The objective of this work was to molecularly and genotypically characterize test the inhibitory activity six colicinogenic Escherichia coli strains (ColEc) their partially purified colicins against STEC O157:H7 isolated from clinical human cases. Inhibition tests demonstrated these O157:H7. By PCR it possible detect Ia, E7, B microcins M, H47, C7, J25. genome sequencing two selected ColEc stra...

background and objectives: the most common serotype of enterohaemorrhagic esherichia coli group or shiga-toxin-producing e. coli is o157:h7. domestic and wild ruminants are regarded as the main natural reservoirs. o157:h7 serotype is the major cause of gastrointestinal infections in developed countries. in this study was conducted to survey on the toxigenic e. coli o157: h7 strains in milk of i...

AIMS Survival of Escherichia coli O157:H7 and nonpathogenic E. coli on spinach leaves and in organic soil while growing spinach in a growth chamber was investigated. METHODS AND RESULTS Spinach plants were maintained in the growth chamber at 20 degrees C (14 h) and 18 degrees C (10 h) settings at 60% relative humidity. Five separate inocula, each containing one strain of E. coli O157:H7 and o...

Escherichia coli EDL933 is the prototypic strain for enterohemorrhagic E. coli serotype O157:H7, associated with deadly food-borne outbreaks. Because the publicly available sequence of the EDL933 genome has gaps and >6,000 ambiguous base calls, we here present an updated high-quality, unambiguous genome sequence with no assembly gaps.

We analyzed isolates of Escherichia coli O157:H7 (which has recently caused waterborne outbreaks) and wild-type E. coli to determine their sensitivity to chlorination. Both pathogenic and nonpathogenic strains were significantly reduced within 1 minute of exposure to free chlorine. Results indicate that chlorine levels typically maintained in water systems are sufficient to inactivate these org...

Shiga toxin-producing Escherichia coli O157:H7 causes foodborne infections, and cattle are the primary reservoir. Some animals, known as supershedders, excrete orders of magnitude more E. coli O157:H7 in the feces than normal. Here, we report the complete genome sequence of the SS52 supershedder strain of E. coli O157:H7.

Enterohemorrhagic Escherichia coli (EHEC) of the O157:H7 serotype is a worldwide zoonotic pathogen responsible for the majority of severe cases of human EHEC disease. The aim of the present study was to investigate the prevalence of E. coli O157: H7/NM in raw meat samples from two provinces of Iran. During a period from March 2010 to March 2011. Two hundred and ninety five raw meat samples were...

We previously demonstrated that application of bacteriophages significantly reduced Escherichia coli O157:H7 contamination in spinach and ground beef. Here, we present the genomic sequences of two bacteriophages, vB_EcoS_FFH_1, a T5-like phage, and vB_EcoM_FFH_2, an rV5-like phage, used in those treatments.

The stimulating effect of subinhibitory concentrations of antibiotics on the production of verocytotoxin (VT) by enterohaemorrhagic Escherichia coli (EHEC) O157:H7 has been claimed. The purpose of this study was to find an alternative, but bioactive medicine for the treatment of this organism. Fifty-eight preparations of aqueous and ethanolic extracts of 38 medicinal plant species commonly used...
