Vaccine development for Group B Neisseria meningitidis and Escherichia coli K1

今年这个项目没有完成任何工作。

No work was accomplished on this project this year. Vaccine development against group B meningococcal meningitis is complicated by its capsular polysaccharide (PSA), an a 2-8-linked poly-sialic acid that is identical to the surface saccharide of the E. coli K1 capsular polysaccharide and to host structures especially during development. Despite effective antibiotic and supportive therapy, the mortality and morbidity of systemic infections, especially of meningitis caused by group B meningococci and Escherichia coli K1, remain unacceptably high. Group B meningococci (GBM) continue to cause epidemics and outbreaks throughout the world and E. coli K1 is a major cause of neonatal meningitis and of kidney infections. The aim of this study is to examine evidence or the lack thereof of the association between PSA antibodies and autoimmune disease.
