Chlamydia trachomatis (Ct) is the leading cause of sexually transmitted diseases worldwide. There is no safe and effective vaccine to control the spread of Ct. In development of Ct vaccine, selection of appropriate candidate antigens and an effective delivery system may be the main challenges. Multi-epitope of major outer membrane protein (MOMPm) is the most suitable candidate for a Ct vaccine,...
Background: Pasteurella multocida is a Gram-negative, non-motile, non-spore forming, and aerobic/anaerobic cocobacillus known as the causative agent of human and animal diseases. Humans can often be affected by cat scratch or bite, which may lead to soft tissue infections and in rare cases to bacteremia and septicemia. Commercial vaccines against this agent include inactivated, live attenuated,...
Background: Mycobacterium tuberculosis is the causative agent of tuberculosis (TB). Bacille Calmette-Guerin (BCG) vaccine, is not effective in adults, therefore, many efforts have been made to produce an effective adult TB vaccine. The aim of this study was to develop a new tuberculosis DNA vaccine candidate encoding a recombinant HspX-PPE44-EsxV fusion antigen of M. tuberculosis. Methods: ...
As the impact of dengue expands, a safe and effective vaccine will benefit the world greatly. Recent progress and novel approaches have advanced the field, but many challenges and unanswered questions remain for dengue vaccine developers. The most advanced dengue vaccine candidate, a chimeric yellow fever dengue (CYD) tetravalent vaccine, was the first dengue vaccine tested in a field efficacy ...
Introduction: The development of an effective vaccine against Hepatitis C virus (HCV) is still a target of intensive vaccine research. The HCV envelope proteins E1 and E2 which can induce broadly neutralizing antibodies are the major candidate for this purpose. Different types of expression systems have been used to express these glycoproteins. In this study, an expression system using Pichia p...
Memory formation is the most important aspect of a vaccine which can guarantee long-lasting immunity and protection. The main aim of the present study was to evaluate the memory immune responses after immunization with a mini vaccine. Mice were immunized with human immunodeficiency virus-1 P24-Nef fusion peptide and then cellular and humoral immune responses were evaluated. In order to determin...
background: staphylococcus aureus (s. aureus) is a major nosocomial pathogen and the infection with this organism in human is increasing due to the spread of antibiotic resistant strains. one of the resistance mechanisms of s. aureus comprises modification in binding proteins to penicillin. vaccine strategy may be useful in controlling the infections induced by this organism. this study aimed a...
