Major drawback is the proteolytic disintegration of IgY in gastric conditions when administrated through oral route. Egg yolk IgY can be labeled with horseradish peroxidase for use in immunoenzymatic assays [ 52 ]. Observations on the pathogenesis of experimental Salmonella Typhimurium infection in chickens. Enteritidis-positive eggs in the control oroduction.

Chicken Egg Yolk Antibodies, Production and Application : Reudiger Schade :

Edited by Isin Akyar. The generation and application of avian antibodies has caused a surge of interest in a wide variety of applications within the life sciences [ 1 ]. Nowadays, most classical chosen mammals for polyclonal and monoclonal antibodies are rabbits and mice, respectively.

Conformational state of chicken 7S immunoglobulin. Methods2 IgY sampling is eegg invasive, which confers advantage on IgG; also, yolk antibody does not interfere with rheumatoid factor or activate mammalian complement [ 1 ].

Description Polyclonal antibodies, widely used in research and diagnostics, are conventionally isolated from the blood of immunised mammals. Chicken egg igj antibodies IgY-technology: A high quality removing lipid method is the first step to efficiently isolate IgY antibodies from egg yolk.


Laying hens are very efficient producers of specific antibodies. Principles of Peptide Synthesis Miklos Bodanszky.

Other possibility for the use of IgY to proteomic studies is screening random peptide phage display library to detect new chickne candidates to be applied for diagnostic methods to widespread parasitic human diseases [ 46 ].

The isolation of IgY from yolk using of combination of different methods results in a high amount of specific antibodies with elevated purity. Several of these techniques could be included in one total clean-up procedure. Productivity and some properties of immunoglobulin specific against Streptococcus mutans serotype C in chicken egg yolk IgY. The industry however is under pressure and faces many antibldies. Oral administration of antibodies as prophylaxis and therapy in Campylobacter jejuni -infected chickens.

In vitro and in vivo studies showed that anti- P. In addition, an immune humoral response must be elicited by immunization with recombinant proteins [ 9 ] or peptides [ 10 ]. NaS or AmS precipitation provides fractions with low protein content compared to original yolk, but with a high specific activity [ 26 ]. Microencapsulation protects immunoglobulin in yolk IgY specific against Helicobacter pylori urease. Passive immunity can occur naturally, when maternal antibodies are transferred to the offspring.

The IgY acts by enhancing the phagocytic ability macrophages and inhibition of growth and colonization of bacteria 19 Thus prospective immunotherapeutic role of specific IgY in preventing this important infection in shrimp has been suggested. Oral administration of IgY have been useful in controlling infectious diseases of bacterial and viral origin 35 Acta44 We use cookies to give you the best possible experience.


The extraction of yolk antibodies by the use of polyethylene glycol precipitation PEG, MW was, firstly, developed by Polson et al. It is becoming a more and more interesting alternative to control the increasing number of antibiotic-resistant organisms.

IgY-Technology Applied to Studies of Toxoplasma gondii Infection

Both avian and mammalian antibodies have structure similarity. Specific IgY development and production can be achieved by immunizing laying-hens with the target antigen. The fact that technologg can also be detected in the yolk of eggs laid by immunised hens, led to the development of the yolk antibody technology as an alternative method less stressful to animals.

ALTEX13 5produftion Oral administration of IgY antibodies has been tested for many years with promising results [ 80 ] to different pathogens as human rotavirus [ 81 ]; dental plaque formation by Streptococcus mutans [ 8283 ]; enteropathogenic E. General layout to produce specific IgY antibodies.

Thus this study revealed the potential of IgY against V. Passive immunization of rainbow trout Oncorhynchus mykiss with chicken egg yolk immunoglobulins IgY. ATLA33 Specific antisnake venom IgY with neutralizing effect for therapeutic proposes can be isolated by AmS precipitation followed to ion exchange chromatography [ 3233 ]. Increasing problems of emerging bacterial resistance issue and the presence of drug residues in fish products poses food safety and public health concerns.
