| phylogenetic analysis of urease-positive thermophilic campylobacter (uptc) strains based on the molecular characterization of the flaa gene. | molecular cloning, nucleotide sequencing, and characterization of the flaa gene from additional isolates of urease-positive thermophilic campylobacter (uptc) were performed. these isolates were obtained from the natural environment in northern ireland (n = 9 from mussels) and in england (n = 1 from sea water). all isolates carried the shorter flaa gene, [open reading frames (orfs), 1,461 to 1,503 base pairs], without any internal termination codons, and did not carry any flaa pseudogenes. the up ... | 2011 | 21874596 |
| risk factors for the carriage of campylobacter upsaliensis by dogs in a community in cheshire. | samples of faeces were taken from 183 healthy pet dogs in a census-based, cross-sectional study in cheshire; culture methods were used to detect any campylobacter species and a direct pcr was used to detect campylobacter upsaliensis. forty-six of the dogs were positive for c upsaliensis by either culture or direct pcr, giving a prevalence of 25.1 per cent (95 per cent confidence interval [ci] 19.0 to 32.1 per cent). one sample was positive by culture for campylobacter jejuni (95 per cent ci 0.0 ... | 2009 | 19880860 |
| prevalence of campylobacter spp. in raw retail poultry on sale in northern ireland. | a year-long survey of fresh, retail poultry products on sale in northern ireland was undertaken to define the prevalence of campylobacter spp. by using protocols based on iso (standard) 10272-1:2006. incubation at 37 and 42 degrees c was undertaken to increase the diversity of isolates obtained. overall, 652 isolates were identified as campylobacter spp. by using pcr and amplified fragment length polymorphic typing. phenotyping wrongly identified 21% of isolates. prevalences of campylobacter fou ... | 2009 | 19777882 |
| molecular epidemiology and characterization of campylobacter spp. isolated from wild bird populations in northern england. | campylobacter infections have been reported at prevalences ranging from 2 to 50% in a range of wild bird species, although there have been few studies that have investigated the molecular epidemiology of campylobacter spp. consequently, whether wild birds are a source of infection in humans or domestic livestock or are mainly recipients of domestic animal strains and whether separate cycles of infection occur remain unknown. to address these questions, serial cross-sectional surveys of wild bird ... | 2009 | 19286781 |
| prevalence and genetic diversity of campylobacter spp. in environmental water samples from a 100-square-kilometer predominantly dairy farming area. | water samples were taken systematically from a 100-km2 area of mainly dairy farmland in northwestern england and examined for campylobacter spp. pulsed-field gel electrophoresis-restriction fragment length polymorphism (pfge-rflp) and flaa strain typing of campylobacter jejuni and campylobacter coli isolates were done. data on the water source and the adjacent environment were recorded and examined as explanatory variables. campylobacter spp. were isolated from 40.5% (n = 119) of the water sampl ... | 2005 | 15812015 |
| ciprofloxacin resistant campylobacter spp. in humans: an epidemiological and laboratory study. | from the end of april 1991 until the end of 1991, 2209 isolates of campylobacter spp. have been collected in plymouth phl of which 91 (4.1%) were resistant to ciprofloxacin. none of the 91 patients involved had taken a quinolone, but 30/91 (33%) had travelled abroad (16 to the iberian peninsula) in the three months preceding isolation of the ciprofloxacin-resistant campylobacter spp. in the case-control study 12/15 (80%) of the cases had recently consumed poultry as had 20/24 (83%) of controls w ... | 1996 | 8722540 |
