The intestinal tract of ruminants, particularly cattle, have been regarded as the primary reservoir of STECs7, which normally does not cause any disease in animals. STEC have also been recovered from other domestic animals, such as sheep, goats, pigs, cats and dogs8, as well as wild animals...
The effect of an Escherichia coli regulatory mutation on transfer RNA structure - Eisenberg, Yarus, et al. - 1979 () Citation Context ...io6A modification that makes tRNA less sensitive to the base 39 of the codon seems to reside primarily in the isopentenyl group. DISCUSSION Studies with ...
As AIEC can colonise the gut and hence can reside in the intestine for considerable periods, the ability of their OMVs to induce ROS and DNA damage suggest that LF82 is, potentially, a significant risk for genotoxic damage within the gut. It is not known what components of DH5α and LF...
Escherichia coli is both a harmless commensal in the intestines of many mammals, as well as a dangerous pathogen. The evolutionary paths taken by strains of this species in the commensal-to-pathogen transition are complex and can involve changes both in
Early models of mutagenesis envisioned the Umu proteins as accessory factors to the cell’s replicase that not only reduced its normally high fidelity, but also allowed the enzyme to traverse otherwise replication-blocking lesions in the genome. However, these models underwent a radical revision ...
Molecular Mechanisms of Phosphate Homeostasis in Escherichia coli 335 http://dx.doi.org/10.5772/67283 The presence of the PhoBR signal transduction system underscores the need for maintaining a minimal intracellular level of Pi when extracellular Pi is limiting. That too much intracellular Pi can ...
The inner membrane-anchored periplasmic folding factor PpiD is described as a parvulin-like peptidyl prolyl isomerase (PPIase) that assists in the maturation of the major beta-barrel outer membrane proteins (OMPs) of Escherichia coli. More recent work ho

Extraintestinal Pathogenic Escherichia coli (ExPEC) pose a significant threat to human and animal health. However, the diversity and antibiotic resistance of animal ExPEC, and their connection to human infections, remain largely unexplored. The study per
coli to oxygen deprivation was investigated. With our novel method, we detected, as expected, an up-regulation in the pathways of hexose nutrients up-take and metabolism and formate fermentation. Furthermore, our approach revealed a down-regulation in iron processing as well as the up-regulation...
