development of a bacteriophage typing system for campylobacter jejuni and campylobacter coli.a bacteriophage typing system for campylobacter jejuni and campylobacter coli was developed with phages isolated from poultry feces. data for phage selection were generated from a set of isolates of c. jejuni and c. coli from humans in illinois. selection of 14 phages from the 47 phages available was assisted by determination of the sneath-jaccard similarity coefficients and subsequent unweighted pair-group arithmetic averaging cluster analysis. the typing set was reproducible and stable in the ...19854019737

pork producers' attitudes, knowledge, and production practices that relate to on-farm food safety.a survey was distributed by mail to a random selection of illinois pig farmers marketing 1,000 or more pigs in 1998 to assess their knowledge, attitude and behavior regarding on-farm food safety. valid responses were received from 353 of the 946 surveys mailed (37.3%). pork production accounted for more than 50% of gross agricultural revenues among 65.0% of respondents, and 91.2% were classified as "owner-operators." knowledge of food-borne pathogens was mixed, with correct responses to question ...200111770625
seasonal stability of cladophora-associated salmonella in lake michigan watersheds.the bacterial pathogens shigella, salmonella, campylobacter, and shiga toxin-producing e. coli (stec) were recently found to be associated with cladophora growing in southern lake michigan. preliminary results indicated that the salmonella strains associated with cladophora were genetically identical to each other. however, because of the small sample size (n=37 isolates) and a lack of information on spatial-temporal relationships, the nature of the association between cladophora and salmonella ...200919059626
campylobacter infections in the united states. results of an 11-state surveillance.in january 1982, 11 states (alabama, arizona, georgia, illinois, minnesota, new mexico, oregon, texas, vermont, washington, and wisconsin) began reporting monthly their isolations of campylobacter to the centers for disease control in atlanta. the information reported included the species of campylobacter organisms, the week of the report, the site from which the organism was isolated, and the age and sex of the infected person. a total of 3,966 isolates were reported in 1982, of which 3,900 wer ...19846087756
