| the increasing incidence of ampicillin-resistant haemophilus influenzae. a cause of otitis media. | middle ear exudate was obtained by myringotomy or aspiration from 625 suburban children, aged 1 month to 12 years, who had acute otitis media; bacterial pathogens were isolated from 71%. haemophilus species were isolated from 212 (29%), and streptococcus pneumoniae from 205 (28%). from 1975 to august 1977, the number of haemophilus isolates found to be resistant to ampicillin has appreciably increased. currently, 8% of all cases of acute otitis media in the washington, dc, area are due to h infl ... | 1978 | 22767 |

| occurrence of bacteremia in febrile children seen in a hospital outpatient department and private practice. | blood cultures were obtained during a one-year period from 147 febrile children seen in the hospital outpatient clinic (group 1), and 42 seen in a private practice office (group 2). although the two clinics were located in the same geographic area, they served different socioeconomic groups. bacteremia was detected in 12 (8.2%) of the children in group 1; the organisms recovered were streptococcus pneumoniae in nine and haemophilus influenzae in three. bacteremia was observed in two (4.8%) of th ... | 1984 | 6333075 |
| bacteraemia in hospitalized children. | the results of 3,037 blood cultures taken from hospitalized children during 1977 are reviewed, and 171 patients were considered to have bacteraemia whilst 67 were considered to have contaminants. streptococcus pneumoniae, haemophilus influenzae, staphylococcus aureus and streptococcus spp were found to be the most common organisms associated with 80% of the observed bacteraemias. h. influenzae and groups b and d streptococci were more often isolated in young children (less than 3 years). group d ... | 1984 | 6530961 |

| genes involved in haemophilus influenzae type b capsule expression are frequently amplified. | the genes involved in haemophilus influenzae type b capsule expression are present as a duplication of an approximately 18-kb dna segment (the cap b locus). it has been shown previously that recombination occurs between the two copies of the repeat, resulting in deletion of one copy and loss of capsule expression at frequencies of 0.1%-0.5%. the present study tested the hypothesis that the duplicated arrangement could serve as a template for further amplification of capsule gene sequences. south ... | 1993 | 8421169 |
| national, state and urban area vaccination coverage levels among children aged 19-35 months--united states, july 1994-june 1995. | the national immunization survey (nis) is an ongoing survey to provide estimates of vaccination coverage levels among children aged 19-35 months in the united states, all 50 states, and selected urban areas. cdc implemented nis in april 1994 as one element of the five-part childhood immunization initiative (cii), a national strategy to achieve and maintain high vaccination levels among children during the first 2 years of life. nis collects quarterly data from all 50 states, the district of colu ... | 1996 | 9132566 |
| surveillance of antimicrobial resistance in streptococcus pneumoniae, haemophilus influenzae, and moraxella catarrhalis in the united states in 1996-1997 respiratory season. the laboratory investigator group. | a u.s. surveillance study of antimicrobial resistance in respiratory tract pathogens in the respiratory season (1996-1997) is reported that included 11,368 isolates from 434 institutions in 45 states and the district of columbia. beta-lactamase was produced by 33.4% of haemophilus influenzae and 92.7% of moraxella catarrhalis. of the 9,190 streptococcus pneumoniae isolates tested, 33.5% were not susceptible to penicillin (mic > or = 0.12 microgram/ml), with 13.6% having high-level resistance (mi ... | 1997 | 9458982 |

| prevalence and predictors of immunization among inner-city infants: a birth cohort study. | although the proportion of us children who are appropriately immunized increased dramatically in the past decade, rates remain suboptimal among low-income, inner-city youth. timely initiation of immunization is an important predictor of immunization status later in childhood; however, prospective studies identifying predictors of initiation are lacking. | 2001 | 11533333 |
| a survey of beta-lactamase-producing haemophilus influenzae. an evaluation of 5750 isolates. | previous studies have reported that 15%-34% of haemophilus influenzae produce beta-lactamase. a surveillance program was developed by smithkline beecham clinical laboratories to determine the current percentage of beta-lactamase-producing h. influenzae from five selected geographic locations in the united states. in 1993, results of 5750 isolates from specimens submitted to five reference clinical laboratories were evaluated. data were collected from 29 states and the district of columbia. the p ... | 1995 | 7554806 |

| epidemiologic characteristics of infections caused by ampicillin-resistant hemophilus influenzae. | hrom february 1974 through may 1975, 58 isolates of ampicillin-resistant hemophilus influenzae from patients were submitted to the center for disease control from 23 states and the district of columbia. the epidemiologic characteristics of these widely scattered cases were strikingly similar to those of cases previously reported from individual communities or institutions. because of the nationwide distribution of resistant isolates and the adverse consequences of ineffective therapy, the use of ... | 1976 | 1085436 |
