Immunogenicity of eGFP-Marked Recombinant Lactobacillus casei against Transmissible Gastroenteritis Virus and Porcine Epidemic Diarrhea Virus
Porcine transmissible gastroenteritis virus (TGEV) and porcine epidemic diarrhea virus (PEDV) are the causative agents of highly fatal acute diarrhea in pigs, resulting in enormous losses in the pig industry worldwide. To develop an effective bivalent oral vaccine against TGEV and PEDV infection, the D antigenic site of the TGEV spike (S) protein and the major antigen site (core neutralizing ep...
متن کاملproduction and purification immunoglobulin against e. coli in egg yolk
introduction chicken is the only avian species in which polyclonal antibodies, like igg is transported from the hen to the egg yolk in a similar manner as the transport of mammalian igg from the mother to the fetus. immunoglobulin y in the chicken is transported to the egg and accumulates in the egg yolk in large quantities. igy is an egg yolk antibody that has been used widely for treatment an...
متن کاملThe Porcine MicroRNA Transcriptome Response to Transmissible Gastroenteritis Virus Infection
Transmissible gastroenteritis virus (TGEV; Coronaviridae family) causes huge economic losses to the swine industry. MicroRNAs (miRNAs) play a regulatory role in viral infection and may be involved in the mammalian immune response. Here, we report a comprehensive analysis of host miRNA expression in TGEV-infected swine testis (ST) cells. Deep sequencing generated 3,704,353 and 2,763,665 reads fr...
متن کاملIsolation of porcine immunoglobulins and determination of the immunoglobulin classes of transmissible gastroenteritis viral antibodies.
The porcine immunoglobulins M (IgM), A (IgA), and G (IgG) were isolated and purified and some of the properties of the porcine milk IgA were examined. Monospecific antisera which were prepared against these immunoglobulins in rabbits were then used to absorb a particular class of immunoglobulin from sow serum, colostrum, and milk in an attempt to identify the immunoglobulin classes of neutraliz...
متن کاملIsolation of Porcine Immunoglobulins and Determination of the Immunoglobulin Classes of Transmissible Gastroenteritis Viral Antibodies1
serum, colostrum, and milk in an attempt to identify the immunoglobulin classes of neutralizing antibodies to the porcine enteric virus, transmissible gastroenteritis (TGE). The results of these absorption studies suggest that in colostrum and milk from sows experimentally (orally) or naturally infected with live virulent TGE virus, IgA is the predominant immunoglobulin class of TGE antibodies....
