A total of 100 and 97% of Haemophilus influenzae type b strains from major infections were susceptible, respectively, to levels of rifampin and sulfisoxazole attainable in saliva. It is theoretically feasible to eliminate Haemophilus influenzae from the nasopharynx with these drugs.

We analyzed national Haemophilus influenzae (Hi) surveillance data from 1994 and 1995 to describe the epidemiology of Hi invasive disease among persons of all ages. Serotype data were available for 376 (56%) of 669 reported Hi cases among children aged 4 years or younger; 184 (49%) were H. influenzae type b (Hib). Among children aged 4 or younger, incidence (per 100,000) of all Hi invasive dise...

Surveillance for Haemophilus influenzae meningitis cases was performed in Salvador, Brazil, before and after introduction of H. influenzae type b (Hib) immunization. The incidence of Hib meningitis decreased 69% during the 1-year period after initiation of Hib immunization (from 2.62 to 0.81 cases/100,000 person-years; P<.001). In contrast, the incidence for H. influenzae type a meningitis incr...

Although systemic infections caused by Haemophilus influenzae type b occur worldwide, detailed epidemiologic data are available in but a few countries. The public health impact of morbidity, mortality, and serious sequelae from disease caused by H influenzae type b has stimulated the search for control strategies. In the United States now, active immunoprophylaxis is largely favored over treatm...

such as sepsis and meningitis, has declined substantially since the introduction of the H. influenzae serotype b vaccine. However, the H. influenzae type b vaccine fails to protect against nontypeable H. influenzae strains, which have become increasingly frequent causes of invasive disease, especially among children and the elderly. We summarize recent literature supporting the emergence of inv...

  Background and Objective: Bacterial meningitis is an important cause of mortality and long-term neural morbidity. Immediate diagnosis and treatment are necessary in appropriate time. This study was designed in Afzalipour Hospital in Kerman to evaluate meningitis causes, frequency and CSF laboratory changes. Patients and Methods: In this retrograde descriptive study from September 2003 to Se...

A mouse model system was employed to investigate the temporal pattern of pulmonary clearance of Haemophilus influenzae and to evaluate the effect of the type b polysaccharide capsule on this clearance pattern. The lungs of BALB/c mice were inoculated with boluses of several different H. influenzae strains via an endobronchial catheter. A fully encapsulated H. influenzae type b strain multiplied...
