Between July 1993 and June 1996, there were 412 cases of invasive Haemophilus influenzae type b (Hib) disease reported to the Hib Case Surveillance Scheme, 71% in children under the age of five years. Meningitis was the most frequent illness reported, followed by epiglottitis, septicaemia and pneumonia. There were 18 deaths. Thirty-four cases were classified as vaccine failures. The number of v...

BACKGROUND The completeness of a compulsory reporting system of systemic Haemophilus influenzae infections in children in Germany is studied by means of cross-linking registry data from three sources and applying capture-recapture methods. METHODS Cases were collected for the years 2001-05 by three national data sources: a passive administration registry (SurvNet@RKI), an active hospital surv...

In the post-Haemophilus influenzae type b (Hib) vaccine era that began in the 1980's, H. influenzae type a (Hia) emerged as a prominent cause of invasive disease in North American Aboriginal populations. To test whether a lack of naturally acquired antibodies may underlie increased rates of invasive Hia disease, we compared serum bactericidal activity against Hia and Hib and IgG and IgM against...

Streptomycin resistance of a high degree has been induced in sensitive populations of Hemophilus influenzae and Hemophilus parainfluenzae by desoxyribonucleic acids (DNA's) derived from streptomycin (SM)-resistant cells of at least one heterologous species of Hemophilus. The specificity of the DNA which controls SM resistance has been studied within and among species of Hemophilus by comparing,...

The restriction enzymes Hind from Hemophilus influenzae and Hae,,, from Hemophilus aegyptius cleave bacteriophage S13 replicative form (RF) DNA into 13 and 10 specific fragments, respectively. The sizes of these fragments were estimated by gel efectrophoresis, electron microscopy, and pyrimidine isostich analysis. The Hind and Hae,,, fragments were ordered relative to each other by cross digest...

Because the epidemiology of pneumonia is changing, we performed an updated, population-based analysis of hospitalization and case-fatality rates for pneumonia patients in the United States. From 2002 to 2011, hospitalization rates decreased significantly for pneumonia caused by pneumococcus and Haemophilus influenzae but increased significantly for Pseudomonas spp., Staphylococcus aureus, and i...

Respiratory tract infections are one of the most important among military personals, worldwide. The present study aimed to survey prevalence bacterial and viral main etiological agents causing respiratory personnel in Iran. A cross-sectional was performed from November 2020 March 2021. Nasopharyngeal swabs were taken patients, with infection symptoms. Detection coronavirus disease 2019 (COVID-1...

This study conducted at the Research Institute for Tropical Medicine from April 1990 to December 1992, identified the etiology of acute lower respiratory tract infection (ALRI) in 119 (36.9%) of 317 hospitalized children < 5 years of age. A higher proportion of respiratory viruses (27.2%) than bacterial agents (10.7%) were identified. Viral agents (adenovirus, RSV, parainfluenza 3, influenza A ...

Community-acquired pneumonia is a common disease and a frequent cause of morbidity and mortality worldwide. Haemophilus influenzae is a leading cause of CAP. The current study was conducted to determine the serotype distribution and antimicrobial susceptibility patterns of Haemophilus influenzae isolated from unvaccinated adult patients with CAP at Assiut University Hospitals. Materials and Met...
