The disruption of the human microbiome through use of antimicrobials is a topic of growing interest among healthcare epidemiologists, not only because it is a major risk factor for C. difficile infection (CDI), but also because it could be a driving force behind the introduction and proliferatio...

Scientists were able to reliably predict the timing of the 2012-2013 influenza season up to nine weeks in advance of its peak. The first large-scale demonstration of the flu forecasting system by scientists at Columbia University’s Mailman School of Public Health was carried out in 108 cities ac... Read More
Like pretty much all multi-cellular organisms, humans enjoy the benefits of helpful bacteria. (As you may have heard, there are more bacteria in the human body than cells.) These mutualistic microbes live within the body of a larger organism, and, like any good long-term houseguest, help out the... Read More
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
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...

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
ASM Global Video Challenge submission!
Hello ASM! I am a microbiology graduate student in the Runstadler Lab at MIT. We are an interdisciplinary group of scientists comprising biochemists, ecologists, computer scientists, veterinarians, and microbiologists. Together, our lab studies all aspec... Read More
This episode: Bacteria with engineered circuits can detect and keep a record of stuff in their environment, like in the gut!

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
For my medical microbiology course at Kutztown University of Pennsylvania we were asked to take a sample from our nose. Using a sterile cotton swab, a sample was taken from a nostril and then spread onto the Mannitol Salt Agar plate supplied. The plate was incubated at 37 degrees Celsius, then e... Read More
This episode: Interview with Jordi van Gestel: cheaters in bacterial communities don't always succeed!

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
The TWiV team reviews the discovery of old vials of smallpox virus at NIH, anthrax and influenza mishaps at CDC, the baby who was not cured of HIV, Cambridge Working Group, and sacking of NSABB members.

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
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
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
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
