A total of 42 strains of Haemophilus influenzae type b isolated from pediatric patients were sensitive in vitro to temocillin (90% minimal inhibitory concentration = 0.25 microgram/ml). No difference in mean minimal inhibitory concentration between beta-lactamase producer (0.25 microgram/ml) and nonproducer (0.23 microgram/ml) strains was found. Various dosages of ampicillin or temocillin for t...

Haemophilus influenzae type b is the leading cause of meningitis in children younger than 5 years of age in the United States. The incidence of infection with H influenzae type b in certain populations, such as Apache and Navajo Indians and Alaskan Eskimos, is 10 to 20 times higher than in the general US population. Another important feature of H influenzae type b infections in these population...

Haemophilus influenzae type b and nontypeable H. influenzae have been reported to bind human immunoglobulin D (IgD). IgD myeloma sera from five patients were tested for the ability of IgD to bind to H. influenzae. Serotype b strains bound human IgD in four of the five sera tested. IgD in the fifth serum bound strongly to type b strain MinnA but poorly to other type b strains. Additionally, IgD ...

PURPOSE OF REVIEW Intravenous dexamethasone (DXM) is used as adjuvant medication in bacterial meningitis of childhood, although no single study has proven its efficacy against death, severe neurological sequelae, or hearing impairment. Meta-analyses do not facilitate interpretation, because they combine profoundly dissimilar populations and neglect the child's presenting condition. Important ne...

OBJECTIVE: During the second half of 1996, the municipalities of Londrina and Curitiba (State of Paraná, Brazil) included Haemophilus influenzae type b (Hib) vaccine into their routine vaccination regimen, approximately 30 months before its introduction into the National Immunization Program. The present study aimed at verifying the incidence of meningitis caused by Hib among children in Londri...

Invasive infections caused by non-type b encapsulated Haemophilus influenzae have increased in frequency in the last decade. This change prompted us to characterize the genetic relationships of 48 recently isolated invasive H. influenzae type a (Hia), e (Hie), and f (Hif) strains by comparison of restriction digest patterns (RDPs). Recent Hia isolates exhibited moderate genetic diversity, with ...

Haemophilus influenzae may make any one of six chemically distinct capsular polysaccharides, but only strains of capsular serotype b commonly cause systemic infection (e.g., meningitis) in humans. Molecular cloning of DNA was used to investigate the expression of type b capsule and its association with H. influenzae virulence. A virulent H. influenzae type b strain was used to construct a lambd...
