background and objective: enterohemorrhagic escherichia coli (ehec) o157:h7 is an important enteric pathogen in human causing bloody or nonbloody diarrhea, which may be complicated by hemolytic uremic syndrome (hus). cattle are an important reservoir of ehec. this research aims at vaccination with a divalent chimer protein composed of espa 120 and intimin 282 and its preventive effect of ehec o...
objective(s):brucellosis, especially caused by brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500,000 human cases reported annually. the commonly used live attenuated vaccine in ovine brucellosis prophylaxis is b. melitensis rev1. but due to different problems caused by the administration of this vaccine, a protective subunit vaccine against b. me...

Background: Hepatitis C virus (HCV) causes acute and chronic human hepatitis infections. Due to the high genetic diversity and high rates of mutations in the genetic material so far there is no approved vaccine against HCV. Materials and Methods: The aim of this study was to determination B and T cell conserved epitopes of E1 and E2 proteins from HCV and construction of a chimeric pepti...
background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...
Background & Objective: Enterotoxigenic Escherichia coli (ETEC) is a major causative agent of diarrhea. Enterotoxins and the colonization factors (CFs) are major virulence factors in ETEC infections. The bacterium binds to the intestinal epithelial cell surface through colonization factors and produces enterotoxins that cause excessive fluid and electrolyte secretion in the lumen of the intesti...
Introduction: To date, many vaccines have been developed for anthrax but not yet an ideal vaccine. In this study, chimeric protein containing domain 1 lethal factor and domain 4 protective antigens of Bacillus anthracis in copolymer nanocapsules were used to solve the problems caused by existing vaccines and to increase the efficiency of the proposed vaccine. Materials and Methods: In this expe...
Introduction bacteria species; Burkholderia pseudomallei, Vibrio cholera, and Shigella dysenteriae are the main pathogen causing Melioidosis, Cholera, and Shigella in humans respectively. bacterial species have a protein that has antigenic prosperities along with being a mucus based adjuvant thus easing their delivery and immunogenicity. These proteins were BLF1(B. pseudomallei), CTxB (V. cho...
Based on the life-time cost to the health care system, the Institute of Medicine has assigned the highest priority for a vaccine to control human cytomegalovirus (HCMV) disease in transplant patients and new born babies. In spite of numerous attempts successful licensure of a HCMV vaccine formulation remains elusive. Here we have developed a novel chimeric vaccine strategy based on a replicatio...
Intensive efforts to improve vaccines against cancer are currently outgoing. Mucin 1 (Muc1) is a tumor-specific antigen that is overexpressed and heavily glycosylated in a variety of adenocarcinomas. In the present study, the efficacy of an anticancer DNA vaccination strategy was demonstrated using Muc1 fusion vaccines. To enhance antigen presentation and tumor-suppressive efficacy, a chimeric ...
