| 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 |
| antimicrobial susceptibility and serotypes of actinobacillus (haemophilus) pleuropneumoniae recovered from missouri swine. | the antimicrobial susceptibility of 73 actinobacillus (haemophilus) pleuropneumoniae isolates from swine in missouri was determined with a microdilution minimal inhibitory concentration test system. serotyping was accomplished by means of co-agglutination. serotype 1 (39/73) and serotype 5 (30/73) were commonly found, whereas serotype 7 (4/73) was infrequently encountered. most isolates (mic90) were found susceptible to ampicillin (amoxicillin), cephalothin, penicillin, erythromycin, gentamicin, ... | 1989 | 2488644 |
| postneonatal infant mortality in infants to a neonatal intensive care unit. | the postneonatal infant mortality (pnim) of 2,205 infants admitted to a neonatal intensive care unit from january 1971 to december 1974 was 44 in 1,000 infants who survived to age 28 days. this rate is approximately ten times that of the general population. congenital malformations (59%), infections (12%), sudden infant death syndrome (10%), and asphyxial brain damage (10%) were the most common causes of death. one third (26) of the infants remained in the hospital whereas two thirds (52) had be ... | 1978 | 358119 |
| haemophilus influenzae type b disease in an amish population: studies of the effects of genetic factors, immunization, and rifampin prophylaxis on the course of an outbreak. | in 1982, an outbreak of haemophilus influenzae type b disease occurred in a 379-member amish community. in an attempt to control the outbreak after the occurrence of the second case of disease, we investigated the combination of (1) rifampin chemoprophylaxis of all carriers of h influenzae type b and their household contacts from 1 month to 5 years of age and (2) h influenzae type b polysaccharide vaccine immunoprophylaxis of all community members 12 months of age and older. despite our interven ... | 1986 | 3485275 |
| differences in the immunogenicity of three haemophilus influenzae type b conjugate vaccines in infants. | to compare the immunogenicity of three haemophilus influenzae type b (hib) conjugate vaccines in infants residing in different geographic areas. | 1992 | 1640282 |
| etiology of septic arthritis in children: an update for the 1990s. | to establish the etiology of septic arthritis in children after implementation of hib immunization guidelines. | 1999 | 10069312 |
| changing antibiotic sensitivity patterns at a university hospital, 1992 through 1999. | the emergence of antibiotic-resistant organisms is of great concern in the medical community. antibiotic sensitivity patterns were studied at a large university hospital. | 2001 | 11440331 |
