Study of the Effects of High-Energy Proton Beams on Escherichia Coli [PDF]

arXiv, 2015
Antibiotic-resistant bacterial infection becomes one of the most serious risks to public health care today. However, discouragingly, the development of new antibiotics has been little progressed over the last decade. There is an urgent need of the alternative approaches to treat the antibiotic-resistant bacteria.

Dynamic detection of a single bacterium: nonlinear rotation rate shifts of driven magnetic microsphere stages [PDF]

arXiv, 2006
We report on a new technique which was used to detect single Escherichia coli that is based on the changes in the nonlinear rotation of a magnetic microsphere driven by an external magnetic field. The presence of one Escherichia Coli bacterium on the surface of a 2.0 micron magnetic microsphere caused an easily measurable change in the drag of the ...

Prevalence of Antibiotic Resistance and Distribution of Virulence Factors in the Shiga Toxigenic Escherichia coli Recovered from Hospital Food

Jundishapur Journal of Microbiology, 2019
Background: Regarding the presence of immunosuppressed patients in hospitals, hospital food must have a boost safety. Escherichia coli O157 is one of the prevalent causes of food-related poisoning.

Phenotypic characteristics, virulence profile and genetic relatedness of O157 Shiga toxin-producing Escherichia coli isolated in Brazil and other Latin American countries [PDF]

, 2006
Thirty-eight Shiga toxin-producing Escherichia coli (STEC) O157:H7/H- strains isolated from human infections, cattle and foods in Brazil and in some other Latin American countries were compared with regard to several phenotypic and genotypic ...

A generalization of Kingman's model of selection and mutation and the Lenski experiment [PDF]

arXiv, 2015
Kingman's model of selection and mutation studies the limit type value distribution in an asexual population of discrete generations and infinite size undergoing selection and mutation. This paper generalizes the model to analyse the long-term evolution of Escherichia. coli in Lenski experiment.

Target genes for virulence assessment of Escherichia coli isolates from water, food and the environment [PDF]

, 2017
The widespread species Escherichia coli includes a broad variety of different types, ranging from highly pathogenic strains causing worldwide outbreaks of severe disease to avirulent isolates which are part of the normal intestinal flora or which are ...

Phylogenetic and Molecular Analysis of Food-Borne Shiga Toxin-Producing Escherichia coli [PDF]

, 2013
Seventy-five food-associated Shiga toxin-producing Escherichia coli (STEC) strains were analyzed by molecular and phylogenetic methods to describe their pathogenic potential.

Pattern formation within Escherichia coli: diffusion, membrane attachment, and self-interaction of MinD molecules [PDF]

, 2004
In E. coli, accurate cell division depends upon the oscillation of Min proteins from pole to pole. We provide a model for the polar localization of MinD based only on diffusion, a delay for nucleotide exchange, and different rates of attachment to the bare membrane and the occupied membrane.

The influence of the accessory genome on bacterial pathogen evolution [PDF]

, 2011
Bacterial pathogens exhibit significant variation in their genomic content of virulence factors. This reflects the abundance of strategies pathogens evolved to infect host organisms by suppressing host immunity.

Occurrence of virulence genes associated with diarrheagenic pathotypes in Escherichia coli isolates from surface water [PDF]

, 2013
Escherichia coli isolates (n=300) collected from six sites in subtropical Brisbane, Australia, prior to and after storm events were tested for the presence of 11 virulence genes (VGs) specific to diarrheagenic pathotypes.
