campylobacter enteritis in british columbia--a 30 month study.		1985	4084888
serotyping of campylobacter jejuni isolated from sporadic cases and outbreaks in british columbia.	campylobacter jejuni from sporadic cases and outbreaks of gastroenteritis were serotyped on the basis of heat-extracted soluble thermostable antigens identified with the use of the passive hemagglutination technique. a total of 168 isolates were separated into 45 different types. the largest proportion of the isolates fell into three serotypes, each with 11 to 12.5% of the total number. three less frequently occurring serotypes each included approximately 5%, and the remaining 50% of the isolate ...	1982	7119100
where's the pump? associating sporadic enteric disease with drinking water using a geographic information system, in british columbia, canada, 1996-2005.	we investigated whether risk of sporadic enteric disease differs by drinking water source and type using surveillance data and a geographic information system. we performed a cross-sectional analysis, at the individual level, that compared reported cases of enteric disease with drinking water source (surface or ground water) and type (municipal or private). we mapped 814 cases of campylobacteriosis, cryptosporidiosis, giardiasis, salmonellosis and verotoxigenic escherichia coli infection, in a r ...	2009	19590137
the occurrence and sources of campylobacter spp., salmonella enterica and escherichia coli o157:h7 in the salmon river, british columbia, canada.	in this study, we wished to assess the prevalence and determine the sources of three zoonotic bacterial pathogens (salmonella, campylobacter, and escherichia coli o157:h7) in the salmon river watershed in southwestern british columbia. surface water, sewage, and animal faecal samples were collected from the watershed. selective bacterial culture and pcr techniques were used to isolate these three pathogens and indicator bacteria from these samples and characterize them. campylobacter was the mos ...	2010	20154400
campylobacteriosis outbreak associated with ingestion of mud during a mountain bike race.	one of the largest reported campylobacteriosis outbreaks in canada occurred in june 2007 in british columbia, associated with a mountain bike race that took place in muddy conditions. a retrospective cohort study was conducted and environmental samples were collected and tested. there were 537 racers included in the study and 225 racers (42%) reported diarrhoeal illness after the race. c. jejuni clinical isolates (n=14) were found to be identical by multi-locus sequence typing. although univaria ...	2010	20334726
knowledge and attitudes toward food safety and use of good production practices among canadian broiler chicken producers.	provincial broiler-chicken marketing boards in canada have recently implemented an on-farm food safety program called safe, safer, safest. the purpose of this study was to measure broiler chicken producers' attitudes toward the program and food safety topics and use of highly recommended good production practices (gpp). mailed and web-based questionnaires were administered to all producers registered in british columbia, ontario, and quebec in 2008. the response percentage was 33.2% (642 of 1,93 ...	2010	20615340
campylobacter spp. distribution in biofilms on different surfaces in an agricultural watershed (elk creek, british columbia): using biofilms to monitor for campylobacter.	despite its relevance to public health, presence and concentrations of campylobacter spp. in biofilms in natural aquatic environments has not been investigated. this study examined the occurrence of campylobacter spp. in biofilms on a variety of surfaces (river rock, slate rock, wood, lexan™, sandpaper, and sediment) and in water from december 2005 to december 2006 to find a substratum that facilitated campylobacters detection in natural aquatic environments. samples were collected at four sites ...	2011	22204983
