What Happens to Bacteria in Space?

In the otherwise barren space 220 miles above Earth's surface, a capsule of life-sustaining oxygen and water orbits at 17,000 miles per hour. You might know this capsule as the International Space Station (ISS), currently home to six humans—and untold billions of bacteria. Microbes have always f... 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

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

Baker's Yeast Gets a Genetic Makeover

The humble baker's yeast has been enlisted to serve the needs of humanity, responsible for beer, wine and bread, among other staples. A domesticated servant for at least millennia, the microscopic fungus has now had one of its chromosomes swapped out by a host of undergraduate students in favor ... Read More

New probiotic improves pig health, reduces manure output

A new probiotic for pigs could mean less manure to manage, according to U.S. Department of Agriculture (USDA) studies. Agricultural Research Service (ARS) scientists conducted the first published investigation of the use of bacteria as a probiotic to increase fiber fermentation rates and reduce ... Read More

An immune system for Algernon?

I haven't read it (yet) but heard Daniel Keyes' 1960 short story/1966 novel is a sci-fi masterpiece.

And it's the first place my mind went upon reading about this fascinating breakthrough by researchers at Yale. Read More

Stockpiles of Roche Tamiflu drug are waste of money, review finds

Researchers who have fought for years to get full data on Roche's flu medicine Tamiflu said on Thursday that governments who stockpile it are wasting billions of dollars on a drug whose effectiveness is in doubt.

In a review of trial data on Tamiflu, and on GlaxoSmithKline's flu drug Relenza,... 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

Computing with Slime

A future computer might be a lot slimier than the solid silicon devices we have today. In a study published in the journal Materials Today, European researchers reveal details of logic units built using living slime molds, which might act as the building blocks for computing devices and sensors....

Predicting the virulence of MRSA from its genome sequence

Microbial virulence is a complex and often multifactorial phenotype, intricately linked to a pathogen’s evolutionary trajectory. Toxicity, the ability to destroy host cell membranes, and adhesion, the ability to adhere to human tissues, are the major virulence factors of many bacterial pathogens... Read More

Lassa Fever Reported in U.S. Traveler to West Africa

A Minnesota man who returned from a trip to West Africa has been diagnosed with Lassa fever, a severe and sometimes deadly viral disease rarely seen in the United States, health officials said.

The man, who was hospitalized with fever and confusion on March 31, was confirmed to have Lassa fev... Read More

Are tiny microbes outwitting us to steal our food?

It's long been know that microbes are to blame for food going off and becoming rotten but in the late 1970's, Dan Janzen of the University of Pennsylvania, and a winner of ecology's version of the Nobel Prize, suggested that making something rotten may be to the advantage of the microbes living ...

From Geology to Biology: A Serpentine Story of Early Life

Over 4.5 billion years ago, the Earth was a superheated sphere of molten rock, radiating heat to space at over 2000 K. A billion years later, it had global oceans, teeming with microorganisms. In that time, the Earth underwent massive geological changes, somehow serendipitously creating conditio... Read More

Structural insights into inner workings of viral nanomachine

Researchers are using new nanoscale imaging approaches to shed light on the dynamic activities of rotaviruses, important pathogens that cause life-threatening diarrhea in young children. Once a rotavirus enters a host cell, it sheds its outermost protein layer, leaving behind a double-layered pa... Read More

Genetic Defect May Confer Resistance to Certain Viral Infections

A National Institutes of Health (NIH) study reports that a rare genetic disease, while depleting patients of infection-fighting antibodies, may actually protect them from certain severe or recurrent viral infections. Researchers found that HIV and influenza viruses replicate in the cells of peop... Read More

Physarum oblatum

Myxomycetes are well-known as true slime molds whose plasmodia are increadibly beautiful. Plasmodial culture is a such kind of hard-working steps in working with the species of Kingdom Protista. Interestingly, they can unpredictably "move" around water agar dishes. Furthermore, they are in progr... Read More

Phage 'cocktail' wipes out 99 percent of E. coli in meat, spinach

Treating food products with select bacteriophages - viruses that target and kill bacteria - could significantly reduce concentrations of E. coli, a Purdue University study shows.

An injection of bacteriophages - also known informally as "phages" - nearly eradicated a toxin-producing strain of... Read More

Virology question of the week

On the science show This Week in Virology we receive many questions and comments, which are read every week. I also get many questions here on virology blog, which I tend to answer by email. However I think that everyone could benefit from these questions, so I’ve decided to post one here each w... Read More

Researchers find way to reduce E. coli in cows, improving food safety

A new biological treatment could help dairy cattle stave off uterine diseases and eventually may help improve food safety for humans, a University of Florida study shows.

Kwang Cheol Jeong, an assistant professor in animal sciences and UF’s Emerging Pathogens Institute, examined cattle uterin... Read More
