The vaccine used to protect against tuberculosis disease, bacillus calmette-guerin or BCG, also protects against tuberculosis infection, mycobacterium, as well as protecting against progression from infection to disease, finds new research. The BCG vaccine has been subject to numerous trials and... Read More
We need fungal Solutions to Pollution, Global Pandemics, and Starvation, says Tradd Cotter, a microbiologist and professional mycologist.
I have been studying mushrooms, inside and out, macroscopically and microscopically, for the past 22 years. At times I imagine myself deep into their chemi... Read More
Human norovirus may infect our canine companions, according to research published online April 1 in the Journal of Clinical Microbiology, a publication of the American Society for Microbiology. That raises the possibility of dog-to-human transmission, said first author Sarah Caddy, VetMB, PhD, M... Read More
Scientists at the University of Western Ontario have uncovered a bacterial mystery. Against all logic, the most predominant strain of methicillin-resistant Staphylococcus aureus (MRSA) in North American produces an enzyme that degrades skin secretions into compounds that are toxic to itself. Th... Read More
In light of the severity and rapid progression of this year's Ebola crisis and the inability of medical workers to combat the virus, a newly developed vaccine has been shown to elicit a strong immune response in over 90% of volunteers in an NIH clinical trial. Volunteers were monitored for sign... Read More
The news in July that HIV had returned in a Mississippi toddler after a two-year treatment-free remission dashed the hopes of clinicians, HIV researchers and the public at large tantalized by the possibility of a cure.
But a new commentary by two leading HIV experts at Johns Hopkins argues th... Read More
What would actually happen if only 80 percent of school-age children were vaccinated against the measles? It’s a scary thought that a new simulation from the University of Pittsburgh aims to visualize.

In the first evidence that natural selection favors an individual's infection tolerance, researchers from Princeton University and the University of Edinburgh have found that an animal's ability to endure an internal parasite strongly influences its reproductive success. Reported in the journal ... Read More
It’s a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents’ DNA.
But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown that the DNA of ba... Read More
For over a century, microbiologists have been using growth media solidified with agar to culture microbes from environmental samples. Individual cells are easily separated on the solid surface, allowing each cell to grow and divide and form a colony of thousands of clones. We can change the nutr... Read More
Researchers at North Carolina State University have for the first time mapped human disease-causing pathogens, dividing the world into a number of regions where similar diseases occur.
The findings show that the world can be separated into seven regions for vectored human diseases – diseases ... Read More
One of the human body’s first responses to a viral infection is to make and release signaling proteins called interferons, which amplify the immune system response to viruses. Over time, many viruses have evolved to undermine interferon’s immune-boosting signal, and a new study describes a mecha... Read More
A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria.
A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. The study was conducted by researchers from the U.S. Departm... Read More
After studying 137 varieties of cheese collected in 10 different countries, researchers have been able to identify three general types of microbial communities that live on cheese, opening the door to using each as a 'model' community for the study of whether and how various microbes and fungi c...

The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide. And scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to promote rapid evolution un... Read More
The tropical disease chikungunya began twisting Western tongues in July when the first locally transmitted case was reported in Florida. Spotted in the Caribbean just last year, the disease spread explosively throughout the Americas in 2014. Chikungunya's arrival in Panama prompted Smithsonian s... Read More
Living deep underground ain't easy. In addition to hellish temperatures and pressures, there's not a lot to eat. Which is why oil reservoirs are the microbes’ cornucopia in this hidden realm.
Microbes feast on many oil reservoirs, but it has been unclear how the micro-organisms got to those ... Read More
Our bodies and homes are covered in microbes -- some good for us, some bad for us, and some just along for the ride. As we learn more about the germs and microbes who share our living spaces, TED Fellow Jessica Green asks: Can we design buildings that encourage happy, healthy microbial environme... Read More
For the first time, Spanish researchers have detected an unknown interaction between microorganisms and salt. When Escherichia coli cells are introduced into a droplet of salt water and is left to dry, bacteria manipulate the sodium chloride crystallisation to create biomineralogical biosaline 3... Read More
