RISEffects of pH and temperature on antibacterial activity of zinc oxide nanofluid against Escherichia coli O157: H7 and Staphylococcus aureus
and characterized and then dispersed in glycerol with the help of ammonium citrate as the dispersant. The antibacterial tests were performed by measuring the growth of Escherichia coli O157:H7 and Staphylococcus aureus with different concentrations of ZnO NPs...
Quantification of Escherichia coli O157:H7 in milk by MPN-PCR method
-PCR using primers specific for O157 and H7
antigens gene.This MPN-PCR proved to be a rapid and reliable method for enumerating Escherichia coli O157:H7
in milk, including low contaminated samples and may facilitate the enumeration...
Growth response and modeling the effects of Carum copticum essential oil, pH, inoculum level and temperature on Escherichia coli O157:H7
Introduction and Objectives: Escherichia coli O157:H7 is an important human pathogen
causing hemorrhagic colitis, hemolytic-ureamic syndrome and thrombotic
thrombocytopenic purpura. Knowing the precise boundary for the growth-no growth...
A colorimetric aptasensor for rapid detection of Escherichia coli O157:H7
we have developed aptasensors-based on unmodified AuNPs that can rapidly detect E. coli O157:H7 with the naked eye. This sensor showed excellent selectivity toward E. Coli O157 with a limit of detection as low as 103 CFU/mL. ...
The effect of short-time microwave exposures on Escherichia coli O157:H7 inoculated onto beef slices
Escherichia coli O157:H7 is an important human pathogen causing haemorrhagic colitis, hemolyticureamic
syndrom and thrombotic thrombocytopenic purpura. In this study the effect of microwave
irradiation of beef samples which were...
the effct of microwave radiation in reducing the superficial contamination of red meat to escherichia coli O157:H7
Escherichia coli O157:H7 is an important human pathogen causing haemorragic colitis, haemolytic ureamic syndrom and thrombotic thrombocytopenic purpura....
Identification of shiga toxin producing Escherichia coli O157:H7 in raw cow milk samples from dairy farms in Mashhad using multiplex PCR assay
In this study number of 130 bulk tank milk samples which were delivered to Pegah pasturisation factory in Mashhad were collected randomly, during the summer months. For isolation of Escherichia coli O157:H7, samples were firstly enriched in modified...
Isolation and mulecular identification of Escherichia coli O157:H7 from ground beef samples collected from beef markets in Mashhad
Abstract:
Escherichia coli O157:H7 is an important human pathogen causing haemoragic colitis(HC), hemolytic-ureamic syndrom(HUS) and thrombotic thrombocytopenic purpura. A number of protocols for detection of Escherichia coli O157:H7...
Using multiplex-PCR assay in identification of Escherichia coli O157: H7 isolated from hamburger samples in Mashhad, Iran
and flagellar antigens. In this study, 9 NSF Escherichia coli colonies were isolated, and in multiplex-PCR assay two samples (4%) were confirmed as Escherichia coli O157:H7...
