The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is still surging across the globe and has affected serious problems for both health global economy; therefore, development of a vaccine with good efficacy becomes must. To tackle pandemic, numerous sectors academia, industry, government collaborate to develop investigate poten...

Viral haemorrhagic septicaemia (VHS) is a fish rhabdovirus infection of world-wide importance. Control policies have been established but the disease still causes heavy losses in fish farming. The development of a recombinant subunit vaccine was initiated to produce a safe and effective vaccine to protect fish against VHS. The VHS virus (VHSV) glycoprotein, which induces neutralizing antibodies...

tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. fragment c (52 kd) of this toxin is responsible for binding to the neuronal membrane. for this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. presently, w...

colonization of nontypeable haemophilus influenzae (nthi) in nasopharynx causes respiratory tract disease. in 80% of clinical isolates, hmw proteins are the major adhesions and induce protective antibodies in the hosts. therefore, it can be used as a vaccine candidate. the aim of this study is designing and cloning of the conserved regions of nthi hmw1 core binding domain.in this study, the sta...

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...

background: recombinant vaccine technology is one of the most developed means in controlling infectious diseases. however, an effective vaccine against shigella is still missing. objective: to evaluate recombinant ipac protein of shigella as a vaccine candidate. methods: in this study we cloned ipac gene into an expression vector in prokaryotic system. the protein expression was evaluated by sd...
