Identification of the major mannose-binding proteins from chicken egg yolk and chicken serum as immunoglobulins.
Chicken egg yolk contains a mannose-binding protein that could be purified with a modification of the procedure of affinity chromatography and gel filtration used for chicken serum mannose-binding protein. The yolk protein was indistinguishable from the serum protein with respect to apparent molecular masses (169 +/- 7 kDa), subunits (74 kDa and 27 kDa, in approximately 1:1 ratio) produced afte...
متن کاملProduction, Characterization and Applications for Toxoplasma gondii-Specific Polyclonal Chicken Egg Yolk Immunoglobulins
BACKGROUND Toxoplasma gondii may cause abortions, ocular and neurological disorders in warm-blood hosts. Immunized mammals are a wide source of hyperimmune sera used in different approaches, including diagnosis and the study of host-parasite interactions. Unfortunately, mammalian antibodies present limitations for its production, such as the necessity for animal bleeding, low yield, interferenc...
متن کاملTherapeutic Efficacy of Chicken Egg Yolk Immunoglobulins Against Mycoplasma gallisepticum Infection in Chickens
The focus of this report was to assess the role of passive immunization using immunoglobulins derived from chicken egg yolk in protection against M. gallisepticum infection in chickens. Immunoglobulins were produced by egg yolk technology. ELISA was used to evaluate their immunoreactivity and western immunoblotting demonstrated that chicken egg yolk immunoglobulins Y (IgY) were capable of recog...
متن کاملPassive protection effect of chicken egg yolk immunoglobulins on enterovirus 71 infected mice.
The objective of this study is to evaluate the passive protective efficiency of immunoglobulin in yolk (IgY) specific against human enterovirus type 71 (EV71). The antibody was raised by intramuscular immunization to 10 White Leghorn hens, with inactivated human EV71 serving as the antigen. The titer and specificity of the antibody were analyzed from purified IgY in the egg yolks of immunized h...
متن کاملSpecific Chicken Egg Yolk Antibodies against Enterotoxigenic Escherichia coli K99 in Serum and Egg Yolk of Immunized Laying Hens
Enterotoxigenic Escherichia coli K99 is one of the dominant pathogens associated with diarrhea of calves. Immunoglobulin Y (IgY), has been used as an inexpensive alternative to antibiotics for the prevention and therapy of several bacterial infections. The study aimed to prepare IgY antibodies against E. coli K99 and to investigate its in vitro effectiveness. E. c...
