Love the pod cast!
I once went into a very large bookstore and asked the clerk if they had any books on parasitology. She said that they did and pointed in the direction of a large case of colorful books which on closer examination turned out to ... Read More
The emergence of the 2009 pandemic influenza A(H1N1) virus in North America and its subsequent global spread highlights the public health need for early warning of infectious disease outbreaks. Event-based biosurveillance, based on local- and regional-level Internet media reports, is one approac... Read More
In addition to working as a scientist, and well before his discovery of antibiotics, Alexander Fleming painted. He was a member of the Chelsea Arts Club, where he created amateurish watercolors. Less well known is that he also painted in another medium, living organisms. Fleming painted ballerin... Read More
Andrew Dopheide has created an animation that illustrates signaling and quorum sensing.
"A solitary bacterium cannot form a biofilm by itself - it must wait until a group of bacteria has gathered. With no fingers to count on, how do bacteria know when there are enough others nearby? Bacteria ... Read More
Food-handling safety risks at home are more common than you may think. The 4 easy lessons of this Be Foodsafe video are clean, separate, cook and chill. Read More
Bacteria can elaborate complex patterns of development that are dictated by temporally ordered patterns of gene expression, typically under the control of a master regulatory pathway. For some processes, such as biofilm development, regulators that initiate the process have been identified but s... Read More
To take full advantage of recent increased financial commitments from some governments, international agencies, and philanthropies, accurate and up-to-date mapping of neglected tropical diseases (NTDs) needs to be implemented to help improve the precision of decision-making in NTD control and el...

Elio Schaechter of Small Things Considered highlights some of the scientific development that took place centuries ago in Quito, the present-day capital of Ecuador.
"In 1589 a smallpox epidemic killed 37.5% of Quito’s inhabitants. A description of the disease in a letter by one of... Read More
First, you may be asking yourself – Why viral bioinformatics? Good question! Although it’s true that much in the world of bioinformatics can be applied to all manner of protein and DNA sequences, there are a number of resources that are specific for viruses and there are a number of analyses tha...

Merry Youle from the Small Things Considered blog ponders the potential size a virus can be:
"With such fascinating stories being told by Mimivirus and the other giants, people are now looking for them in more environments. Modified techniques are called for, as those used previously to spot ... Read More
Hi Vincent et Al :)
I am an avid listener of both Twiv and Twip and am very grateful that you all take the time each week to create these wonderful podcasts, they are a great learning tool! I did have several questions I’d li... Read More
Vincent, Rich, Karla, and Marilyn recorded TWiV at the 29th Annual Meeting of the American Society for Virology in Bozeman, where they discussed plant viruses and how they make plants resistant to adverse co... Read More
The illustration at left depicts a virion – the infectious particle that is designed for transmission of the nucleic acid genome among hosts or host cells. A virion is not the same as a virus. I define virus as a distinct biological entity with five distinct characteristics. Others believe that ... Read More
Microbe magazine Current Topics and Features Editor Jeff Fox talks with Douglas Theobald of Brandeis University about Theobald's work testing the he notion of a universal common ancestry (UCA) for all species.

Hello Professor Racaniello,
We are two graduate students from the University of Guelph in Canada studying oncogenic sheep betaretroviruses and we are big fans of the show. Part of the reason we like the show so much is that we can use ... Read More
On episode #91 of the podcast This Week in Virology, Vincent, Dickson, Alan, Rich and Welkin discuss the nature, origin, and evolution of endogenous retroviruses (ERVs), and the recent finding of en... Read More
Next generation sequencing is a powerful method increasing in popularity for use in metagenomic and transcriptomic analysis in environmental microbiology. Compared to Sanger sequencing, next generation allows for sequencing of the complete genomic content of a sample without the need to make clo... Read More
Global fish farming may be the solution to the impending collapse of the commercial fishing industry, but penned fish are susceptible to infectious diseases. Infection with salmon infectious anemia virus, an orthomyxovirus, lead Wal-Mart to stop buying farmed salmon from Chile, the world’s secon... Read More
