Is it possible that our personal hygiene routines make us too clean? Are we soaping and cleansing away friendly microbes that help preserve skin health? A study presented at the 5th American Society for Microbiology Conference on Beneficial Microbes in Washington, DC, provides food for thought o... Read More
U.S. researchers have found a link between intestinal bacteria and the effectiveness of the flu vaccine. And the finding could have important implications for how vaccines are given.
Our intestines are full of bacteria; they help us digest our food. But scientists are starting to learn how im... Read More
A parasitic fungus that must kill its ant hosts outside their nest to reproduce and transmit its infection, manipulates its victims to die in the vicinity of the colony, ensuring a constant supply of potential new hosts, according to researchers at Penn State and colleagues at Brazil's Federal U...

Experiments with the most dangerous human viruses, such as Ebola virus and Lassa virus, are carried out in biosafety level 4 (BSL-4) laboratories. Since visiting the Northeast Infectious Diseases Laboratory BSL-4 and releasing the documentary video Threading the NEIDL, I was given the opportunit... Read More
Researchers from the Institute of Microbiology at ETH Zurich have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. Researchers are now exploring the various potential applications.
Microbiologists and molecular biologists at ETH Zurich and the Univer... Read More
Drug-resistant bacteria annually sicken 2 million Americans and kill at least 23,000. A driving force behind this growing public health threat is the ability of bacteria to share genes that provide antibiotic resistance.
Bacteria that naturally live in the soil have a vast collection of gene... Read More
A highly anticipated test of an experimental Ebola vaccine will begin this week at the National Institutes of Health, amid mounting anxiety about the spread of the deadly virus in West Africa.
After an expedited review by the U.S. Food and Drug Administration, researchers were given the green... Read More
Treating dairy cows and other farm animals with antibiotics and then laying their manure in soil can cause the bacteria in the dirt to grow resistant to the drugs. But a study now suggests that the manure itself could be contributing to resistance, even when it comes from cows that are free of a... Read More
A powerful genome editing tool may soon become even more powerful. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) have unlocked the key to how bacteria are able to “steal” genetic information from viruses and other foreign invaders for use in their own immunological me...

On Friday afternoon, the federal Centers for Disease Control and Prevention posted a guide explaining how hospitals should manage Ebola patients. Hospital workers entering a patient's room should wear:
- Gown (fluid resistant or impermeable)
- Eye protection (goggles or face shield... Read More
As the West African epidemic of Ebola virus grows, so does misinformation about the virus, particularly how it is transmitted from person to person. Ebola virus is transmitted from human to human by close contact with infected patients and virus-containing body fluids. It does not spread among h... Read More
A new study clarifies how Group A Streptococcus (strep) bacteria resist the human immune system.
The research could eventually lead to the development of a safe vaccine against strep throat, necrotising fasciitis (flesh-eating disease), and rheumatic heart disease.
Previous efforts to deve... Read More
Bear Grylls, that intrepid survival expert from "Man vs. Wild," might want to rethink his penchant for drinking his own urine. Contrary to popular belief, new research shows that urine from an otherwise healthy person may not be as germ-free as we were led to believe.
“For years, actually for... Read More
In a world first, researchers have found that a naturally occurring chemical attracts pregnant malaria-transmitting mosquitoes - a discovery which could boost malaria control efforts. The chemical, cedrol, found in mosquito breeding sites near Africa's Lake Victoria, could be used in traps that... Read More
These days, the happiest place on Earth isn't so cheerful. In December, a large number of people started coming down with measles after visiting Disneyland in California. So far, about 80 measles cases have been reported in the state, an unusually large number for a virus that has long been unde... Read More
For possibly billions of years, the DNA blueprints for life on Earth have been written with just four genetic "letters" -- A, T, G and C. On Wednesday, scientists announced that that they added two more.
In a paper published in the journal Nature, bio-engineers at Scripps Research Institute i... Read More
A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science showed that iron-rich Saharan dust provides the nutrients necessary for specialized bacteria to pr...
