| an outbreak of campylobacter enteritis associated with a community water supply. | in june 1987, an outbreak of acute enteritis occurred over a period of 2 weeks in a small rural community where the potable water supply is unfiltrated and unchlorinated. campylobacter jejuni was isolated from 6 patients. a case-control study performed in a local fiberglass shop where workers drink a lot of water, showed an association between the occurrence of enteritis and the consumption of 10 or more 8-ounce glasses of water per day (odds ratio = 6, p = 0.04). the attack rate of enteritis wa ... | 1990 | 2207948 |
| susceptibility of clinical isolates of campylobacter jejuni to twenty-five antimicrobial agents. | the in-vitro activity of 25 antimicrobial agents against 113 to 161 clinical isolates of campylobacter jejuni was tested by an agar dilution method. all strains were susceptible to the four aminoglycosides tested, to imipenem, chloramphenicol and norfloxacin. one strain (0.6%) was resistant to each of the following antibiotics: nalidixic acid, erythromycin and clindamycin. the frequency of tetracycline, metronidazole and cotrimoxazole resistance among our isolates was 14.5%, 56.4% and 96% respec ... | 1986 | 3493235 |
| antimicrobial resistance of clinical strains of campylobacter jejuni subsp. jejuni isolated from 1985 to 1997 in quebec, canada. | the antimicrobial resistance of 158 campylobacter jejuni strains isolated from humans in quebec, canada, from 1995 to 1997 was compared to the resistance of 47 and 86 strains of c. jejuni isolated in 1985 and 1986 and in 1992 and 1993, respectively. of the 291 c. jejuni strains tested, no strain was resistant to erythromycin. compared to the c. jejuni strains isolated in 1985 and 1986, the c. jejuni strains isolated in 1992 and 1993 were more resistant to tetracycline (40.7 versus 19.1%, respect ... | 1998 | 9687415 |
| comparison of smai-defined genotypes of campylobacter jejuni examined by kpni: a population-based study. | pulsed-field gel electrophoresis (pfge) was used to analyse 147 isolates collected in two regions of quebec province (estrie and montreal) between march 1998 and feb. 1999, to determine the utility of molecular strain typing for a population-based collection of campylobacter jejuni and to compare directly the discriminatory power of smai and kpni restriction digests. with a combination of epidemiological criteria including space and time plus molecular strain typing, 49% of isolates from estrie ... | 2001 | 11761192 |
| antimicrobial resistance of campylobacter jejuni subsp. jejuni strains isolated from humans in 1998 to 2001 in montréal, canada. | the rates of resistance of 51 to 72 human strains of campylobacter jejuni subsp. jejuni isolated annually from 1998 to 2001 in montréal, québec, canada, varied from 1 to 12% for erythromycin, 43 to 68% for tetracycline, and 10 to 47% for ciprofloxacin. in the last years of the study, there was a significant increase in the rate of resistance to ciprofloxacin (p = 0.00003) but not in the rate of resistance to erythromycin (p = 0.056) or tetracycline (p = 0.095) compared to the rate obtained in th ... | 2003 | 12760892 |
| cluster of erythromycin- and ciprofloxacin-resistant campylobacter jejuni subsp. jejuni from 1999 to 2001 in men who have sex with men, québec, canada. | from december 1999 to november 2001, a cluster of multidrug-resistant campylobacter jejuni subsp. jejuni enterocolitis was suspected within the male population of montreal. nine men, aged 26-40 years, presented with an erythromycin- and ciprofloxacin-resistant, tetracycline-susceptible c. jejuni enterocolitis. in march 1998 and february 2000, 2 additional men, aged 23 and 27 years, were infected with an erythromycin-resistant, ciprofloxacin and tetracycline-susceptible c. jejuni. all isolates we ... | 2003 | 12830417 |
