escherichia coli o157:h7, an emerging gastrointestinal pathogen. results of a one-year, prospective, population-based examine the incidence of escherichia coli o157:h7 enteric infections in the united states and to evaluate the vehicles of transmission for sporadic cases, we conducted a one-year, population-based study at a large health maintenance organization (hmo) in the puget sound area of washington state. all stool specimens submitted for culture to the hmo laboratory were screened for e coli o157:h7; the organism was identified in 25 (0.4%) of 6485 stool specimens. all patients with e coli o157:h7 ide ...19883286919
prevalence and antimicrobial resistance of thermophilic campylobacter spp. from cattle farms in washington state.the prevalence of thermophilic campylobacter spp. was investigated in cattle on washington state farms. a total of 350 thermophilic campylobacter isolates were isolated from 686 cattle sampled on 15 farms (eight dairies, two calf rearer farms, two feedlots, and three beef cow-calf ranches). isolate species were identified with a combination of phenotypic tests, hipo colony blot hybridization, and multiplex lpxa pcr. breakpoint resistance to four antimicrobials (ciprofloxacin, nalidixic acid, ery ...200515640184
dissemination of antimicrobial resistant strains of campylobacter coli and campylobacter jejuni among cattle in washington state and california.the purpose of this study was to investigate the genetic similarity of campylobacter jejuni and campylobacter coli with similar antimicrobial resistance phenotypes, isolated from cattle on different farms and at different times, in order to evaluate the possible existence of disseminated antimicrobial resistant clones. pfge after smai and kpni restriction identified 23 and 16 distinct pfge patterns among 29 c. jejuni and 66 c. coli isolates, respectively. in c. coli, 51 (77%) of the resistant is ...200717321701
tri-county comprehensive assessment of risk factors for sporadic reportable bacterial enteric infection in children.the aim of this study was to determine risk factors for childhood sporadic reportable enteric infection (rei) caused by bacteria, specifically campylobacter, salmonella, escherichia coli o157, or shigella (rei-b).200919281302
