Escherichia coli 0157:H7

Microbiology A shiga-like verotoxin-producing serotype of E coli inculpated in outbreaks of hemorrhagic diarrhea, due to undercooked meat in 'fast-food' restaurants Clinical Colic, bloody diarrhea Radiology Submucosal edema, 'thumbprinting'

Escherichia coli 0157:H7

A strain of E. coli that may cause bloody diarrhea (and other more serious illnesses) as a result of its production of a potent toxin. Outbreaks of diarrheal illnesses caused by 0157:H7 have occurred in day care centers, families, farms, fast-food restaurants, nursing homes, petting zoos, and schools. The organism may contaminate undercooked meat, esp. hamburger; unpreserved apple cider; vegetables grown in manure; or contaminated water supplies. The infection caused by this bacillus may spread from animal-to-person, person-to-person, or through contamination of food or water.

Symptoms

Asymptomatic infection is common. In other cases, after the 3- to 8-day incubation period, an afebrile and self-limiting diarrhea occurs; however, the infection may progress to hemorrhagic colitis with bloody diarrhea, severe abdominal pain, and low-grade fever. Resolution usually occurs in 1 week. In about 15% of cases, patients develop hemolytic uremic syndrome (HUS); the mortality among patients who develop HUS ranges from 3 to 5%. The highest incidence of HUS is found among children and older adults.

Diagnosis

Without a high index of suspicion, diagnosis in either a lone case or an outbreak may be delayed. To prevent unnecessary diagnostic or therapeutic intervention, such as colonoscopy or colectomy, diagnosis should be made as quickly as possible.

Prevention

Ground meat should be cooked until it reaches a temperature of 160°F (71.1°C) and the meat should not be pink in the center. Leftovers should be reheated to 165°F (73.3°C). Individuals who change a baby's diapers should thoroughly wash their hands immediately afterward. Food handlers must wash their hands after using the toilet.

Escherichia

a genus of widely distributed gram-negative bacteria in the family Enterobacteriaceae.

Escherichia coli
a species constituting the greater part of the normal intestinal flora of animals. The organism most used in recombinant DNA work. Pathogenic strains a cause of urinary tract infections, epidemic diarrheal diseases, especially in newborn animals and late respiratory disease in broiler chickens. Also a common opportunistic pathogen. See colibacillosis, coliform mastitis, coliform gastroenteritis, avian coliform septicemia, mastitis-metritis-agalactia, enteropathogenic, enterotoxigenic shiga-like toxins.
Escherichia coli 0157:H7
a verotoxin producing E. coli that has been responsible for outbreaks of hemorrhagic colitis, especially in children, but in all ages. Case fatality rates can be high, especially where there is the complication of the hemolytic uremic syndrome (HUS). The organism is carried by cattle who show no sign of clinical disease and many outbreaks have been epidemiologically linked to food products of bovine origin. The mass handling and marketing of minced beef allow a contaminated batch to affect a large population. The infective dose for man is estimated at a few organisms and infection can also be picked up by children visiting petting zoos or on farm visits.
Escherichia coli J5 vaccine
vaccine prepared from E. coli mutant; provides protection against coliform mastitis in cows.
attaching and effacing Escherichia coli (AEEC)
produce shiga toxin (verotoxin). Certain serotypes cause enteritis, colitis and diarrhea in a number of different animal species by expressing a virulence factor protein called intimin which allows intimate attachment of the organism to the microvillus brush border of enterocyte forming a characteristic attaching and effacing lesion. Diagnosis is by the detection of the shiga toxin and characterisitic lesions.
Escherichia coli Shigella
a cluster of clones of E. coli that are unable to ferment lactose and that cause bacillary dysentery in primates, including humans, as a result of the independent acquisition of a specific virulence plasmid. Includes the organisms previously known as Shigella dysenteriae, S. flexneri, S. sonnei and S. boydii (now E. coli Dysenteriae, E. coli Flexneri, E. coli Sonnei and E. coli Boydii).
