Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
'Lonely' bacteria increase risk of antibiotic resistance
Scientists from The University of Manchester have discovered that 'lonely' microbes are more likely to mutate, resulting in higher rates of antibiotic resistance.
Scientists understand how E. coli clone has become globally distributed
Scientists have for the first time come closer to understanding how a clone of E. coli, described as the most important of its kind to cause human infections, has spread across the world in a very short time. ...
Another reason to be thankful: Turkeys may be lifesavers
While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day.
New antibiotic in mushroom that grows on horse dung
Researchers from the Institute of Microbiology at ETH Zurich have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. Researchers are now exploring the various potential ...
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Tick protein does the trick to fight infection
A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.
Designer viruses could be the new antibiotics
Bacterial infections remain a major threat to human and animal health. Worse still, the catalogue of useful antibiotics is shrinking as pathogens build up resistance to these drugs. There are few promising ...
Using test tube experiments to study how bacterial species evolve antibiotic resistance
Given a critical change in the environment, how exactly, do species adapt? Professor Tom Vogwill and colleagues wanted to get at the heart of this evolutionary question by measuring the growth rates and DNA mutations of 8 ...
Study shows manure from cows not given antibiotics still causes increase in resistant bacteria in soil
A novel roadmap through bacterial genomes leads the way to new drug discovery
For millennia, bacteria and other microbes have engaged in intense battles of chemical warfare, attempting to edge each other out of comfortable ecological niches. Doctors fight pathogens with an arsenal of weapons—antibiotics—co-opted ...
'Programmable' antibiotic harnesses an enzyme to attack drug-resistant microbes
The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating ...
Attacking persister cells that are responsible for making bacteria resistant to new drugs
(Phys.org) —We face an urgent global health problem because scientists are not developing new antibiotics as fast as bacteria are developing antibiotic resistance.
