is adopted for purification, and large-scale preparation and purification can be realized to obtain a VLP protein stock solution with high purity (greater than 99%), which can be used to prepare a vaccine to prevent CA10 infection, with good economic value and application prospects.

Universal vaccine for viral diseases
The present invention relates to a pharmaceutical combination for inducing one or more immune responses and/or for enhancing effectiveness of vaccination in the host, which is capable of inducing cross-protection against multiples strains and/or serotypes of a virus. In one embodiment, the pharmaceutical combination is able to generate protection in food producing animals, such as cattle, sheep, goats, swine and other cloven-hoofed animals with fewer vaccination campaigns. This universal vaccine comprises an inactivated virus with one or more of the following components: polynucleotides encoding viral peptides, polypeptides or proteins in different types of plasmids; viral peptides, polypeptides and proteins; synthetic viral peptides and polypeptides; recombinant viral peptides, polypeptides and proteins; virus-like-particles; virus-like-particles derived from other viruses; proteins used as a carrier or as molecular adjuvant fused to peptides, polypeptides and/or proteins derived from viruses; adjuvants; emulsifiers, molecular adjuvants and carrier systems.
