Survey of bacterial genomes highlights the arsenal of enzymes microbes use to produce energy in the oxygen-poor environment of the gutPeer-Reviewed Publication UNIVERSITY OF CHICAGO The gut microbiome is so useful to human digestion and health that it is often called an extra digestive organ. This vast collection of bacteria and other microorganisms in the...

Research team develops polymers that can kill bacteria
by Shana K. Hutchins, Texas A&M University scherichia coli. Credit: Rocky Mountain Laboratories, NIAID, NIH Antibiotic-resistant bacteria have become a rapidly growing threat to public health. Each year, they account for more than 2.8 million infections, according to the U.S. Centers for Disease Control and Prevention. Without new antibiotics, even common injuries and infections harbor the...

Scientists uncover new way viruses fight back against bacteria
Peer-Reviewed Publication UNIVERSITY OF OTAGO A microscopic discovery will not only enable scientists to understand the microbial world around us but could also provide a new way to control CRISPR-Cas biotechnologies. An international team of researchers led by Professor Peter Fineran from the University of Otago and Dr Rafael Pinilla-Redondo from the University of Copenhagen...

Resistant Superbugs Killed by New Antibiotic From Bacterial “Dark Matter”
Previously “unculturable” bacteria could represent a source of novel antibiotics.Published: August 22, 2023 Sarah Whelan, PhD Credit: Markus Weingarth A study has isolated a powerful new antibiotic – clovibactin – from soil bacteria previously considered “unculturable”, demonstrating that it kills bacteria in a way that is less likely to lead to antibiotic resistance. The research...

Researchers engineer bacteria that can detect tumor DNA
by University of California – San Diego Upper: The bacterium A. baylyi can incorporate DNA from its environment through natural competence. This allows horizontal gene transfer and the integration of cell-free DNA into the A. baylyi genome. Lower: Researchers engineered A. baylyi to find the mutated KRAS gene, which helps colorectal cancers grow. Detection of tumor DNA activated...

Could endometriosis be caused by bacteria? Study offers fresh clues
Heidi Ledford Fusobacterium has been linked with endometriosis. Credit: CNRI/SPL Infection by a particular group of bacteria could be linked to endometriosis, a painful condition that affects up to 10% of women and girls of reproductive age. In a study of 155 women in Japan, members of the bacterial genus Fusobacterium were found in the uteruses of...

Bacteria With a Taste for Inflammatory Compound Could Protect Against Heart Disease
Some bacteria in the guts of humans and mice may help control plaque buildup in arteries, the leading cause of cardiovascular disease, by gobbling up a group of inflammatory chemicals before they can circulate. New research from the University of Wisconsin–Madison and collaborators worldwide identified microbes able to break down uric acid in the low-oxygen environment of the...

AI runs 10,000 experiments a day on bacteria to speed up discoveries
By Michael Irving May 08, 2023 A new AI platform called BacterAI can conduct thousands of experiments per day to learn about bacteria, even without any prior knowledge Depositphotos Scientific work often involves sifting through enormous amounts of data, a task that’s overwhelmingly mundane for humans but a piece of cake for artificial intelligence. A...
