These NEWLY evolved strains of E. Coli present new dangers to everyone. The kidneys are the most prone to infection by these dangerous new strains of E.Coli. How bad is it ? Well, only 10 years ago there was only one strain of E.Coli that produced extremely harmful pathogens. Now there...
We show that the metY locus which specifies tRNA(2fMet) in Escherichia coli K-12 specifies tRNA(1fMet) in E. coli B. This conclusion is based on results of Southern blot analysis of E. coli B and K-12 DNAs and on polymerase chain reaction amplification, cloning, and sequencing of ...
Various species of the intestinal microbiota have been associated with the development of colorectal cancer1,2, but it has not been demonstrated that bacteria have a direct role in the occurrence of oncogenic mutations. Escherichia coli can carry the pathogenicity island pks, which encodes a set ...
Escherichia coli O157 is an important cause of food-borne illness. The primary reservoir for this organism is cattle and at present the major site of control is within abattoirs. Recent data have highlighted the importance of the pathogen load entering abattoirs on harvest-ready feedlot cattle. ...

interactions between two residue clusters with complementary electrostatics are observed in the undipped simulations (Fig.4f, Supplementary Table2). However, although interactions between one or both clusters are often present, the specific interaction partners within a cluster vary. Considering this lack...
Escherichia coli is exposed to wide extracellular concentrations of Ca2+, whereas the cytosolic levels of the ion are subject to stringent control and are implicated in many physiological functions. The present study shows that extracell... MC Theodorou,E Tiligada,DA Kyriakidis - 《Biochemical Journ...

Here we have constructed a yeast-Escherichia coli-Agrobacteriumshuttle vector that enables highly efficient homologous recombination in yeast for assembly ofAgrobacteriumcompatible plant virus clones. Using this vector, we show that infectious cDNA clones of a plant negative-stranded RNA virus, sonchus ...
