Specific 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...
متن کاملProduction 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 کاملGenetic diversity of Gallibacterium anatis isolates from different chicken flocks.
Amplified fragment length polymorphisms (AFLPs) were used to characterize the genotypic diversity of a total of 114 Gallibacterium anatis isolates originating from a reference collection representing 15 biovars from four countries and isolates obtained from tracheal and cloacal swab samples of chickens from an organic, egg-producing flock and a layer parent flock. A subset of strains was also c...
متن کاملspecific egg yolk antibody against recombinant cryptosporidium parvum p23 protein
background: cryptosporidium parvum is a parasitic protozoan that functions as important causative agent of diarrhea in human and animals. the host's immune response to surface antigens of c. parvum has been previously demonstrated. in this respect, the role of humoral immunity in the development of host protective immunity against this protozoon has been well demonstrated. methods: the effe...
متن کاملRecombinant proteins from Gallibacterium anatis induces partial protection against heterologous challenge in egg-laying hens
Gallibacterium anatis is a Gram-negative bacterium and major cause of salpingitis and peritonitis in egg-laying hens, thereby contributing to decreased egg production and increased mortality among the hens. Due to widespread drug resistance and antigenic diversity, novel prophylactic measures are urgently required. The aim of the present study was to evaluate the cross-protective capacity of th...
