Validation of the ANSR®E. coli O157:H7 Method for Detection of E. coli O157:H7

Journal of AOAC INTERNATIONAL, 2016
Abstract A performance validation of the ANSR® for E. coli O157:H7 method was conducted in selected food matrixes. This assay uses selective nicking enzyme amplification technology to amplify target genes. Samples are enriched for 12–24 h and then lysed.

THE EFFECT OF E. COLI O157:H7 ON BEEF PRICES

Journal of Agricultural and Resource Economics, 2001
Using an event study, we examine the impact of recalls for E. Coli O157:H7 on wholesale and farm-level beef prices. Prices for boneless beef, a high-volume product primarily used for processing into ground beef, react negatively to recalls, suggesting incentives exist for packing firms to adopt measures that reduce the risk of contamination.

Performance of the ImmunoCard STAT! E. coli O157:H7 Test for Detection of Escherichia coli O157:H7 in Stools [PDF]

Journal of Clinical Microbiology, 2000
ABSTRACT ImmunoCard STAT! E. coli O157:H7 (Meridian Diagnostics, Inc., Cincinnati, Ohio) is a novel rapid (10-min) test for the presence of Escherichia coli O157:H7 in stools. The test may be performed either directly on stool specimens or on an overnight broth culture of stool.

EFFECT OF SIDEROPHORES AGAINST E. COLI O157:H7

Italian Journal of Food Safety, 2012
In this study, the inhibiting activity of siderophores produced by Pseudomonas fluorescens against Escherichia coli O157:7 was assayed. Siderophores were extracted from P. fluorescens cultures and preliminarily tested by C.A.S. reagent and UV. The siderophores activity against E. coli O157:H7 was characterised by the determination of Minimal Inhibiting

Assessment of resistance to colicinogenic Escherichia coli by E. coli O157:H7 strains [PDF]

Journal of Applied Microbiology, 2005
To assess a collection of 96 Escherichia coli O157:H7 strains for their resistance potential against a set of colicinogenic E. coli developed as a probiotic for use in cattle.Escherichia coli O157:H7 strains were screened for colicin production, types of colicins produced, presence of colicin resistance and potential for resistance development ...

Validation of a Modified ANSR® for E. coli O157:H7 Method for Detection of E. coli O157:H7 in Select Foods

Journal of AOAC INTERNATIONAL, 2019
Abstract Background: The ANSR method is based on isothermal nucleic acid amplification technology. The modifications to assay components improve sensitivity of the assay and robustness of the internal positive control. Objective: A Performance Tested MethodSM validation study was conducted to assess performance of a modified version of ...

Sharp Transition in the Immunoimmobilization of E. coli O157:H7

Langmuir, 2014
This work focuses on immobilization of living enterohemorrhagic Escherichia coli O157:H7 on a gold surface as a function of the concentration of antibody tethered to the surface in the physiological environment of the organisms. Experiments are conducted using antibodies raised against bacterial surface lipopolysaccharides (LPS) tethered to gold-coated
