Transfer of Chicken Immunoglobulin Y (IgY) from the Hen to the Chick

Avian Biology Research, 2012
Chicks depend on maternal antibodies as the main source of passive natural humoral protection until they become immunocompetent. Immunoglobulin Y (IgY), the avian homologue of mammalian IgG is transferred from the circulation of the hen into the egg yolk and then absorbed by the embryo. In the post-hatching period, protein integrity within the yolk sac

Development of anti-Helicobacter pylori immunoglobulins Y (IgYs) in quail.

Iranian journal of veterinary research, 2016
Helicobacter pylori (H. pylori) is a gram-negative, microaerophilic bacterium that cause the stomach infection in more than 50% of human population worldwide. The aim of this study was to examine the possibility of anti-H. pylori immunoglobulins Y (IgYs) production in quails and evaluate the effect of the different methods of immunization on titers of ...

Isolation of Nile crocodile (Crocodylus niloticus) serum immunoglobulin M and Y (IgM and IgY)

Journal of Immunological Methods, 2020
Crocodile immunity has not been fully characterised with more studies on crocodile innate immunity than cell-mediated or humoral immunity. Crocodile immunoglobulin genes have been described but immunoglobulin proteins have not been isolated or studied biochemically. Two large proteins proposed to be crocodile IgM and IgY were isolated and purified from

The protective efficacy of specific egg yolk immunoglobulin Y(IgY) against Riemerella Anatipestifer infections

Veterinary Microbiology, 2020
Riemerella anatipestifer (RA) is the significant pathogen of septicemia and duck infectious serositis, diseases which can result in high mortality for ducklings. However, these diseases are difficult to treat because of the bacteria's broad resistance to multiple drugs. The purpose of this study was to produce a specific egg yolk immunoglobulin Y (IgY)

An easy and simple separation method for Fc and Fab fragments from chicken immunoglobulin Y (IgY)

Journal of Chromatography B, 2020
Antigen-binding (Fab) and crystallizable (Fc) fragments are the active components of yolk immunoglobulin (IgY), which have been widely used in the pharmaceutical field. However, the common purification methods for the Fab and Fc fragments use combinations of multi-columns are complex and time-consuming.

Leptospira-specific immunoglobulin Y (IgY) is protective in infected hamsters

Vaccine
Leptospirosis, a globally significant zoonotic disease caused by pathogenic Leptospira, continues to threaten the health and public safety of both humans and animals. Current clinical treatment of leptospirosis mainly relies on antibiotics but their efficacy in severe cases is controversial. Passive immunization has a protective effect in the treatment

Production and purification of Fab′ fragments from chicken egg yolk immunoglobulin Y (IgY)

Journal of Immunological Methods, 1993
Methods were described for the production of Fab and Fab' fragments from chicken egg yolk IgY also referred to as IgG by papain and pepsin digestion respectively. Pepsin digestion was found to be suitable for the large scale preparation and purification of Fab'.

Method of Immunoglobulin Y (IgY) Extraction for Minimally Toxic In Vivo Applications

Philippine Journal of Science
Although immunoglobulin (IgY) has therapeutic potential, extracts from conventional methods are generally parenterally incompatible. This present study aimed to design a method to generate an IgY composition in vivo administration. The proposed procedure incorporated the following modifications: delipidation using carrageenan, salt precipitation using ...

In-Vitro and In-Vivo Binding Activity of Chicken Egg Yolk Immunoglobulin Y (IgY) against Gliadin in Food Matrix

Journal of Agricultural and Food Chemistry, 2012
Chicken egg yolk immunoglobulin Y (IgY) is a promising alternative for the prevention of enteric gliadin absorption, the predisposing factor of celiac disease (CD). IgY antibody was produced from the egg yolk of Single Comb White Leghorn chickens during the immunization period for the development of an oral immunotherapeutic agent.
