Figure 1: Genomic locations and variability of E. coli housekeeping genes. Knowing that the underlying network is tree-like, we inferred a phylogeny for the strains that were based on sequences of ...

In this work, we aimed to detect antimicrobial resistance genes from the human oral metagenome ... of the human oral metagenomic DNA library E. coli was then screened against various antimicrobial ...

Professor Tracy Palmer and her colleagues have taken three genes identified through sequencing of the E. coli genome and studied them to discover their significance. Professor Palmer said ...

The new genes also help explain why E. coli O157:H7 infections are sometimes difficult to treat, says Guy Plunkett III, Ph.D., a geneticist at UW-Madison. The reason is that certain antibiotics ...

Over the past fifty years, scientists have mapped 1,378 interactions among E. coli genes. Out of that research, Yang and his colleagues built a microbial call graph. They assigned each gene to one ...

Escherichia coli O104 is an emergent disease-causing bacterium ... Moreover, it has acquired genes through horizontal transfer from other strains that make it even more virulent than others.

Like most living things that aren’t plants, E. coli can’t use carbon dioxide as food. Until now. After inserting new genes, the Israel-based researchers used laboratory evolution to pressure E.

coli. It may even be able to predict the future. E. coli has 4000-odd genes, which it can use in various combinations to meet the many challenges it faces. But it does not use all those genes to ...

The energy budget of E. coli is pretty tight -- it's been said that even adding an extra base to a gene will make the bacterial lineage less fit. In the absence of selective forces of antibiotics ...

Therefore, when E. coli grow on sources other than lactose, such as carbon-based sources, these genes are not transcribed, leading to a very low concentration of these enzymes in the cell.

To shed some light on that, the researchers engineered a pathogenic strain of E. coli so that when a gene associated with the "colonization phase" is activated, a particular protein is expressed ...
