| outbreak of escherichia coli o157:h7 and campylobacter among attendees of the washington county fair-new york, 1999. | september 3, 1999, the new york state department of health (nysdoh) received reports of at least 10 children hospitalized with bloody diarrhea or escherichia coli o157:h7 infection in counties near albany, new york. all of the children had attended the washington county fair, which was held august 23-29, 1999; approximately 108,000 persons attended the fair during that week. subsequently, fair attendees infected with campylobacter jejuni also were identified. an ongoing investigation includes he ... | 1999 | 10499785 |
| prevalence of escherichia coli o157:h7 from cull dairy cows in new york state and comparison of culture methods used during preharvest food safety investigations. | a number of protocols for the cultural detection of escherichia coli o157:h7 in clinical fecal specimens have been proposed. in the present study direct plating of cattle feces was compared to three different broth enrichment protocols, i.e., a protocol with modified e. coli broth with novobiocin, a protocol with trypticase soy broth with cefixime and vancomycin, and a protocol with gram-negative broth with novobiocin, for their relative abilities to detect e. coli o157:h7 in feces. in all enric ... | 2000 | 10618108 |
| evaluation of the reveal and safepath rapid escherichia coli o157 detection tests for use on bovine feces and carcasses. | the reveal (neogen corp., lansing, mich.) and safepath (safepath laboratories llc, st. paul, minn.) tests were evaluated for their performance as beef fecal and beef carcass escherichia coli o157:h7 monitoring tests. agreement between these tests and a reference test system was determined using naturally contaminated bovine feces and beef carcasses. the reference system utilized immunomagnetic separation with plating onto cefixime, tellurite, sorbitol macconkey agar, followed by colony testing u ... | 2000 | 10914650 |
| detection, isolation, and molecular subtyping of escherichia coli o157:h7 and campylobacter jejuni associated with a large waterborne outbreak. | the largest reported outbreak of waterborne escherichia coli o157:h7 in the united states occurred in upstate new york following a county fair in august 1999. culture methods were used to isolate e. coli o157:h7 from specimens from 128 of 775 patients with suspected infections. campylobacter jejuni was also isolated from stools of 44 persons who developed diarrheal illness after attending this fair. there was one case of a confirmed coinfection with e. coli o157:h7 and c. jejuni. molecular detec ... | 2003 | 12517844 |
| hemolytic uremic syndrome incidence in new york. | a comparison of new york's traditional communicable disease surveillance system for diarrhea-associated hemolytic uremic syndrome with hospital discharge data showed a sensitivity of 65%. escherichia coli o157:h7 was found in 63% of samples cultured from hemolytic uremic syndrome patients, and samples were more likely to be positive when collected early in illness. | 2004 | 15200834 |
| importance of culture confirmation of shiga toxin-producing escherichia coli infection as illustrated by outbreaks of gastroenteritis--new york and north carolina, 2005. | escherichia coli o157:h7 and other strains of e. coli that produce shiga toxin are collectively known as shiga toxin-producing e. coli (stec). the current outbreak of stec o157 infections associated with eating fresh spinach illustrates the importance of obtaining isolates to identify the source of the infections. laboratory methods that do not require bacterial culture of stool specimens to identify stec are being used increasingly by clinical diagnostic laboratories, sometimes without subseque ... | 2006 | 17008867 |
