| bacterial meningitis in navojo indians. | an analysis of 219 confirmed cases of bacterial meningitis among navajo indians during a 5-year period, july 1, 1968, through june 30, 1973, revealed that 56 percent were caused by haemophilus influenzae, 26 percent by neisseria meningitidis, 6 percent by mycobacterium tuberculosis, and 6 percent by other organisms. the annual incidence of h. influenzae meningitis (17.7 per 100,000 persons) and that of pneumococcal meningitis (8.0 per 100,000) were much higher than the rates for these diseases r ... | 1976 | 824672 |
| epidemiology of rob beta-lactamase among ampicillin-resistant haemophilus influenzae isolates in the united states. | we surveyed 161 clinical isolates of ampicillin-resistant, beta-lactamase-producing isolates of haemophilus influenzae obtained between 1975 and 1985 to determine whether they produced tem-1 or rob beta-lactamase. plasmid dna was obtained from a rob-producing isolate, f990, and a plasmid (pbr322) known to encode tem-1. both plasmids were labeled with 32p and hybridized to whole cell dna obtained from the clinical isolates. all 161 isolates hybridized with one of the plasmid probes and could be c ... | 1988 | 3257784 |
| lack of relationship of community patterns of respiratory viral activity to systemic haemophilus influenzae disease in children. | the occurrence of epidemics of respiratory viral illness was monitored by virus isolations in a population of young children living in the greater nashville area over a 4-year period. epidemic disease due to influenza, respiratory syncytial virus and parainfluenza type 1 was present during discrete time blocks over this interval. occurrence of systemic haemophilus influenzae type b disease in the community was also documented by review of bacteriologic records of vanderbilt children's hospital o ... | 1982 | 7163030 |
| the reporting of communicable diseases: a controlled study of neisseria meningitidis and haemophilus influenzae infections. | surveillance systems for communicable diseases in the united states are primarily passive. we compared the passive reporting system for invasive disease caused by neisseria meningitidis and haemophilus influenzae with a concurrent, active laboratory-based system in the four metropolitan counties of tennessee. the passive reporting system identified approximately 50% of all cases that were identified by the active system and accurately reflected trends in disease occurrence during the study perio ... | 1995 | 7727666 |
| enhanced antibody response in venezuelan infants immunized with haemophilus influenzae type b-tetanus toxoid conjugate vaccine. | the safety and immunogenicity of primary immunization at 2, 4 and 6 months of age with haemophilus influenzae type b capsular polysaccharide conjugated to tetanus toxoid (prp-t; act-hib) were evaluated in infants in valencia, venezuela. in order better to assess reactions to prp-t, subjects received their initial prp-t vaccine a mean of 6.5 days after their initial diphtheria-tetanus-pertussis (dtp) vaccine. the prp-t vaccine was well tolerated. serum was obtained at ages 2 and 7 months (before ... | 1994 | 7970953 |
| no increased risk for invasive bacterial infection found following diphtheria-tetanus-pertussis immunization. | during the acellular pertussis vaccine trial in sweden, 4 children who were randomly assigned to receive the vaccine died of suspected or confirmed bacterial infections compared to 1 expected. there were no deaths in the placebo arm. this raised concern about the role of pertussis immunization in the development of serious infections. through linking computerized immunization records with an active surveillance system for serious bacterial infections in children, the authors studied a cohort of ... | 1992 | 1557243 |
| an outbreak of infections caused by non-typeable haemophilus influenzae in an extended care facility. | nosocomial outbreaks of infection due to non-typeable haemophilus influenzae (nthi) are rarely described. there are a few published reports that suggest that elderly patients with underlying pulmonary disease are at risk and that person-to-person spread is key to disease transmission. during the summer months of 2005, we documented an outbreak of nthi infections in a veterans affairs nursing home. thirteen patients developed conjunctivitis or lower respiratory infection involving a beta-lactamas ... | 2007 | 17379356 |
| statewide survey of the antimicrobial susceptibilities of haemophilus influenzae producing invasive disease in tennessee. | between october 1, 1980, and september 30, 1981, a prospective statewide study of haemophilus influenzae infections identified 220 culture-proved systemic infections. of these, 92% were caused by h. influenzae type b. antimicrobial susceptibility testing of the type b isolates showed that 17% were resistant to ampicillin, but virtually all were susceptible to chloramphenicol, trimethoprim-sulfamethoxazole, cefaclor and rifampin. ampicillin resistance is common in all parts of tennessee and chlor ... | 1983 | 6602329 |
| efficacy of haemophilus influenzae type b conjugate vaccines and persistence of disease in disadvantaged populations. the haemophilus influenzae study group. | the purpose of this study was to evaluate the effectiveness of haemophilus influenzae type b (hib) conjugate vaccines among children aged 2 to 18 months and to determine risk factors for invasive hib disease during a period of declining incidence (1991-1994). | 1999 | 10076486 |
