Bacteria of the genus Legionella have evolved a sophisticated system to replicate in the phagocytic cells of their hosts. LMU researchers have now identified a novel component of this system.
In humans, Legionella is responsible for the so-called Legionnaires’ disease, a form of bacterial pne... Read More
Over the last decade or so, biologists have mustered an ever-growing appreciation for the essential role of microbial communities in a diversity of environments.
“We’re recognizing that the biosphere is run by microbes at every level,” notes UW-Madison Professor of Medical Microbiology and Im... Read More
The influenza virus particle is made up of the viral RNA genome wrapped in a lipid membrane (illustrated). The membrane, or envelope, contains three different kinds of viral proteins. The hemagglutinin molecule (HA, blue) attaches to cell receptors and initiates the process of virus entry into c... Read More
I saw today in the New York Times that a hookworm vaccine will be tested in Gabon. I found this very intriguing as your discussions of parasitic worms have rarely included the possibility of vaccines. Can you please c... Read More
Reticuloendotheliosis viruses (REVs) are retroviruses that cause a rare disease of gamebirds and waterfowl that includes anemia, immunosuppression, neoplasia, runting, and abnormal feathering. Since the first isolation of REV from a turkey in 1957, REVs were believed to be strictly avian viruses... Read More
By unleashing a genetically modified virus onto microscopic electrode wires, researchers from MIT have shown that the performance of lithium-air batteries can be significantly improved -- a remarkable breakthrough that could revolutionize the way our electric devices are powered.
Indeed, lith... Read More
Two weeks into the government shutdown, flu season is about to ramp up. And without full-scale infectious-disease surveillance by the Centers for Disease Control and Prevention, experts said, health consequences for the nation could range from unsettling to disastrous.
Normally, the CDC monit... Read More
Once upon a time, not too terribly long ago, getting the chicken pox was practically a rite of passage for kids.
But now, nearly 20 years after approval of a vaccine for the varicella virus, which causes the itchy illness, chicken pox is a rarity. A new study conducted by researchers at Kaise... Read More
Microbiology, we will agree, is a vast subject where many important aspects are likely to evade one’s sight. Here’s an example—the formation of vesicles from the outer membrane of Gram-negative bacteria. This phenomenon, known as vesiculation, is widespread and noteworthy for enhancing our under...

Microbes are everywhere – thousands of species are in your mouth, and thousands are in a glass of tap water. The ones in your mouth are mostly harmless – as long as you brush and floss so they don't form a biofilm that allows gum disease a path into the blood stream.
Microbes in the tap water... Read More

The immune system has the capacity to "remember" particular viruses and store those details in B memory cells that reside in the lungs to help ward off future infections. But a new study shows the flu virus takes advantage of this and uses the way the memory cells store its details to recognize ... Read More
Dr. Naowarat Cheeptham, is a famous cave microbiologist. Dr. Cheeptham has been fascinated with the world of biology since she was out catching butterflies as a child with her father in her native country, Thailand. Her interest in microbiology developed while studying at Chiang Mai University ... Read More
When headed the wrong way, some bacteria turn by letting their propellers flop.
The newly discovered turning mechanism explains how a marine bacterium can control its direction using only a single flagellum, a stiff, rotating appendage that propels the cell forward. Turning depends on a mecha... Read More
After spending months working on a series of stories about the trillions of friendly microbes that live in and on our bodies, I decided it might be interesting to explore my own microbiome.
So I pulled out my credit card and paid the $99 needed to sign up for the American Gut Project, one of ... Read More
Members of the legume family of plants (e.g. peas, soybean) can form symbioses with nitrogen-fixing bacteria known as rhizobia. In return for receiving nitrogen-containing compounds (e.g. ammonia) from the rhizobia, the plant supplies the rhizobia with sugars and a home in special organs in the ... Read More
A woman who tested positive for hepatitis C after potentially coming into contact with a hospital worker who had the virus is worried she infected her family.
Angela Richards, from Caerphilly, has been told the virus is no longer present and it could not be confirmed whether she had been infe... Read More
The stability of Middle East respiratory syndrome coronavirus (MERS-CoV) was determined at 20°C – 40% relative humidity (RH); 30°C – 30% RH and 30°C – 80% RH. MERS-CoV was more stable at low temperature/low humidity conditions and could still be recovered after 48 hours. During aerosolisation of... Read More
Young children and the elderly are especially susceptible to respiratory syncytial virus (RSV). The three-dimensional structure of respiratory syncytial virus has been solved by an international team from Finland and Switzerland.
RSV is a common cause of respiratory infection, but there is no... Read More
A team of researchers from McMaster and the University of Concepción are shining a light on rare sulfur-loving microbes off the coast of Chile.
The group's work near coastal fault lines has identified a previously unknown type of molecule, macplocimine A, which produces valuable natural chemi... Read More
