Portable nanodevice provides rapid, accurate diagnosis of tuberculosis, other bacterial infections
A handheld diagnostic device that Massachusetts General Hospital (MGH) investigators first developed to diagnose cancer has been adapted to rapidly diagnose tuberculosis (TB) and other important infectious ...

Human, soil bacteria swap antibiotic-resistance genes: study
Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.
Single gene mutation can sweep through bacterial population, opening the door for the concept of 'species'
Bacteria are the most populous organisms on the planet. They thrive in almost every known environment, adapting to different habitats by means of genetic variations that provide the capabilities essential ...
Bacteria develop restraint for survival in a rock-paper-scissors community
It is a common perception that bigger, stronger, faster organisms have a distinct advantage for long-term survival when competing with other organisms in a given community.
New insights into antibiotic resistance: Researchers find charitable behavior in bacteria
In the war against antibiotics, bacteria aren't selfish. According to a new report from Howard Hughes Medical Institute (HHMI) researchers, a handful of resistant pathogens can protect an entire colony.
New study overturns orthodoxy on how macrophages kill bacteria
For decades, microbiologists assumed that macrophages, immune cells that can engulf and poison bacteria and other pathogens, killed microbes by damaging their DNA. A new study from the University of Illinois ...
Pig-borne disease most likely jumped into humans when rearing practices changed
Almost every pig carries harmless strains of the S. suis bacterium - such strains are known as 'commensal' strains. However, a more virulent group of strains of the bacteria also exist, which cause disease ...
Researcher discovers new salmonella serotype
Lubbock is known for many things. Some of them are reasons to celebrate, like being the home of Buddy Holly. Some portray the city in negative ways, like dust storms.
Bacteria's game of 'Telephone' foils microbiologists' eavesdropping
While human families are easily illustrated as a tree, bacterial families look more like a heap of branches. Scientists are trying to trace the connections between those branches in an effort to learn more ...
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.
Engineered for tolerance, bacteria pump out higher quantity of renewable gasoline
An international team of bioengineers has boosted the ability of bacteria to produce isopentenol, a compound with desirable gasoline properties. The finding, published in mBio, the online open-access journa ...
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 ...
Prions can trigger 'stuck' wine fermentations, researchers find
A chronic problem in winemaking is "stuck fermentation," when yeast that should be busily converting grape sugar into alcohol and carbon dioxide prematurely shuts down, leaving the remaining sugar to instead ...
