Neisseria meningitidis is a major cause of bacterial septicemia and meningitis. Sequence variation of surface-exposed proteins and cross-reactivity of the serogroup B capsular polysaccharide with human tissues have hampered efforts to develop a successful vaccine. To overcome these obstacles, the entire genome sequence of a virulent serogroup B strain(More)
Meningococcal disease is a serious medical condition that can prove fatal within hours in otherwise healthy individuals. Disease incidence is highest in infants, yet there is no broadly protective quadrivalent vaccine that covers this age group. A new investigational quadrivalent meningococcal glycoconjugate vaccine against meningococcal serogroups A, C,(More)
Tick-borne encephalitis (TBE) virus is one of the most important flavivirus infections of the central nervous system in Europe and Russia, with 12,000 estimated human cases per year. At present, epidemiology is extensively analyzed in many regions of Europe and Russia, with less activity in east and southeast Asia. For China, surveillance on TBE is not(More)
Procedures for diagnostics of cytomegalovirus infections include histopathology, cell culture, serology, and direct detection of viral antigens or nucleic acids within infected cells or tissues. In order to develop a new diagnostic reagent for viral antigen detection, we generated a mouse monoclonal antibody. This antibody was raised against a recombinant(More)
In order to test the biotechnological potential of the cellular slime mould Dictyostelium discoideum the cDNA coding for human antithrombin III was expressed in this microorganism. The 1392-bp antithrombin III cDNA was fused to the N-terminal coding part of the D. discoideum actin 6 gene. In constructs carrying this artificial N-terminal coding region only(More)
A new ELISA technique using Nunc CovaLink NH microtiter plates has been developed to measure anticapsular polysaccharide specific antibodies. Capsular polysaccharide (PS) of Haemophilus influenzae type b (PRP) and pneumococcal antigens types 3, 6, 8, 14, 19, 23 were immobilized on CovaLink NH. These are modified plates with secondary amino groups bound to(More)
After more than 60 years, the conventional production of influenza vaccines employing fertilized chicken eggs has reached its limits - both in terms of temporal flexibility and vaccine production volume. This problem is compounded by the fact that the pandemic-driven situation in 2009 has roughly doubled the overall vaccine demand. Modern cell culture(More)
Once considered a local health issue confined to certain regions in Russia and Central and Eastern Europe, tick-borne encephalitis (TBE) is now considered an international health concern, and the most important and widespread viral disease transmitted by ticks in Europe. The number of reported TBE cases continues to increase in many endemic regions, and new(More)
Neisseria meningitidis or meningococcus is divided into 12 distinct serogroups of which A, B, C, W, X, and Y are medically most important and cause health problems in different parts of the world. The epidemiology of N. meningitidis is unpredictable over time and across geographic regions. Globally, serogroup A has been prevalent in the African "meningitis(More)
Recombinant outer membrane proteins (Oprs) of Pseudomonas aeruginosa were expressed in Escherichia coli as glutathione S-transferase (GST)-linked fusion proteins. GST-linked Oprs F and I (GST-OprF190-350 [GST linked to OprF spanning amino acids 190 to 350] and GST-OprI21-83, respectively) and recombinant hybrid Oprs (GST-OprF190-342-OprI21-83 and(More)
