Bacterial meningitis remains a serious cause of morbidity and mortality in childhood, despite the availability of effective vaccines against Haemophilus influenzae type b (Hib) or Streptococcus pneumoniae. The purpose of this study was to analyze data on bacterial meningitis cases in Korea from 1996 through 2005. The information of all hospitalized bacteria-proven meningitis cases was obtained ...

Twenty clinical isolates of Haemophilus influenzae type b were used to determine the in vitro interactions of rifampin with ampicillin or chloramphenicol. Potential interactions of the drugs were evaluated by calculating the fractional inhibitory concentration index and fractional bactericidal concentration index for each strain after treatments with the drugs alone and in combination. There wa...

The reactivity of anti-pilus antibodies to native and denatured Haemophilus influenzae b (Hib) pili was studied using rabbit serum prepared against piliated H. influenzae b strain M43 (p+) and adsorbed with its non-piliated variant, strain M42 (p-). The specificity of the adsorbed serum for Hib pili was documented by immunogold electron microscopy and by immunoprecipitation, which revealed the ...

introduction : haemophilus influenzae is a gram-negative bacterium causing a variety of respiratory infections in developing countries, especially in children. nasopharynx carriers of h. influenzae are the prominent source and transitional vectors of invasive diseases. as very limited information on h. influenzae carriage rate in iran was available, an evaluation on prevalence of this bacterium...

The glpTQ operon of Haemophilus influenzae type b (Hib) and nontypeable H. influenzae (NTHi) strains is highly conserved, except for a 1.4-kb glpTQ intergenic region that was found in most Hib strains. The presence of this intergenic region results in divergent glpTQ transcriptional profiles for Hib and NTHi where Hib strains appear to have evolved an alternative promoter for glpQ expression. B...

The objective of the present study was to assess the economical impact of invasive Haemophilus influenzae type b infections in Slovenia, where the annual incidence of these infections is 16.4/100000 in children less than 5 years of age, and to compare it with the costs of a vaccination programme. The lifetime costs and benefits were estimated for the annual birth cohort of 18200 children. In th...

Possible route(s) by which encapsulated bacteria invade the blood from the nasopharynx include (i) the direct invasion of submucosal blood vessels and (ii) clearance via lymphatics to regional nodes followed by bloodstream invasion. These possibilities were investigated in rats after intranasal inoculation with 10(5) Haemophilus influenzae type b. Within 24 h of inoculation, 10 of 42 rats with ...

Haemophilus influenzae is a Gram-negative human pathogen that resides in the upper respiratory tract. Encapsulated H. influenzae type b (Hib) and type f (Hif) are the most common serotypes associated with invasive disease. H. influenzae displays various strategies to circumvent the host innate immune response, including the bactericidal effect of the complement system. In this study, we identif...
