摘要:
Peptidic chemical compounds obtained by in silico molecular modelling, having a structure that enables them to perform the same functions of peptidic growth hormone secretagogues. The invention also comprises the preparations containing such compounds and the use in medicines, food additives, nutritional supplements or other formulations of human or animal use.
摘要:
The present invention is related to the use of variants of the Pituitary Adenylate Cyctase-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.
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 antimicrobial peptides, isolated and purified from extracts of tilapia ( Oreochromis niloticus ) gills. Such peptides may be produced by chemical synthesis or by expression in heterologous systems, such as bacteria and yeasts, by conventional molecular biology techniques. These peptides show antimicrobial activity against various organisms, including Gram positive bacteria, Gram negative bacteria, fungi and viruses. The invention also includes compositions for controlling pathogens comprising these antimicrobial peptides. The use of such peptides in vaccine preparations, as molecular adjuvants, is also part of the invention.
