Abstract
Since the discovery of IgY in egg yolk in late 1800s, many applications of this antibody
in diagnostics and therapeutics have been reported in human and veterinary
medicine. The mass use of antimicrobial agents in aquaculture has caused the
resistance in certain bacteria, and these fish pathogens cause tremendous economic
losses in aquaculture industry coupled with antibiotic resistance, consequently
causing barriers in international trades. IgY antibodies have been
developed for the treatment and prevention of certain fish diseases such as white
spot syndrome in shrimp, vibriosis, enteric redmouth disease and edwardsiellosis.
These antibodies are also developed for the recognition of developing and mature
stages of Loma salmonae (microsporidia) in the farmed pacific salmon. Other uses
of IgY in aquaculture include the development of sandwich ELISA for the detection
of ciguatoxin (a poisonous organic compound) in the tissues of fish, and
recently, potential sea food persevering properties of IgY have been revealed. Our
review presents an analysis of the characteristics, extraction methods, therapeutic,
detection, and seafood-persevering applications of IgY antibodies in aquaculture.
