Recombinant Bacillus subtilis expressing the Clostridium perfringens alpha toxoid is a candidate orally delivered vaccine against necrotic enteritis.
Recombinant Bacillus subtilis endospores have been used to vaccinate against tetanus and anthrax. In this work, we have developed spores that could be used to vaccinate against Clostridium perfringens alpha toxin and that could be used to protect against gas gangrene in humans and necrotic enteritis in poultry. The primary active agent in both cases is alpha toxin. A carboxy-terminal segment of...
متن کاملCloning of the Gene Encoding M2e of Influenza Virus in B. subtilis
Background and Aims: The ectodomain of matrix protein of influenza virus is a weak immunogen that is highly conserved among all subtypes of influenza A virus. Tandem repeats of these genes along with linker were used to enhance immunogenicity of M2e protein and so it can be served as a universal vaccine in both humans and livestock. Materials and Methods: In this study, the sequences of extra-d...
متن کاملPotential recombinant vaccine against influenza A virus based on M2e displayed on nodaviral capsid nanoparticles
Influenza A virus poses a major threat to human health, causing outbreaks from time to time. Currently available vaccines employ inactivated viruses of different strains to provide protection against influenza virus infection. However, high mutation rates of influenza virus hemagglutinin (H) and neuraminidase (N) glycoproteins give rise to vaccine escape mutants. Thus, an effective vaccine prov...
متن کاملPresenting Influenza A M2e Antigen on Recombinant Spores of Bacillus subtilis
Effective vaccination against influenza virus infection is a serious problem mainly due to antigenic variability of the virus. Among many of investigated antigens, the extracellular domain of the M2 protein (M2e) features high homology in all strains of influenza A viruses and antibodies against M2e and is protective in animal models; this makes it a potential candidate for generation of a univ...
متن کاملImmunopotentiation of Trivalent Influenza Vaccine When Given with VAX102, a Recombinant Influenza M2e Vaccine Fused to the TLR5 Ligand Flagellin
BACKGROUND Currently controversy exists about the immunogenicity of seasonal trivalent influenza vaccine in certain populations, especially the elderly. STF2.4×M2e (VAX102) is a recombinant fusion protein that links four copies of the ectodomain of influenza virus matrix protein 2 (M2e) antigen to Salmonella typhimurium flagellin, a TLR5 ligand. The objectives of this study were to assess the f...
