Tagging of the type three secretion system basal apparatus of Enterohaemorrhagic Escherichia coli 0157:H7
… negative bacterial pathogens Enterohaemorrhagic Escherichia coli (EHEC) O157:H7 possesses a type III secretion system (T3SS). The T3SS translocates effector proteins into host cells during infection and consists of a basal apparatus that spans the inner and outer membranes and a needle and …

Optimization of automated immunomagnetic separation for the detection of escherichia coli 0157: H7 by quantitative polymerase chain reaction
Escherichia coil 0157:1-17 is a virulent human pathogen responsible for severe bloody diarrhoea, haemorrhagic colitis and haemolytic uraemic syndrome. Carriage of the organism through the food chain can result in contamination of raw meat, dairy products, crops and produce during production. …

Efficacy of selected chemicals and electron beam irradiation for destroying Escherichia coli 0157:H7 and Salmonella on cantaloupe skin
… sulfate (1% SLS), and irradiation for destroying Escherichia coli 0157:H7 and Salmonella spp. on the outer rind surface of cantaloupe. Cantaloupe rinds were cut into 2.5 cm2 pieces and inoculated with either a five strain mixture of nalidixic acid resistant Salmonella spp. or E. coli to give …

The effect of heat shock, growth atmosphere, and recovery atmosphere on the survival of Escherichia coli 0157:H7 to heat
E. coli 0157:H7 is an important foodborne pathogen, responsible for several outbreaks of hemorrhagic colitis where improperly cooked hamburger meat was thought to be the vehicle. Various time/temperature combinations were used to determine the optimum conditions of heat shock which would result in …

Analysis of Campylobacter jejuni, Campylobacter coli, Salmonella, Klebsiella pneumoniae, and Escherichia coli 0157:H7 in fresh hand picked blue crab (Callinectes sapidus) meat
… of Campylobacter jejuni, Campylobacter coli, Salmonella, fecal positive Klebsiella pneumoniae, and Escherichia coli 0157:H7 in fresh hand picked blue crab (Callinectes sapidus) meat. An attempt was made to correlate these selected pathogens and general microbial quality to processors …

The Effect of Sorbic Acid on the Survival oOf Escherichia coli 0157:H7, Salmonella, Listeria monocytogenes, and Staphylococcus aureus on Shredded Cheddar and Mozzarella Cheese
… the effectiveness of sorbic acid in inhibiting Escherichia coli 0157:H7, Salmonella spp., Listeria monocytogenes, and Staphylococcus aureus on shredded cheddar and mozzarella cheese over 70 days storage. Samples of cheese were inoculated and placed into bags with a sorbic acid (0, 0.1, 0.15, 0.2 …

Study of poly(phenylene ethynylene)s, dendritic quenchers, and molecular beacons towards the application of a poly(phenylene ethynylene)-based biosensor
… known as a molecular beacon (MB) selective for Escherichia coli 0157:H7. In order to continue expanding the scope of PPEs in sensor applications, new handles are required with which to manipulate the polymers. These handles should be designed so as to tether small molecules, cross-linkers, and …

Interactions of shiga-like toxin-2 (Stx-2) from Escherichia coli O157:H7 and the Bcl-2 family of proteins during host cell programmed cell death
… is a major contributor to the pathogenesis of Escherichia coli 0157:H7. Prior reports suggest that Stx-2 increases necrosis and apoptosis of a variety of host cells including those of endothelial origin as well as immune cells such as neutrophils (156). However, the role Stx-2 plays in delayed …
