摘要:
The present invention relates to the use of pituitary adenylate cyclase activating polypeptide (PACAP) in the treatment of viral diseases and infectious diseases caused by viruses in aquatic organisms. PACAP, alone or combined with an antiviral molecule, demonstrated its effectiveness by increasing the survival of fish or crustaceans infected by viruses when it was administered orally, by injection or by immersion baths. Furthermore, it was observed that treated organisms keep or increase its weight as compared to infected and non-treated organisms. PACAP or PACAP-containing combinations decreased the viral load in tissues and organs susceptible to viral infections as it was determined by RT-PCR.

摘要:
The present invention relates to the use of the pituitary adenylate cyclase activating peptide (PACAP) as a molecular adjuvant for vaccines. Among other applications, these vaccines may be used in the protection against infectious agents such as viruses, bacteria and ectoparasites affecting mammals, birds and aquatic organisms. The PACAP, combined with a particular antigen, demonstrates its effectiveness as adjuvant increasing the host immune response against that antigen. This type of response can be observed when the vaccine compositions or combinations that include PACAP are administered orally, by injection, or by immersion baths, in case of aquatic organisms.
摘要:
The present invention is related with the isolation and cloning of a new gene, the production of the protein encoded by this gene by using recombinant systems, and the use of this antigen in a vaccine formulation as a purified protein and/or naked DNA, to induce an immune response in aquatic organisms against different ectoparasite species, including the known as sea lice, and pathogens associated with these infestations. The vaccine preparations, administered by oral route, immersion bath or injection, demonstrated its efficacy by producing IgM humoral immune response and reducing the number of parasites per fish in the vaccinated fishes.

摘要:
The present invention is related to the use of variants of the Pituitary Adenylate Cyclase-Activating Polypeptide (PACAP) to stimulate the growth and to improve the immunological system of aquatic organisms. The variants of the peptide were provided by immersion, injection or as a food additive.
