What Is Vibrio Vulnificus? Flesh-Eating Salt Water Bacteria Infects 31 In Florida

Florida health officials are encouraging the state’s residents not to be alarmed following another death from the flesh-eating bacteria Vibrio vulnificus. The rare bacteria that thrives in saltwater has killed 10 people in Florida this year, while 31 people in all have been infected with the ... Read More

Curious about the Human Microbiome?

The American Academy of Microbiology has released its newest report on the human microbiome. Based on the deliberations of some of the leading experts, the report answers common questions people have about this new field of science. While there is still much to be learned, this report presents t... Read More

Clever microbes: bacterial sensors and signals

Exploring signalling systems is often a multidisciplinary process, requiring genetic research, mathematical modelling and evolutionary biology. A recent paper looking at the bacterial phage shock response uses all of these approaches to build up a picture of the complete signalling system.

I listened to the latest TWIP this morning. Dickson mentioned the herbicide atrazine but thought it was a fungicide. It is actually a herbicide in the photosynthesis inhibitor class. Another bit of trivia about ag chemicals is that old chemicals like ... Read More

Parents' Saliva On Pacifiers Could Ward Off Baby's Allergies

That word "microbiome" — describing the collection of bacteria that live in and on our bodies — keeps popping up. This time, researchers say that children whose parents clean their pacifiers by sucking them might be less likely to develop allergic conditions because of how their parents' saliva ... Read More

Antimicrobial from soaps promotes bacteria buildup in human noses

An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their fi... Read More

New test system identifies 193 different yeasts and bacteria known to cause illness (FDA Press Release)

The U.S. Food and Drug Administration today allowed marketing in the U.S. of the first mass spectrometer system for automated identification of bacteria and yeasts that are known to cause serious illness in humans. The VITEK MS can identify 193 different microorganisms and can perform up to 192 ... Read More

BacterioFiles Micro Edition 146 - Engineered Escherichia Eliminates Enemies

This episode: Scientists engineered E. coli to seek and destroy pathogens!


(10 MB, 11 minutes)


A bacterium can sense pathogens in the body, swim toward them, and release a deadly biofilm-busting payload. This process is called pseudotaxis, and could be modified for many... Read More

Two new weapons in the battle against bacteria

Proteases are vital proteins that serve for order within cells. They break apart other proteins, ensuring that these are properly synthesized and decomposed. Proteases are also responsible for the pathogenic effects of many kinds of bacteria. Now chemists at the Technische Universitaet Muenchen ... Read More

CDC prepares for potential outbreak of deadly MERS virus

As the deadly MERS virus continues to infect people throughout the Middle East and Europe, the Centers for Disease Control and Prevention (CDC) has begun to prepare for the disease’s potential spread to the United States.
Currently, the U.S. has had no confirmed cases of the MERS virus, a respi... Read More

Thanks to Rare Alpine Bacteria, Researchers Identify One of Alcohol’s Key Gateways to the Brain

Thanks to a rare bacteria that grows only on rocks in the Swiss Alps, researchers at The University of Texas at Austin and the Pasteur Institute in France have been the first to identify how alcohol might affect key brain proteins.

It’s a major step on the road to eventually developing drugs ... Read More

New Drugs Use Cell "Garbage Disposal" to Kill Bacteria

A new class of molecules called acyldepsipeptides—ADEPs—may provide a new way to attack bacteria that have developed resistance to antibiotics.

Researchers have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemica... Read More

Mysterious Microscopic Bubbles Baffle Ocean Scientists

The most abundant photosynthetic organism in the world sheds countless little sacs into the oceans, which could be having a dramatic impact on marine ecosystems, according to a new study. These microbial buds contain proteins and genetic material, which may influence the growth of other marine m... Read More

Bacteria Turn Plants and Insects into Zombies

Many parasites commandeer the bodies of their hosts in order to spread. Examples of this include horsehair worms that reach water by forcing their cricket hosts to drown themselves, and liver flukes that drive infected ants to climb blades of grass, where cows can eat the insects, and so the flu...

India has been free of polio for three years

Three years ago today, on 13 January 2011, the last case of poliomyelitis was reported in India. This achievement represents a remarkable turnaround for a country where control of the disease had for years been extremely difficult. As recently as 2009 there were 741 confirmed cases of polio caus... Read More

Discovery opens up new areas of microbiology, evolutionary biology

A team of researchers led by Virginia Tech and University of California, Berkeley, scientists has discovered that a regulatory process that turns on photosynthesis in plants at daybreak likely developed on Earth in ancient microbes 2.5 billion years ago, long before oxygen became available.

Hi Vincent and Dickson,


I enjoy TWIP, and often recommend it to my students. I'm a parasitologist, primarily a Leishmaniac, but I have learnt a lot from TWIP. I find it both more educational and entertaining than Car Talk.
