OBJECTIVE New vaccines that offer protection against otitis media caused by nontypeable Haemophilus influenzae and by Moraxella catarrhalis are under development. However, the potential health benefits and economic effects of such candidate vaccines have not been systematically assessed. METHODS We created a computerized model to compare the projected benefits and costs of (1) the currently a...

BACKGROUND The 1.83 Megabase (Mb) sequence of the Haemophilus influenzae chromosome, the first completed genome sequence of a cellular life form, has been recently reported. Approximately 75 % of the 4.7 Mb genome sequence of Escherichia coli is also available. The life styles of the two bacteria are very different - H. influenzae is an obligate parasite that lives in human upper respiratory mu...

OBJECTIVES To determine the antimicrobial susceptibility of Haemophilus influenzae, Moraxella catarrhalis and Streptococcus pneumoniae causing community-acquired lower respiratory tract infection in the UK during 2002/2003 and to compare susceptibilities determined locally by disc diffusion with agar dilution MICs determined at a central laboratory. METHODS H. influenzae, M. catarrhalis and S...

Acute respiratory infections in children aged less than 5 years in the Eastern Highlands of Papua New Guinea were investigated bacteriologically for 10 years from November 1978. Haemophilus influenzae and Streptococcus pneumoniae were responsible for 73% of all bacteria cultured from lung aspirate (83 samples), 85.5% from blood (1024 samples) and 92% from cerebrospinal fluid (155 samples). None...

Introduction. This is the first case report of septic abortion due to β-lactamase-negative ampicillin-resistant (BLNAR) non-typeable Haemophilus influenzae infection. In Japan, BLNAR H. influenzae is widespread and has become a clinical concern, especially in paediatrics and otolaryngology, but H. influenzae has not been previously recognized as a causative agent of obstetric or gynaecological ...

Changes in nasopharyngeal flora were investigated in children with acute otitis media and with acute exacerbations of chronic sinusitis in whom antibiotic therapy of relatively long duration was required until substantial improvement in clinical findings was achieved. 1. The antibiotics used were two cephalosporins, i.e., cefaclor (CCL) and cefixime (CFIX), administered to 18 patients each for ...

The attachment of isogenic fimbriated and nonfimbriated Haemophilus influenzae type b variants to human cells was studied by using a radioactive assay and an indirect immunofluorescent assay. As described previously, fimbriated H. influenzae variants adhered to a greater extent than nonfimbriated variants to human buccal epithelial cells (2.1 and 0.29 bacteria per cell, respectively, as determi...

BACKGROUND Haemophilus influenzae infections have declined dramatically in the United States since implementation of the conjugate vaccine. However, in countries where widespread immunization is not routine, H influenzae remains a significant cause of morbidity and mortality. We report a case of a previously unvaccinated immigrant with confirmed H influenzae sepsis and placental abruption leadi...

PCR was used to detect Haemophilus influenzae in samples of nasopharyngeal secretion and middle ear effusion (MEE). Nasopharyngeal secretions were collected from 102 patients with otitis media with effusion and from 111 healthy subjects. Eighty samples of MEE were collected from patients with otitis media with effusion. A pair of primers was designed to amplify a DNA segment of the gene encodin...

Haemophilus influenzae, a Gram-negative bacterium and a member of the family Pasteurellaceae, causes chronic bronchitis, bacteremia, meningitis, etc. The H. influenzae is the first organism whose genome was completely sequenced and annotated. Here, we have extensively analyzed the genome of H. influenzae using available proteins structure and function analysis tools. The objective of this analy...
