Latest Patents

Mark Sydenham holds a patent for "Vaccines containing attenuated bacteria." This invention relates to a vaccine comprising a bacterium that has been attenuated by a non-reverting mutation in a gene encoding a protein that promotes the folding of extracytoplasmic proteins. The mutations were identified as useful in vaccines from a bank of randomly inserted transposon mutants, where attenuation was determined by a reduction in virulence in a mouse model of infection. The site-directed mutation of the gene results in a strain that shows at least 4 logs of attenuation when delivered both orally and intravenously. Animals vaccinated with this strain are protected against subsequent challenges with the parent wild-type strain. Additionally, heterologous antigens, such as the non-toxic and protective binding domain from tetanus toxin, fragment C, can be delivered via the mucosal immune system using these strains of bacteria. This results in the induction of a fully protective immune response to subsequent challenges with native tetanus toxin.
