Dramatic Transition in Streptomyces Life Cycle Explained in New Discovery

Streptomyces bacteria are our primary source of antibiotics, which are produced in the transition from vegetative growth to sporulation in a complex developmental life ... read more

How the Strep Bacterium Hides from the Immune System

A bacterial pathogen that causes strep throat and other illnesses cloaks itself in fragments of red blood cells to evade detection by the host immune system, according to a new study. The researchers ... read more

Space Travel Can Make the Gut Leaky

Bacteria, fungi, and viruses can enter our gut through the food we eat. Fortunately, the epithelial cells that line our intestines serve as a robust barrier to prevent these microorganisms from ... read more

Scientists Dissect and Redesign Protein-Based Pattern Formation

Probing the functional segments, or 'motifs', of proteins has helped scientists identify the minimal ingredients needed for them to form biological ... read more

Coated Seeds May Enable Agriculture on Marginal Lands

Providing seeds with a protective coating that also supplies essential nutrients to the germinating plant could make it possible to grow crops in otherwise unproductive soils, according to new ... read more

How Diversity of Respiratory Quinones Affects Microbial Physiology

A new study provides a fundamental understanding of the diversification of small molecules called respiratory quinones and its adaptive consequences in bacterial species. Bioengineers specifically ... read more

Gut Microbes Alter Characteristics of Norovirus Infection

The highly contagious norovirus causes diarrhea and vomiting and is notorious for spreading rapidly through densely populated spaces, such as cruise ships, nursing homes, schools and day care ... read more

The Nature of Salmonella Is Changing -- And It's Meaner

Salmonella is acting up in Michigan, and it could be a model for what's happening in other states, according to a new ... read more

Antibiotic-Resistant Bacteria More Prevalent in Device-Related Infections

Healthcare-associated infections (HAIs) related to the use of medical devices are more likely to be antibiotic resistant than HAIs that result from surgical procedures, according to a new ... read more

Bacteria-Infecting Viruses Bind Mucosal Surface and Protect from Disease

Bacteriophages, viruses that infect bacteria, have been shown to preferentially bind to mucosal surfaces. This has been suggested to provide an extra level of immunity against bacterial infections. ... read more

In a First for Cell Biology, Scientists Observe Ribosome Assembly in Real Time

A team of scientists has recorded in real time a key step in the assembly of ribosomes -- the complex and evolutionarily ancient 'molecular machines' that make proteins in cells and are ... read more

Magnesium Deprivation Stops Pathogen Growth

When pathogens invade the cells, our body combats them using various methods. Researchers have now been able to show how a cellular pump keeps such invading pathogens in check. As the researchers ... read more

A New Antibiotic to Combat Drug-Resistant Bacteria Is in Sight

Researchers have discovered a new active substance effective against gram negative bacteria that targets a previously unknown site of action: ... read more

Trials Promise Good News for Countries With Dengue and Zika Virus

Scientists have found an effective and environmentally sustainable way to block the transmission of mosquito-borne dengue virus, in trials carried out in ... read more

Turning to Old Remedies for New Health Challenges: Super-Bugs

The last thing anyone wants during a stay in the hospital is a hospital-acquired infection. Nosocomial infections, as they are called, are on the rise as more pathogens become resistant to drugs ... read more

Researchers Visualize Bacteria Motor in First Step Toward Human-Produced Electrical Energy

Humans, one day, may be able to produce their own electrical energy in the same way electric eels do, according to a research team. It's the ultimate goal that begins with understanding ... read more

Mapping the Pathway to Gut Health in HIV and SIV Infections

A new study found that Lactobacillus plantarum bacteria rapidly repaired damaged gut lining (known as leaky gut) in monkeys infected with chronic simian immunodeficiency virus (SIV), an HIV-like ... read more

Deep-Sea Bacteria Copy Their Neighbors' Diet

A new group of symbiotic bacteria in deep-sea mussels surprises with the way they fix carbon: They use the Calvin cycle to turn carbon into tasty food. The bacteria acquired the genes for this ... read more

Antibiotics from the Sea

Biologists have succeeded in cultivating several dozen marine bacteria in the laboratory -- bacteria that had previously been paid little attention. The researchers then carried out a functional ... read more
