Production of Specific Egg Yolk Antibody (IgY) against Cryptosporidium parvum Oocysts
ABSTRACT Background and Objectives: Cryptosporidium parvum is a coccidian protozoan that causes diarrhea in immunocompromised humans and newborn animals. The severity of the disease depends on the immunological status of the affected. Cryptosporiosis can have lethal effects on immunocompromised individuals such as AIDS patients. About 10% of...
متن کاملEffects of egg and yolk weights on yolk antibody (IgY) production in laying chickens.
Twenty 35-wk-old chickens, including 10 Single Comb White Leghorn (SCWL) and 10 Rhode Island Red (RIR) hens, were used to examine the effects of egg and yolk weights on egg yolk antibody (IgY) production in the two strains of chickens immunized with BSA. The SCWL chickens had a greater (P < 0.01) percentage hen-day production and greater egg and yolk weights than did the RIR chickens. However, ...
متن کاملHen egg yolk antibodies (IgY), production and use for passive immunization against bacterial enteric infections in chicken: a review
Poultry meat is an important food product and the broiler chicken-related industry is an economically important component of the agro-industry in the European Union (EU). The industry however is under pressure and faces many challenges. Most importantly, there is a demand for meat of high nutritional value and free of microbiological and chemical hazards. Unfortunately poultry meat is one of th...
متن کاملEgg Yolk Antibodies (IgY) in Routine Diagnostic Work.
According to Linscott"s Directory of Immunological and Biological Reagents (1994/95) the commercial availability of egg-yolk antibodies (IgY) is extremely low. For preparation, cleaning and detection of IgY it would be of advantage to have a "Protein Y" available analogous to protein A and protein G for mammalian antibodies. Until now, the search for "Protein Y" was unsuccessful. IgY has been u...
متن کاملProduction of Egg Yolk Antibody (IgY) against Recombinant Porcine Epidemic Diarrhea Virus COE Protein
Background: Porcine epidemic diarrhea (PED) is a highly contagious disease of pigs, and is characterized by a series of clinical symptoms, such as severe diarrhea, vomiting and dehydration. Partial protective antigen gene (COE gene) of S protein possessing the main B cell epitope, is able to encode proteins with reactogenicity to induce the production of neutralizing antibodies. IgY was found t...
