Using tobacco to thwart West Nile virus

An international research group led by Arizona State University professor Qiang "Shawn" Chen has developed a new generation of potentially safer and more cost-effective therapeutics against West Nile virus, and other pathogens. The therapeutics, known as monoclonal antibodies (MAbs) and their de... Read More

Researchers Identify Protein That Helps Control Common Viral Infection

Infectious disease specialists at the Johns Hopkins Children’s Center have identified a protein that regulates the body’s immune response to cytomegalovirus (CMV), a common pathogen that causes lifelong infections and can lead to devastating illness in newborns and those with weakened immune sys...

Pathogens in Cheese – Researchers Follow the Traces of Deadly Bacteria

If food products are not produced in a hygienic environment, consumers can face the threat of dangerous pathogens. This is exactly what happened in 2009 and 2010 when two different strains of Listeria monocytogenes were found in the traditional Austrian curd cheese known as “Quargel”. 34 people ... Read More

Rotavirus Activates Lymphocytes from Non-Obese Diabetic Mice by Triggering Toll-Like Receptor 7 Signaling and Interferon Production in Plasmacytoid Dendritic Cells

It has been proposed that rotavirus infection promotes the progression of genetically-predisposed children to type 1 diabetes, a chronic autoimmune disease marked by infiltration of activated lymphocytes into pancreatic islets. Non-obese diabetic (NOD) mice provide a model for the human disease.... Read More

Oral Bacteria and Cancer

Over a number of years, epidemiological studies established several well-defined risk factors for cancer, including age, heredity, diet, tobacco use, chronic viral infections, and inflammation. Paradoxically, the success of these studies left little room for incorporation of any new factors or c... Read More

Engineered Bacteria Produce Biofuel Alternative for High-Energy Rocket Fuel

Researchers at the Georgia Institute of Technology and the Joint BioEnergy Institute have engineered a bacterium to synthesize pinene, a hydrocarbon produced by trees that could potentially replace high-energy fuels, such as JP-10, in missiles and other aerospace applications. With improvements ... Read More

Resistance is Not Futile: Joint BioEnergy Institute Researchers Engineer Resistance to Ionic Liquids in Biofuel Microbes

Researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI), a multi-institutional partnership led by Berkeley Lab, have identified the genetic origins of a microbial resistance to ionic liquids and successfully introduced this resistance into a strain of E. coli bact...

Popular probiotics have few cons, experts say

Every year, half of all Americans take some kind of pill as insurance against their diets.

But recently, researchers have noticed a surprising trend: Use of some of the most popular supplements is waning, possibly because of recent reports questioning their benefits and raising awareness abou... Read More

Fauci: Robust Research Efforts Needed to Address Ongoing, Global Challenge of Antimicrobial Resistance

Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More

Scientists build man-made 'living-materials' inside bacterial cells

Our bones are remarkable feats of engineering; strong and yet light, shot through with holes and yet able to bear incredible loads. This super-strong natural material is built as cells incorporate hard minerals like calcium into living tissue. Now, scientists at the Massachusetts Institute of Te... Read More

Five new Listeria species found; may improve tests

Cornell researchers have discovered five new species of a group of bacteria called Listeria – including one named for Cornell – that provide new insights that could lead to better ways to detect soil bacteria in food. To date, of the 10 previously known species of Listeria, only two are pathogen... Read More

Twenty-six lectures in virology

In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.

You can find my virology lect... Read More

1 in 25 patients gets infection in hospital

When antibiotics first started being used in the 1940's they were considered a "miracle drug". It seemed that bacterial infections would no longer be a problem for the world. However, recently, one gene is making it seem as though the end of antibiotics is at hand. This gene is New Delhi metallo... Read More

Resurrecting ancient microbes to understand evolution

When you hear the word “resurrection”, what’s the first thing that comes to mind? Religious miracles? Zombie viruses? The end of the world?

Whatever your mental association, I’m willing to bet it’s not “an emerging scientific discipline." Well, it just so happens a growing community of microb... Read More

One in 25 patients battling hospital-acquired infections: CDC

On any given day, one in 25 hospitalized patients - 4 percent - is battling an infection picked up in a hospital or other healthcare facility, according to a new survey by the Centers for Disease Control and Prevention (CDC).

That translates to more than 600,000 hospital patients each year. R... Read More

Environmental Swab/Bottom of Shoe #2

Close up view of the edges of an unknown bacteria swabbed form the bottom of a shoe, possible Bacillus, on TSA exhibiting spreading and rhizoid growth. The pigment is opaque white-beige with a mucoid surface towards the center of the colony and a matte surface towards the edges. Note: transmit... Read More

Environmental Swab/Bottom of Shoe #1

On the first day of Micro class instructors have students do an environmental swab. This sample was subcultured from a student who did the bottom of their shoe. The organism, possible Bacillus sp., was tough to scrap off the agar so subculture was done by taking a small chunk of agar containi... Read More

Airborne Environmental Isolate #3

An unknown airborne environmental isolate on Mueller-Hinton agar exhibiting a single circular colony. White hyphal growth on the outer edges of the mold colony, where spores have not yet developed, surrounding the red/pink grainy spore formation in the center of the colony. This sample grew at ...
