Examination of Neisseria meningitidis strains associated with endemic meningococcal disease demonstrated differences in the number of copies of a repetitive sequence. Characterization of a copy of this repetitive sequence present in B15 strains has revealed the presence of a novel insertion sequence (IS1106) located within a complex repetitive region(More)
Meningococcal disease is normally suspected on clinical grounds but confirmed by isolation of Neisseria meningitidis from blood or cerebrospinal fluid (CSF), or by detection of gram-negative diplococci in CSF. After parenteral antibiotics are started the isolation rate of meningococci from blood cultures drops from 50% to less than 5% and the chances of CSF(More)
The genetic relationships between various serotypes and serogroups of meningococcal strains were investigated by restriction fragment-length polymorphism (RFLP) analysis using a number of random DNA probes and a probe containing a truncated copy of the meningococcal insertion sequence IS1106. The data were used to estimate genetic distance between all pairs(More)
The continual emergence of bacterial resistance problems to current clinical drugs has brought a severe threat against human being's health; and the development of novel antimicrobial agents for selectively inhibiting the constantly evolved bacterial targets has also been continually promoted, with challenging processes like marathon race. FabH, which(More)
