| escherichia coli strains isolated from diarrheic piglets in the province of quebec. | during 1972 to 1974, 112 escherichia coli strains isolated from diarrheic piglets were recieved from different parts of the province of quebec, canada. fifty-six strains elicited a positive gut loop response in three week old piglets and were then considered as moon's class 1 enteropathogens, while four of the 56 remaining strains reacted only in ten day old piglets and were classified as class 2 enteropathogens. forty-eight strains produced both a heat-labile and a heat-stable enterotoxin, whil ... | 1976 | 793691 |
| serological characterization of actinobacillus pleuropneumoniae strains isolated from pigs in quebec. | a total of 3306 isolates of a. pleuropneumoniae originating from lung tissues of pigs that died of acute pleuropneumonia and 140 isolates recovered from tonsils or nasal cavities of apparently healthy pigs from chronically infected herds were serotyped. various serotyping methods, such as slide agglutination, tube agglutination, ring precipitation, coagglutination, immunodiffusion, indirect hemagglutination and counterimmunoelectrophoresis either alone or in combination were used. the techniques ... | 1992 | 1441197 |
| serotyping of canadian isolates of treponema hyodysenteriae and description of two new serotypes. | a total of 30 isolates of treponema hyodysenteriae collected in the saint-hyacinthe (quebec, canada) area were serotyped by agar gel double immunodiffusion by using extracted lipopolysaccharide and hyperimmune rabbit antisera. only 17% (5 of 30) of the isolates were typed with antisera specific for each of the seven known serotypes of t. hyodysenteriae. antisera raised against 11 untypeable local isolates were then produced and tested against each lipopolysaccharide extract. results showed two s ... | 1991 | 1757550 |
| coronaviruses associated with outbreaks of transmissible enteritis of turkeys in quebec: hemagglutination properties and cell cultivation. | coronaviruses were observed by electron microscopy in the intestinal contents of turkeys in quebec flocks where repeated outbreaks of enteritis occurred. three isolates could be serially propagated in turkey embryos inoculated by the amniotic route with clarified intestinal contents. purification and concentration of viral particles contained in intestinal contents of infected embryos were achieved by precipitation with polyethylene glycol and ultracentrifugation on sucrose density gradients. th ... | 1986 | 3015116 |
| genomic variations and antigenic relationships among cytopathic rotavirus strains isolated in quebec dairy herds. | twelve isolates of bovine rotavirus, originating from eight dairy herds in quebec known to have frequent epizootics of diarrhea in young calves in the last five years, were successfully propagated in cell cultures. the 12 isolates produced clear-cut plaques in bsc-1 cells and, except for one isolate, agglutinated human group "o" erythrocytes to an higher titer than bovine erythrocytes. antisera to each isolate were produced in rabbits and used to study their antigenic relationships. all the isol ... | 1986 | 3017524 |

| activity of california encephalitis group viruses in entrelacs (province of quebec, canada). | during the summer of 1979, indicator rabbits were placed in three sites in entrelacs (laurentian area, province of quebec) and mosquitoes were collected in order to monitor arbovirus activity in the area. eight seroconversions to california encephalitis (ce) group viruses were detected in rabbits during june, july, and august. twenty-five strains identified as members of the ce group were isolated: 3 were obtained from viremic rabbit sera, 1 from adult aedes communis reared in the laboratory fro ... | 1982 | 6126267 |
| porcine reproductive and respiratory syndrome virus: morphological, biochemical and serological characteristics of quebec isolates associated with acute and chronic outbreaks of porcine reproductive and respiratory syndrome. | cytolytic and noncytolytic strains of the porcine reproductive and respiratory syndrome virus (prrsv) were isolated in primary cultures of porcine alveolar macrophages (pam) from lung homogenates of stillborn fetuses or blood samples of dyspneic piglets collected from quebec pig farms having experienced acute or chronic outbreaks of prrs. serological identification of the virus was confirmed by indirect immunofluorescence and indirect protein a-gold immunoelectron microscopy using reference anti ... | 1994 | 8143254 |

| prevalence of o1/k1- and o2/k3-reactive actinobacillus suis in healthy and diseased swine. | a cell surface antigen-typing system was devised for the swine pathogen actinobacillus suis and used to examine the prevalence of different lipopolysaccharide (o) types in healthy and diseased pigs. the strains examined in this study were isolated from a variety of locations in canada and from kansas. lipopolysaccharide preparations of 151 isolates of a. suis were characterized by immunoblotting using polyclonal antisera generated to strains so4 (o1/k1), h89-1173 (o2/k3), and vsb 3714, a rough s ... | 2000 | 11015398 |

| tularemia, plague, yersiniosis, and tyzzer's disease in wild rodents and lagomorphs in canada: a review. | information related to infection of wild rodents or lagomorphs in canada by francisella tularensis, yersinia pestis, other yersinia spp., and clostridium piliforme was searched for this study. reports on tularemia in humans linked to these species came from diagnostic databases, literature, wildlife health specialists, and public health agencies. tularemia has been diagnosed in 8 species of wild rodent and 2 species in the genus lepus in canada. tularemia occurred in wild animals, or in humans a ... | 2009 | 20190973 |
| Widespread dispersal of Borrelia burgdorferi-infected ticks collected from songbirds across Canada. | Abstract Millions of Lyme disease vector ticks are dispersed annually by songbirds across Canada, but often overlooked as the source of infection. For clarity on vector distribution, we sampled 481 ticks (12 species and 3 undetermined ticks) from 211 songbirds (42 species/subspecies) nationwide. Using PCR, 52 (29.5%) of 176 Ixodes ticks tested were positive for the Lyme disease spirochete, Borrelia burgdorferi s.l. Immature blacklegged ticks, Ixodes scapularis, collected from infested songbird ... | 2011 | 21864130 |
