Virulence, the capacity to cause disease, varies markedly among viruses. Some viruses cause lethal disease while others do not. For example, nearly all humans infected with rabies virus develop a disease of the central nervous system which ultimately leads to death. In contrast, most humans are ... Read More
A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Serratia marcescens is a bacteria that has earned a bad reputation for infecting people in hospitals. It may deserve an even worse reputation. It might have made people believe, for hundreds of years, that the blood of Christ was miraculously appearing in communion wafers.
Serratia marcescens... Read More
Influenza viruses evolve rapidly, making it hard to develop protective vaccines against them. Despite a great deal of effort, scientists have found it difficult to forecast which way the virus’ evolution would take it. Now, thanks to improvements in our ability to study viruses and a new mathema... Read More
Scientists have known for years that together, bacteria and plants can remediate contaminated sites. Ramakrishna Wusirika, of Michigan Technological University, has determined that how you add bacteria to the mix can make a big difference. Wusirika has also shed light on the biochemical pathways...

Public health officials issued a warning Thursday that thousands of Bay Area residents were potentially exposed to measles last week when a UC Berkeley student with the virus attended classes in Berkeley and rode on BART.
The student, a Contra Costa County resident whose name was not released... Read More
Doctors have used gene therapy to upgrade the immune system of 12 patients with HIV to help shield them from the virus's onslaught. It raises the prospect of patients no longer needing to take daily medication to control their infection. The patients' white blood cells were taken out of the body... Read More
Communication is vital to any successful relationship. Researchers from the Institute of Food Research and the University of East Anglia have discovered how the beneficial bacteria in our guts communicate with our own cells.
This is a key step in understanding how our bodies maintain a close ... Read More
In a first-of-its-kind study for Lyme disease, researchers have used live, disease-free ticks to see if Lyme disease bacteria can be detected in people who continue to experience symptoms such as fatigue or arthritis after completing antibiotic therapy. The technique, called xenodiagnosis, attem... Read More
After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned a thing or two.
He's learned that naturalist Charles Darwin was wrong about some things. For one, evolution doesn't always occur in steps so slow and steady that changes can't be observed.
Lenski also lea... Read More
Invasive species aren’t just species—they can also be pathogens. Such is the case with the West Nile virus. A mosquito-borne virus identified in the West Nile subregion in Uganda in 1937—hence the name—West Nile wasn’t much of a concern to people elsewhere until it broke out of Africa in 1999. T...

Watch highlights from the Cultures Magazine Launch Event held on January 23, 2014 at American Society for Microbiology headquarters in Washington, D.C.
Scientists have deciphered the 3-D structure of a protein that confers antibiotic resistance from one of the most worrisome disease agents: a strain of bacteria called methicillin-resistant Staphylococcus aureus (MRSA), which can cause skin and other infections. The team's findings may be an imp... Read More
The rise of drug-resistant bacteria and other biological threats has pushed the Pentagon to seek help developing small molecules that can stop some of the world's most dangerous pathogens.
The Defense Threat Reduction Agency, which seeks ways to stop or limit the effects of weapons of mass de... Read More
When a clear sunny day turns into clouds, people used it to explain their grave mood without taking into consideration how clouds can affect global warming in the atmosphere. But University of Georgia marine researchers have discovered the process of an anti-greenhouse gas known as DMSP (dimethy... Read More
This is an accurate visualization of the Bacteriophage T4 based on Cryo-EM datasets of the virus. The scope of the animation is to show the infection process of the T4 into an E. coli cell. All scientific data sets and motion based off of research from Michael Rossmann Laboratory (Purdue Univers... Read More
When confronted with a new bacteria there are a series of simple tests that can be carried out to give a rough idea of the properties of the bacteria you are dealing with. One of the simplest and most useful tests is known as “Gram staining” which is a process of staining cells either purple or ... Read More
Tularemia is endemic in the northeastern United States, and is considered to be a risk to biosecurity -- much like anthrax or smallpox -- because it has already been weaponized in various regions of the world.
At the 58th Annual Biophysical Society Meeting, which started Saturday and continue... Read More
Influenza is killing more young and middle-aged adults this year than usual, in part because they’re less likely to be vaccinated, federal health officials said Thursday.
More than 60 percent of those killed or put into the hospital by flu so far this season have been aged 18 to 64, the Cente... Read More
