An experimental vaccine for sepsis, composed of detoxified Escherichia coli J5 lipopolysaccharide (LPS) complexed with the outer membrane protein (OMP) of Neisseria meningitidis group B, induces anti-core glycolipid antibody and has been tested in pilot studies in human volunteers. ⋯ These results indicate that the detoxified LPS-J5/OMP vaccine induces high levels of antibody against the core glycolipid of LPS and functions in vivo to promote clearance of gram-negative bacteria and improve the outcome of experimental polymicrobial intra-abdominal sepsis.

Rubella and congenital rubella syndrome (CRS) continue to be important health problems in many countries. In June 2004, the World Health Organization Steering Committee on Research Related to Measles and Rubella Vaccines and Vaccination met to evaluate data from research and operational activities and to identify critical scientific issues and gaps in knowledge that need to be addressed to improve the global control of rubella and CRS. Information about surveillance for rubella, natural and vaccine-induced immunity to rubella, laboratory diagnosis, the molecular epidemiological profile of rubella virus, and mathematical modeling to assess the burden of CRS and the impact of rubella vaccination was reviewed. This report summarizes the presentations and recommendations for future research.

On the basis of a polymerase chain reaction-restriction fragment-length polymorphism analysis of the 16S-23S ribosomal DNA intergenic spacer, clinical isolates of Borrelia burgdorferi can be classified into 3 genotypes designated as RST1, RST2, and RST3. RST1 strains are the most pathogenic, and RST3 strains are the least pathogenic. ⋯ The DRB1*0101 allele and the DRB1*0101-DQB1*0501 haplotype may be relevant to the development of infection with strains from the least invasive genotypes of B. burgdorferi.