| comparison of antimicrobial resistance of campylobacter jejuni isolated from humans, chickens, raw milk, and environmental water in québec. | this study compares the occurrence of antimicrobial resistance to erythromycin, ciprofloxacin, and tetracycline among 384 campylobacter jejuni isolates from humans (245), fresh whole retail chickens (56), raw milk (33), and environmental water (41) collected between 2000 and 2003 in québec, canada. resistance to ciprofloxacin was significantly more frequent in human isolates acquired abroad than in those acquired locally (50 versus 5.9%; p < 0.001); ciprofloxacin resistance was almost absent in ... | 2007 | 17388066 |
| multilocus sequence typing of campylobacter jejuni isolates from humans, chickens, raw milk, and environmental water in quebec, canada. | molecular strain typing is essential for deciphering the epidemiology of campylobacter jejuni infections. we applied two different methods, multilocus sequence typing (mlst) and analysis of the flaa short variable repeat (svr), to 289 isolates (163 human, 56 chicken, 34 raw milk, and 36 environmental water isolates) collected in the province of québec, canada, over 3 years; in addition, the analysis included the pulsed-field gel electrophoresis (pfge) typing results for a subset of 131 isolates ... | 2008 | 18701662 |
| thermotolerant coliforms are not a good surrogate for campylobacter spp. in environmental water. | this study aimed to assess the importance of quantitatively detecting campylobacter spp. in environmental surface water. the prevalence and the quantity of campylobacter spp., thermotolerant coliforms, and escherichia coli in 2,471 samples collected weekly, over a 2-year period, from 13 rivers and 12 streams in the eastern townships, québec, canada, were determined. overall, 1,071 (43%), 1,481 (60%), and 1,463 (59%) samples were positive for campylobacter spp., thermotolerant coliforms, and e. c ... | 2009 | 19734335 |
| microbiological quality of blue mussels (mytilus edulis) in nunavik, quebec: a pilot study. | this pilot study was aimed at documenting the presence of fecal indicators and enteric pathogens in blue mussels (mytilus edulis) from 6 communities in nunavik, quebec. one to four 2 kg samples of mussels were collected at low tide in each community. samples were investigated by enumeration methods for the fecal indicators enterococci, escherichia coli, f-specific coliphages, clostridium perfringens, and by molecular identification for the pathogens norovirus, salmonella spp., campylobacter jeju ... | 2010 | 21076488 |
| use of amplified-fragment length polymorphism to study the ecology of campylobacter jejuni in environmental water and to predict multi-locus sequence typing clonal complexes. | we determined the genetic variability among water isolates of campylobacter jejuni using aflp and mlst. across a highly diverse collection of isolates, aflp clusters did not correlate with mlst clonal complexes, suggesting that alfp is not reliable for deciphering population genetic relationships and may be problematic for larger epidemiologic analyses. | 2012 | 22267674 |
| presence and characterization of campylobacter jejuni in organically raised chickens in quebec. | the objective of this study was to estimate the presence of the important foodborne pathogen campylobacter jejuni in organically raised chickens in the province of quebec. the recovered isolates were further characterized for their antimicrobial resistance profile, autoagglutination property and chemotaxis. antimicrobial resistance was evaluated using agar dilution for: tetracycline, erythromycin, chloramphenicol, ciprofloxacin, gentamicin, nalidixic acid, clindamycin, ampicillin, azithromycin, ... | 2011 | 22468028 |
| detection and characterization of campylobacter spp. from 40 dairy cattle herds in quebec, canada. | dairy cattle are considered a campylobacter reservoir in the epidemiology of campylobacteriosis. currently, very little data on the prevalence of campylobacter in dairy herds are available in the province of quebec, canada. the objectives of this study were to evaluate the prevalence of campylobacter associated with management practices in 40 dairy cattle herds as well as to characterize the bacterial genetic diversity. fecal samples from 797 lactating cows of 40 dairy farms, water provided to a ... | 2014 | 24617502 |
