Expression, purification, and immunization of a chimeric protein containing immunogenic regions of flagellin and intimin proteins against E. coli O157: H7

Introduction: Enterohemorrhagic Escherichia coli (EHEC) and serotype O157: H7 is one of the most important diseases causing diarrhea. Shiga-like toxin secreted by the bacteria destroys epithelial cells and, in acute cases, causes hemolytic uremic syndrome (HUS). Antibiotic therapy is not effective against this pathogen, because it increases the production of Shiga toxin. Designing chimeric immu...

Evaluation of Humoral and Cell-mediated Immunity of Two Capripoxvirus Vaccine Strains against Lumpy Skin Disease Virus

Background and Aims: Prevention of Lumpy skin disease (LSD) in cattle is heavily dependent on vaccination. Since the genetic structure of LSD virus has the close relatedness with other Capri-pox virus (CaPV). Therefore, the use of vaccine strains of CaPV derived from sheep and goat would be useful to protect cattle against LSD. Materials and Methods: The susceptible calves of dairy farms were ...

Analyzing immunity against hepatitis A in 6-11 years old children in Kerman county

Introduction: Hepatitis A is caused by a virus with a similar name. As a very contagious disease, Hepatitis A is one of the most prevalent infant infections across the developing countries. People who have been vaccinated and also those who caught this disease already are immune against hepatitis A. Since it was not possible and cost effective to analyze the immunity level of all asymptomatic c...

Expression of an epitope-based recombinant vaccine against Foot and Mouth Disease (FMDV) in tobacco plant (Nicotiana tabacum)

Regarding high potential of green plants for development of recombinant vaccines, this research was conducted to evaluate expression of a novel recombinant vaccines against Foot and Mouth Disease (FMDV) in tobacco plant. For this purpose, a synthetic gene encoding 129-169 amino acids of foot and mouth disease virus capsid protein VP1 was transferred to tobacco plant via Agrobacterium-mediated g...
