Researchers at Instituto Gulbenkian de Ciência (IGC) in Portugal and Stanford in the US have identified one particular bacterium, Klebsiella michiganensis, that could be administered after a round of antibiotics to help prevent harmful infections.
Phages, viruses that thrive by infecting bacteria, have long been mooted as a potential replacement for antibiotics, but they pose risks due to their own rapid evolution. New research suggests it may be possible to mitigate their risks.
Antibiotics are one of the most important medical marvels of the modern age, letting us easily treat infections that would have once been lethal. The problem is they aren't picky, blasting good and bad bacteria alike and messing up the delicate balance of the gut microbiome. But now researchers have developed a more targeted approach, with drugs that are able to zero in on specific species
The over-prescription of antibiotics is a major problem in the world today, leading to the dramatic rise of antibiotic-resistant bacteria. New research led by scientists from the Francis Crick Institute in London is suggesting not only are antibiotics ineffective for individuals suffering from influenza, but they can actually worsen the initial viral infection...

Antibiotics were one of the most important scientific developments of the 20th century, helping to easily control bacterial infections and make previously life-threatening procedures and illnesses safe. But inversely, they might also be one of the biggest medical issues of the 21st century, as bacteria evolve resistances to our best drugs. Now, a bacterial gene that grants resistance to "l
Evolution is an incredible process, allowing life to adapt to changes in its environment. In the 1990s, the lab of Frances Arnold showed how we can turn this process to our advantage by manipulating microbes into evolving in a certain way, which could lead to new drugs and other breakthroughs. The discovery earned Arnold the 2018 Nobel Prize in Chemistry, and now her team is using the tech
Bacteria are quickly evolving resistances to antibiotics, to the extent that our best drugs might not work in the terrifyingly-near future. Scientists are hard at work developing new antibiotics, or finding ways to make existing ones more effective. Now, researchers from Thomas Jefferson University have found a new way to weaken bacterial defenses, slowing down the development of antibioti
For such simple organisms, bacteria are surprisingly crafty when it comes to defending themselves from antibiotics. They build biofilms to protect colonies, hibernate until the danger passes, and of course they're steadily evolving genetic resistances to our best drugs. Now researchers at Princeton and California State University-Northridge have discovered a new bacterial defense mechanism
As we rapidly discover the importance a rich and diverse gut microbiome has on our overall health, some researchers are beginning to ask what the impact of widespread antibiotic use has been on our gut bacteria. A new study has closely examined the regrowth in gut bacteria after major antibiotic interventions, revealing that while much of our microbiome does recover, some species could be
We're currently locked in an arms race against bacteria, and the bugs are winning as they continue to evolve resistance to our best drugs. Luckily, we have some double agents in the war – probiotics, or "good" bacteria that help keep bad bugs at bay. And now, MIT researchers have found a way to combine probiotics and antibiotic drugs into an uneasy alliance that seems to work better than e
