GENERATION AND PHYSICOCHEMICAL CHARACTERIZATION OF CHICKEN EGG YOLK ANTIBODIES (IgY) AGAINST Salmonella typhimurium
Salmonellosis is one of the most important bacterial diseases with economic concern to all phases of the poultry. The study was aimed to generate chicken IgY against Salmonella typhimurium and its physicochemical characterization to unbolt the obstacles for the usage of IgY as therapeutic agent in Poultry. Salmonella typhimurium whole cell antigen was prepared and immunized in white leghorn chi...
متن کاملImmunogenicity 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 کاملField validation of a commercial blocking ELISA to differentiate antibody to transmissible gastroenteritis virus (TGEV) and porcine respiratory coronavirus and to identify TGEV-infected swine herds.
A commercially available blocking ELISA was analyzed for its ability to identify antibodies to porcine coronaviruses (transmissible gastroenteritis virus [TGEV] or porcine respiratory coronavirus [PRCV]), to differentiate antibodies to TGEV and PRCV, and to identify TGEV-infected herds. Nine sera from uninfected pigs, 34 sera from 16 pigs experimentally infected with TGEV, and sera from 10 pigs...
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...
متن کاملTransmissible Gastroenteritis Virus (TGEV) Infection Alters the Expression of Cellular MicroRNA Species That Affect Transcription of TGEV Gene 7
Transmissible gastroenteritis virus (TGEV) is a member of Coronaviridae family. TGEV infection has emerged as a major cause of severe gastroenteritis and leads to alterations of many cellular processes. Meanwhile, the pathogenic mechanism of TGEV is still unclear. microRNAs (miRNAs) are a novel class of small non-coding RNAs which are involved in the regulation of numerous biological processes ...
