Study: Salad Ingredient Kills Drug-Resistant TB

One of the world's oldest known disinfectants – and favorite salad dressings – may prove even stronger than previously thought.

An international research team has found that vinegar – or, more specifically, the active ingredient in vinegar – can kill mycobacteria, including a highly drug-resi... Read More

MERS Virus Widespread in Saudi Arabian Camels (News Release)

The coronavirus responsible for Middle East Respiratory Syndrome (MERS) is prevalent in camels throughout Saudi Arabia and has been around for at least 20 years, according to a study to be published in mBio®, the online open-access journal of the American Society for Microbiology.

“Our study ... Read More

Ice Nucleation Bacteria, Twitter, and Me!

In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More

Scientists unlock a ‘microbial Pompeii’

An international team of researchers including scientists from the University of York have discovered a ‘microbial Pompeii’ preserved on the teeth of skeletons around 1,000 years old.

The key to the discovery is the dental calculus (plaque) which preserves bacteria and microscopic particles o... Read More

Evolution Made Easy, Courtesy of E. Coli (blog)

Evolution is one of those enigmatic subjects we simply do not understand fully. We know it is a biological change at the genetic level that changes the overall nature of an organism. We're also sure that it requires a significant number of generations. Unfortunately, that means it is difficult t... Read More

Video of virus-sized particle trying to enter cell

Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nan... Read More

Deadly MERS Virus Circulates Among Arabian Camels

Scientists have gotten close to pinning down the origin of Middle East Respiratory Syndrome, a dangerous respiratory disease that emerged in Saudi Arabia 17 months ago.

It turns out the MERS virus has been circulating in Arabian camels for more than two decades, scientists report in a study p... Read More

Vinegar kills tuberculosis and other mycobacteria (press release)

The active ingredient in vinegar, acetic acid, can effectively kill mycobacteria, even highly drug-resistant Mycobacterium tuberculosis, an international team of researchers from Venezuela, France, and the US reports in mBio®, the online open-access journal of the American Society for Microbiolo...

On Finding Jewels in the Junk

In prokaryotes, it only takes a small jazz band to get the music grooving: piano and a rhythm section suffice. The promoter region of a gene is a tiny stage on which RNA polymerase (p) and few transcription factors (dr, b) improvise on a tune, i.e. they initiate or skip transcription. By contras... Read More

Does medicine really need lab mice?

Using animals to test drugs destined for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary.

It is estimated that in the UK around three million mi... Read More

Professor doesn’t overlook the small things in biology

Frog-killing fungi, the methods bacteria use to evade antibiotics, and the hidden microbes deep inside an Antarctic lake: These are just a few of the topics covered in “Small Things Considered,” a microbiology blog run by Moselio Schaechter. Schaechter is former president of the American Society... Read More

Progress Against Hepatitis C, a Sneaky Virus

Forty years ago, a beloved neighbor was bedridden for weeks at a time with a mysterious ailment. She knew only that it involved her liver and that she must never drink alcohol, which would make things worse.

It was decades before the cause of these debilitating flare-ups was discovered: a vir... Read More

CDC: 1 dead, 7 others sickened by listeria traced to cheese

At least eight people came down with listeria -- and one of them died -- after, authorities believe, eating "Hispanic-style cheese."

The Centers for Disease Control and Prevention on Friday reported the outbreak, which has affected people only of Hispanic descent and living in California or M... Read More

From the archives: life at 90°C

Prokaryotes are by far the most successful superkingdom in terms of both biochemical diversity and the variety of environments conquered. Bacteria can be found living in all kinds of adverse conditions; from high alkaline lakes, to below freezing temperature, to hot volcanic vents which in some ... Read More

Researchers find that going with the flow makes bacteria stick

In a surprising new finding, researchers have discovered that bacterial movement is impeded in flowing water, enhancing the likelihood that the microbes will attach to surfaces. The new work could have implications for the study of marine ecosystems, and for our understanding of how infections t... Read More

Rare 'polio-like' disease reports

US doctors are warning of an emerging polio-like disease in California where up to 20 people have been infected.

A meeting of the American Academy of Neurology heard that some patients had developed paralysis in all four limbs, which had not improved with treatment.

The US is polio-free, b... Read More

What’s Vibrio Fischeri? Why, Possibly the State Microbe!

Hawaii Senate Bill 3124 would make Vibrio fischeri the official state microbe.

Here’s why, according to the bill:

Vibrio fischeri is deserving of being Hawaii’s official state microbe because of its broad reputation as among the best-studied beneficial microbes. These bacteria live in... Read More

How a Microbe Resists its Own Antibiotics

In the mid-2000s, scientists identified two novel antimicrobial compounds in the bacterium Streptomyces platensis, each of which target a different enzyme involved in fatty acid synthesis in other microbes. Platensimycin and platencin are now being explored as a new class of antibiotics. Researc... Read More
