Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research, which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.
Incidence of alle... Read More
A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis.
The function in the algae of this quantum effect, known as coherence, remains a mystery, but it is thoug... Read More
The most abundant photosynthetic organism in the world sheds countless little sacs into the oceans, which could be having a dramatic impact on marine ecosystems, according to a new study. These microbial buds contain proteins and genetic material, which may influence the growth of other marine m... Read More
Tuberculosis (TB) represents a serious public health problem: 8.7 million cases in 2001 and over 1.4 million deaths per year. In 2006, extensively drug-resistant (XDR) tuberculosis has been confirmed in 84 countries, heralding the possibility of virtually untreatable tuberculosis. The emergence ... Read More
Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists at the Technische Universitaet Muenchen ... Read More
Three years ago today, on 13 January 2011, the last case of poliomyelitis was reported in India. This achievement represents a remarkable turnaround for a country where control of the disease had for years been extremely difficult. As recently as 2009 there were 741 confirmed cases of polio caus... Read More
The man arrived at the hospital with a fever and a bad cough. Relatives accompanied him through the doors, beneath the red neon sign reading "Emergency."
It looked like pneumonia, but when doctors at Community Hospital learned that the patient was a healthcare worker in Saudi Arabia, they beg... Read More
Bioengineer Ingmar Riedel-Kruse of Stanford University has created a series of games where players control organic microbes.
The games, which you can see showcased in the video below, places a collection of single-celled protozoans called paramecia in a thumbnail-sized chamber with electrode-... Read More
As many as 75 scientists working in government laboratories may have been exposed to live anthrax bacteria, the Centers for Disease Control and Prevention said on Thursday. The scientists are being offered treatment to prevent infection.
The potential exposure occurred after researchers worki... Read More
B. cereus was grown on urea agar for 6 days at 37 degrees C to induce spore formation.
The endospore stain was done using malachite green as the primary stain and safranin as counter the stain. Malachite green was applied to the smear and set over a steaming water bath for 10 min (stain was no... Read More
A study led by St. Jude Children’s Research Hospital scientists highlights a new approach for developing a universal influenza vaccine that could protect against multiple flu strains, including deadly pandemic strains. The research appears today in the advance online edition of the scientific jo... Read More
Where humans travel, bacteria will follow. If people are in space for any amount of time, bacteria are sure to thrive there so it’s good to know that there are already researchers looking at how the environment within spaceships affects bacterial populations. Work done on planktonic colonies of ... 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
When children are starving, the bacteria that live in their intestines may determine whether they can be saved, scientists working in Bangladesh are reporting. And they say it may become imperative to find a way to give children bacteria as well as food.
The study, done by researchers from Wa... Read More

Streak plate isolation of E. coli on MacConkey Agar grown for 24 hrs at 37 degrees. E. coli demonstrates strong lactose fermentation indicated by the bright pink halo, bile precipitant around the colonies, and pink colony growth. Read More
Buried deep in the mud along the banks of a remote salt lake near Yosemite National Park are colonies of bacteria with an unusual property: they breathe a toxic metal to survive. Researchers from the University of Georgia discovered the bacteria on a recent field expedition to Mono Lake in Calif... Read More
Could a fist bump be a cleaner, better way for people to greet each other, especially in germy hospitals? British researchers have done an experiment that seems to say yes.
They tested just how many bacteria are transferred hand to hand during a handshake, a high-five and a fist bump. Handsha... Read More
