| seroprevalence of actinobacillus (haemophilus) pleuropneumoniae serotype-1 infection in swine herds in quebec. | seroprevalence of actinobacillus (haemophilus) pleuropneumoniae serotype-1 infection was evaluated in pigs on 7 farms in quebec. commercial cross-bred herds a to g, ranging from 110 to 235 sows and infected with a pleuropneumoniae serotype-1 were selected. five pigs/litter were selected at random and were identified (group 1). blood samples were obtained from group-1 pigs at 2 to 4, 14, 28, 42, and 56 days of age. blood also was obtained from group-1 pigs remaining in the postweaning unit at 70 ... | 1990 | 2298655 |
| development of a new serological test for serotyping haemophilus parasuis isolates and determination of their prevalence in north america. | haemophilus parasuis causes polyserositis in swine. fifteen serovars have been characterized by immunodiffusion test, but many field strains are not typeable. isolates (n = 300) of h. parasuis from animals in north america were serotyped by a new indirect hemagglutination test. the test was rapid and effective for serotyping of h. parasuis, and serovars 4, 5, 13, and 7 were the most prevalent serotypes. | 2004 | 14766867 |
| acute epiglottitis in children and adults: a large-scale incidence study. | with the introduction of an anti-haemophilus type b vaccine, a standard incidence rate for acute epiglottitis is needed to judge its efficacy. epiglottitis is thought to be more common in children than in adults, but this relation has never been clearly established. this article attempts to evaluate the incidence of this disease. a review of the literature regarding the incidence is correlated to new data from the 1981 census of canada and the med-echo system of the province of quebec. it sugges ... | 1990 | 2126123 |
| acute epiglottitis - 25 years' experience in management, the montreal children's hospital. | acute epiglottitis is the most treacherous inflammatory process that can affect the respiratory tract. it can be a cause of sudden death in children. the clinical features of this entity are reviewed and our experience with its management at the montreal children's hospital during the past 25 years is presented. the establishment of a "secure" airway by tracheostomy and in recent years, by nasotracheal intubation has decreased to practically nil the mortality of children who arrive alive at this ... | 1977 | 604513 |
| [why are some children incompletely vaccinated at the age of 2?]. | a survey was conducted in the province of quebec to document the factors associated with an incomplete immunization status among 2-year-old children. | 2003 | 12790498 |
| acute epiglottitis in children: results of a large-scale anti-haemophilus type b immunization program. | the incidence of acute epiglottitis in children is declining in the province of quebec, canada. in 1988, a prp-d anti-haemophilus type b vaccine was introduced into the routine vaccination schedule of 18-month-old children. a substantial reduction in the occurrence of acute epiglottitis was perceived by clinicians. since 1992, improved new vaccines (prp-t, hboc, prp-ompc), given to 2-month-old infants, have been expected to increase the efficacy of the immunization program. the impact of the imm ... | 1995 | 7602678 |

| epidemiology of haemophilus somnus infection in dairy cattle in quebec. | serological studies on haemophilus somnus infection were carried out on 1795 cattle from 231 dairy herds in the province of quebec. an epidemiological investigation was done in each of the dairy operations. seroreactivity rate and mean log2 titer for all the sera were 55.4% and 4.1620 respectively. cattle from eastern regions of quebec demonstrated the lowest prevalence of h. somnus agglutinins. the percentage of seroreactor animals was 60.3 in herds of 100 cattle or more in comparison to 53.2 i ... | 1983 | 6667432 |
| haemophilus somnus: a comparison among three serological tests and a serological survey in beef and dairy cattle. | serological tests for the detection of antibodies against haemophilus somnus were carried out in herds of beef and dairy cattle using three different techniques: agglutination, complement fixation and counterimmunoelectrophoresis. the agglutination test appeared to detect more seroreactors than the complement fixation and counterimmunoelectrophoresis tests. results of the three tests indicated that there were more positive reactors in beef cattle and dairy cattle from infected herds than in dair ... | 1983 | 6640414 |

| 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 |

| 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 |
