The science behind the transformation from plants to milk to cheese is amazing. In fact, cheese has much in common with wine and beer: They result from fermentation by microorganisms; they are “value-added” products where processing greatly increases the value; and they reflect local climate and...

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
Vincent and friends,
While driving around a field cutting hay lost in my science podcast playlist the episode of TWIM #61 came up and I had to listen intently as salmonella typhimurium came up as this is a common enteric issue in agriculture. When ... Read More
Ten years ago this month I wrote the first post at virology blog, entitled Are viruses living? Thanks to EE Giorgi for pointing out the ten year anniversary, and also for publishing an interview with me at her blog, Chimeras. Here is how this blog got started. Read More

The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-t... Read More
Brucellosis is a worldwide extended infectious disease of livestock (sheep, goats, cattle, cows, pigs, …) and remains one of the most common zoonotic infections, with more tan 500,000 new human cases worldwide every year. Control and eradication of brucellosis requires the use of animal vaccines... Read More
Thousands of deaths from tuberculosis (or TB), an infectious bacterial disease, could be prevented using a new hand-held device that is being developed to detect potentially fatal drug resistance in less than 15 minutes.
Currently neither the TB infection itself, nor those people with strains... Read More
In recent years, scientists have found out all sorts of remarkable things about a group of creatures that are entirely invisible to the naked eye: the trillions of bacteria that colonize every surface of our bodies.
These organisms—collectively known as the microbiome—deeply affect our health... Read More
During the April 2013 avian influenza A (H7N9) outbreak, more than 130 human infections with H7N9 were reported. Most patients had severe respiratory illness and 44 people have died. Studies suggest that the H7N9 virus has developed resistance to oseltamivir. A human interferon already in use fo... Read More
It's natural to expect that the water coming out of our taps is safe without worry of gastrointestinal or other infectious disease. Yet every year there are dozens of outbreaks linked to drinking water in the United States alone. In the majority of cases, a failure of proper water treatment is t... Read More
Vincent meets up with XJ Meng and Sarah McDonald at Virginia Tech in Blacksburg to talk about their work on viruses of swine and rotaviruses.
Host: Vincent Racaniello

For people in too many developing countries, clean water is often a luxury. Chlorine treatments are too expensive for small villages, boiling requires a hefty investment in fuel, and UV radiation demands regular high-tech maintenance. But now, scientists say that a simple, inexpensive water filt... Read More
It seems that nearly every day, scientists connect another medical condition to atypical gut bacteria populations. Researchers have claimed that gut bacteria play a role not just in digestive health but even in basic brain function and mental health. Certain bacteria are so clearly good for us t... Read More
Dear water-based life forms:
It is 24 degrees in Overland Park, Kansas and I am looking at a slide labeled "Giardia lamblia", part of a museum exhibit on water and human (over) use of water.
I see a greenish lump. I don't know... Read More
After having listened to your discussions on Plasmodium (TWiP 64), I explored papers on treatment options that are actually available. After having read some papers, I realized that one of the main roadblocks are the hypnozoite... Read More
Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.
“This clearly shows that there is an association between oral bacte... Read More
Underground in places nobody likes to look, bacteria are doing terrible things to our sewage pipes. The concrete pipes that carry our waste are literally dissolving away, forcing engineers into a messy, expensive battle against tiny microbes.
"The veins of our cities are in serious trouble, a... Read More
