| molecular characterisation of escherichia coli o157:h7 isolates by pulsed-field gel electrophoresis and plasmid dna analysis. | foods of bovine origin have been identified as sources of escherichia coli o157:h7. genomic dna of e. coli o157:h7 isolates from patients (six isolates), food samples (18 isolates from ground beef and six isolates from raw milk) and calf faecal samples (31 isolates) were characterised by pulsed-field gel electrophoresis (pfge) and plasmid dna analysis. these isolates originated from different locations in the usa during 1992 and 1993. twenty-one distinct genomic profiles were generated from the ... | 1995 | 7707333 |

| outbreak of escherichia coli o157:h7 infection--georgia and tennessee, june 1995. | on june 26, 1995, the division of public health, georgia department of human resources (gdph), was notified of three cases of escherichia coli o157:h7 infection among residents of a community in north georgia who had onsets of illness within a 24-hour period (onset during june 19-20); in comparison, during 1993-1994, only two cases of this infection had been reported in the same community. because of the proximity of this community to the tennessee border, on june 28 gdph notified the tennessee ... | 1996 | 8965785 |
| survival of enterohemorrhagic escherichia coli o157:h7 in water. | several recent escherichia coli o157:h7 outbreaks associated with both drinking and recreational water raise concerns about waterborne illness caused by this pathogen. the survival characteristics of a mixture of five nalidixic acid-resistant e. coli o157:h7 strains (10(3) cfu/ml) in filtered and autoclaved municipal water, in reservoir water, and in water from two recreational lakes were determined for a period of 91 days at 8, 15 or 25 degrees c. greatest survival was in filtered autoclaved mu ... | 1998 | 9709245 |
| incidence of foodborne illnesses reported by the foodborne diseases active surveillance network (foodnet)-1997. foodnet working group. | in 1997, the foodborne diseases active surveillance program (foodnet) conducted active surveillance for culture-confirmed cases of campylobacter, escherichia coli o157, listeria, salmonella, shigella, vibrio, yersinia, cyclospora, and cryptosporidium in five emerging infections program sites. foodnet is a collaborative effort of the centers for disease control and prevention's national center for infectious diseases, the united states department of agriculture's food safety and inspection servic ... | 2000 | 10852576 |
| prevalence of parasites in fecal material from chlorinated swimming pools--united states, 1999. | as a result of the 1998 outbreak of infection with the chlorine-sensitive pathogen escherichia coli o157:h7 at a waterpark in georgia, many public health departments updated their guidelines for disinfecting pools following a fecal accident. many of these guidelines recommended treating all fecal accidents as if they contained the highly chlorine-resistant parasite cryptosporidium parvum, generally resulting in hyperchlorination and pool closures of up to a day. to determine whether fecal accide ... | 2001 | 11400955 |
| washing practices on the microflora on georgia-grown cantaloupes. | in recent years, several foodborne illness outbreaks have been associated with the consumption of cantaloupe. cantaloupes can be contaminated with pathogens anywhere from the field to the packing line. in the united states, cantaloupes are handled and packed differently in each state. georgia-grown cantaloupes are brought to sheds, washed, and packed, whereas california-grown cantaloupes are field packed. in this study, the microbiological status of cantaloupes produced by four georgia growers t ... | 2008 | 18236661 |
| survival dynamics of fecal bacteria in ponds in agricultural watersheds of the piedmont and coastal plain of georgia. | animal agriculture in watersheds produces manure bacteria that may contaminate surface waters and put public health at risk. we measured fecal indicator bacteria (commensal escherichia coli and fecal enterococci) and manure pathogens (salmonella and e. coli 0157:h7), and physical-chemical parameters in pond inflow, within pond, pond outflow, and pond sediments in three ponds in agricultural watersheds. bishop pond with perennial inflow and outflow is located in the piedmont, and ponds a and c wi ... | 2012 | 22088271 |
| ground beef handling and cooking practices in restaurants in eight states. | eating in table-service restaurants has been implicated as a risk factor for escherichia coli o157:h7 infection. to explore this association and learn about the prevalence of risky ground beef preparation practices in restaurants, the environmental health specialists network (ehs-net) assessed ground beef handling policies and practices in restaurants in california, colorado, connecticut, georgia, minnesota, new york, oregon, and tennessee. eligible restaurants prepared and served hamburgers. eh ... | 2013 | 24290692 |
