haemophilus influenzae meningitis in manitoba and the keewatin district, nwt: potential for mass vaccination. | a community-based surveillance study of all central nervous system infections was carried out in manitoba and the keewatin district, nwt, between apr. 1, 1981, and mar. 31, 1984. there were 201 cases of bacterial meningitis in manitoba over the study period, 81 (40%) caused by haemophilus influenzae; all but one isolate tested were type b (hib). there were nine cases of h. influenzae meningitis in the keewatin district. the overall annual incidence rate of h. influenzae meningitis in manitoba wa ... | 1988 | 3262404 |
meningitis in the central arctic: a 4-year experience. | there were 37 cases of meningitis during a 4-year period among the native and white populations served by the churchill health centre in northern manitoba, an annual incidence of 128 per 100 000 in the overall population and of 202 per 100 000 among the inuit. bacterial meningitis predominated; neisseria meningitidis and haemophilus influenzae each accounted for one third of the cases. there were five deaths, and 14 of the survivors had severe sequelae. therefore, although the doctors and nurses ... | 1981 | 7214288 |
invasive haemophilus influenzae in manitoba, canada, in the postvaccination era. | fifty-two haemophilus influenzae isolates from patients with invasive disease in the province of manitoba, canada, were examined for serotype, biotype, genotype, and antibiotic susceptibility. half of the 52 isolates were found to be serotype a, and 38.5% (20 isolates) were found to be nonserotypeable (nst). there were only three serotype b strains and one each for serotypes c, d, and f. all 26 serotype a isolates belonged to biotype ii and demonstrated identical or highly similar dna fingerprin ... | 2006 | 16597886 |

characterization of invasive haemophilus influenzae disease in manitoba, canada, 2000-2006: invasive disease due to non-type b strains. | in addition to the proportional increase in cases of non-type b haemophilus influenzae disease in the post-h. influenzae type b vaccine era, the incidence of invasive h. influenzae disease was found to be approaching the rates of h. influenzae type b disease that were documented in the prevaccine period. fifty-six percent of invasive disease now occurs in individuals aged >10 years. | 2007 | 17516405 |
population genetics and antibiotic susceptibility of invasive haemophilus influenzae in manitoba, canada, from 2000 to 2006. | one hundred and twenty-two isolates of haemophilus influenzae causing invasive disease were collected in manitoba, canada, from 2000 to 2006 and examined for serotype, biotype, sequence type (st) by multilocus sequence typing and antibiotic susceptibility. nonserotypeable (nst) isolates accounted for over half of the isolates collected (69 isolates, 56.6%). there were 36 serotype a, five serotype b, two serotype c, one serotype d, four serotype e and five serotype f isolates collected. the 69 ns ... | 2007 | 17922774 |
molecular characterization of four haemophilus influenzae serotype a strains isolated from patients in quebec, canada. | four epidemiologically unrelated haemophilus influenzae serotype a (hia) strains from patients in quebec, canada, were characterized and found to represent 3 distinct groups. one isolate, found to be biotype i and sequence type (st)-62 by multilocus sequence typing, was shown to possess the copper- and zinc-containing superoxide dismutase gene, sodc, and was suspected to belong to clonal division ii. the other 3 isolates were classified as clonal division i based on the absence of the sodc gene. ... | 2007 | 18026212 |
characterization of nontypeable haemophilus influenzae collected from respiratory infections and invasive disease cases in manitoba, canada. | with the introduction of the haemophilus influenzae serotype b (hib) vaccine, invasive hib disease has decreased substantially, but nontypeable h. influenzae (nt hi) disease appears to be increasing. in order to understand the origin of nt hi strains and their relationship with serotypeable strains, we analysed 125 nt hi isolates collected from individual patients with either invasive disease (70 isolates) or respiratory tract infections (55 isolates). serotype-specific and capsular transport ge ... | 2010 | 20041949 |
the international circumpolar surveillance interlaboratory quality control program for serotyping haemophilus influenzae and serogrouping neisseria meningitidis, 2005 - 2009. | the international circumpolar surveillance (ics) program was initiated in 1999 to conduct population-based surveillance for invasive pneumococcal disease in select regions of the arctic. the program expanded to include surveillance of invasive diseases caused by n. meningitidis and h. influenzae. an interlaboratory quality control (qc) program to monitor laboratory proficiencies in the serogrouping of n. meningitidis and serotyping of h. influenzae was co-developed by the arctic investigations p ... | 2011 | 22170933 |
