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.

今年在这个项目上没有完成任何工作。 针对B组脑膜炎球菌性脑膜炎的疫苗发育变得复杂，它的胶囊多糖（PSA）是一种2-8连锁的聚硅酸，与大肠杆菌K1囊囊多糖的表面糖相同，尤其是在发育过程中，尤其是宿主结构。尽管有效的抗生素和支持疗法，但全身感染的死亡率和发病率，尤其是由B组脑膜炎球菌和大肠杆菌K1引起的脑膜炎，仍然令人难以接受。 B组脑膜炎球菌（GBM）继续引起世界各地的流行病和暴发，大肠杆菌K1是新生儿脑膜炎和肾脏感染的主要原因。这项研究的目的是检查PSA抗体与自身免疫性疾病之间关联的证据或缺乏证据。
