Survival4
- Their manufacture does not involve a heat kill step to ensure the destruction of the organism, and the adverse conditions created during processing may not be sufficient to prevent E. coli O157:H7 survival. (umanitoba.ca)
- g-1 cocktail of E. coli O157:H7, surface applied with 4% or 6% (w/w) deodorized yellow mustard powder, and monitored for E. coli O157:H7 survival during 80d ham maturation. (umanitoba.ca)
- Since a 5 log kill of E. coli O157:H7 was achieved in control hams by the end of 80d, dry cured Westphalian ham manufacture would be considered capable of controlling the risk of E. coli O157:H7 survival by North American regulatory agencies. (umanitoba.ca)
- Improved understanding of the survival and transmission and survival of E. coli O157:H7 on the farm is essential for developing future controls of this pathogen. (teagasc.ie)
Significantly2
- After treatment for 60 s, numbers of surviving E. coli O157:H7 were generally higher than S. Typhimurium DT104, though significantly so only for chicken skin, indicating a possible difference in the heat resistance of the two organisms. (synbiosis.com)
- The E. coli O157 phage typing scheme exhibited a significantly modular network linked to the genetic similarity of each group showing that these groups are specialised to infect a subset of phage types. (biomedcentral.com)
Recombinant2
- Recombinant, E. coli recombinant proteins are genetic recombinations in Escherichia coli, supplied as white sterile powder lyopillized. (gentaur.com)
- This reagent contains a recombinant construct that may not represent the targeted genetic region for all possible assays analyzing for Escherichia coli O157. (gentaur.uk)
Cases2
- In the United States, HUS is the principal cause of acute kidney failure in children, and most cases of HUS are caused by E. coli O157:H7. (wikipedia.org)
- The median age of the non-O157 STEC cases was 23 years (range, 2 months to 88 years). (mn.us)
Sorbitol1
- Sorbitol nonfermenting colonies are tested for the somatic O157 antigen before being confirmed as E. coli O157:H7. (wikipedia.org)
Patterns1
- In Germany, E . coli O157:H7, which is the most frequent ased by subjective interpretation of band patterns ( 7 , 8 ). (cdc.gov)
Illnesses1
- Escherichia coli O157:H7 causes 73,000 illnesses in the United States annually. (cdc.gov)
Spinach1
- about the E. coli outbreak in 2006 in the United States that was traced to contaminated spinach. (cdc.gov)
