Hunting pack of bacteria paints a tangled skein

Bacteria that glide together… make art together? This contender in the Art of Science competition run by Princeton University in New Jersey, entitled The history of gliding, depicts the squiggly gliding paths of the bacteria Myxococcus xanthus.

M. xanthus are social bacteria that move in coor... Read More

Resistance to last-line antibiotic also makes bacteria resistant to immune attacks

Bacterial resistance to antibiotics is bad enough, but what if drug resistance also gives bacteria the ability to fend off attacks by the immune system? In a study in mBio this week scientists identify a lose-lose situation with colistin and Acinetobacter baumannii: bacteria resistant to colisti... Read More

Some of My Best Friends Are Germs

I can tell you the exact date that I began to think of myself in the first-person plural — as a superorganism, that is, rather than a plain old individual human being. It happened on March 7. That’s when I opened my e-mail to find a huge, processor-choking file of charts and raw data from a labo... Read More

Behind the Cover Story: Michael Pollan on Why Bacteria Aren’t the Enemy

Michael Pollan, food author, activist and journalism professor, wrote this week’s cover story about the organisms with which we share our bodies — and how we’re dependent on them. His book “Cooked: A Natural History of Transformation” came out last month. His last article for the magazine was ab... Read More

Genome Sequencing Provides Unprecedented Insight Into Causes of Pneumococcal Disease

A new study led by researchers from Harvard School of Public Health (HSPH) and the Wellcome Trust Sanger Institute in the UK has, for the first time, used genome sequencing technology to track the changes in a bacterial population following the introduction of a vaccine. The study follows how th... Read More

Resistance to Visceral Leishmaniasis: New Mechanisms Involved

Researchers from CNRS, Université Toulouse III -- Paul Sabatier and IRD have elucidated new molecular mechanisms involved in resistance to visceral leishmaniasis, a serious parasitic infection. They have shown that dectin-1 and mannose receptors participate in the protection against the parasite... Read More

Food Laboratory Accuracy Remains A Concern

Food microbiology laboratories continue to submit false negative results and false positive results on a routine basis. A retrospective study of nearly 40,000 proficiency test results over the past 14 years, presented today at the 113th General Meeting of the American Society for Microbiology, ... Read More

Inefficient influenza H7N9 virus aerosol transmission among ferrets

There have been 131 confirmed human infections with avian influenza H7N9 virus in China, but so far there is little evidence for human to human transmission. Three out of four patients report exposure to animals, ‘mostly chickens‘, suggesting that most of the infections are zoonoses. Whether or ... Read More

Biosensor That Detects Antibiotic Resistance Brings Us One Step Closer to Fighting Superbugs

On May 8th JoVE will publish research that demonstrates how a biosensor can detect antibiotic resistance in bacteria. This new technology is a preliminary step in identifying and fighting superbugs, a major public health concern that has led to more deaths than AIDS in the United States in recen... Read More

Study: Handbags May Have More Bacteria Than A Toilet Seat

Many ladies love their handbags and will spend a lot of money for the latest and greatest, but a new study says what is inside those bags may be covered in germs worse than what you’ll find in the bathroom.

As CBS 2′s Cindy Hsu reported Wednesday, the study said your purse may, in fact, have ... Read More

Thymus Teaches Immune Cells to Ignore Vital Gut Bacteria

The tiny thymus teaches the immune system to ignore the teeming, foreign bacteria in the gut that helps you digest and absorb food, researchers say.

When immune cells recognize essential gut bacteria as foreign, inflammatory bowel disease such as ulcerative colitis and Crohn's disease can be ... Read More

TWiP 54 Letters

Tommy writes:


Hi Vincent and Dickson,


I was listening to the new episode of TWiP (episode 52) and one of your listeners wrote in asking about tree parasites. While plant parasite is not my main field of research, I have written about one such pa... Read More

Now We Know Why Old Scizophrenia Medicine Works On Antibiotics-Resistant Bacteria

In 2008 researchers from the University of Southern Denmark showed that the drug thioridazine, which has previously been used to treat schizophrenia, is also a powerful weapon against antibiotic-resistant bacteria such as staphylococci (Staphylococcus aureus).

Antibiotic-resistant bacteria is... Read More

Clawed frogs spread deadly amphibian fungus

The African clawed frog, a species used around the world for biomedical research, is spreading an amphibian-killing fungus when they are released into the wild. In a new study, researchers provide the first evidence that the frogs in California harbor a fungal infection that is decimating amphib... Read More
