Influenza A virus reservoirs in animals have provided novel genetic elements leading to the emergence of global pandemics in humans. Most influenza A viruses circulate in waterfowl, but those that infect mammalian hosts are thought to pose the greatest risk for zoonotic spread to humans and the ... Read More
The novel human retrovirus XMRV has been associated with prostate cancer and chronic fatigue syndrome. The nucleotide sequence of XMRV isolated from humans indicates that the virus is nearly identical with XMRV produced from a human prostate tumor cell line called 22Rv1. This cell line was deriv...

How cool is that to be listening to you all reading my emails with Peter Sandman while I am stuck in traffic.
I loved the discussion and want to send a big thank you to Michael for joining in and giving us the missing perspective of what the NSABB ... Read More

Yesterday I sent my Skype audio question again, and I think it worked this time. In my question I mentioned a particular youtube video. Here's the link if you want to see what I was referring to. It's only 5 minute... Read More
This teleconference is sponsored by the American Society for Microbiology and will review the history and importance of methicillin-resistant Staphylococcus aureus (MRSA) with a primary focus on the emergence of community-associated MRSA (CA-MRSA). The phenotypic and molecular identification of ... Read More
Robert H. Silverman, one of the authors on the study implicating the new human retrovirus XMRV as an etiologic agent of chronic fatigue syndrome, has written an excellent review article on the current status of research on the virus. The article is behind a paywall at Nature Reviews Urology, so ... Read More
Jeff Fox of Microbe magazine interviews Kim Lewis of Northeastern University--
Missing siderophores may account for why microbiologists can culture only about 1% of the microorganisms that they collect from diverse environments, according to Kim Lewis of Northeastern University and his collabor... Read More
Dear Twiv Folks
I teach an intro biology course on viruses at Vassar College. We do our introductory biology a little bit differently; each class has a theme through which we explore the fundamental principles of biology. Mine is on viruses and t... Read More
Some viruses that infect bacteria (bacteriophages) deliver their DNA into the host cell with an amazing injection machine. The tailed bacteriophages (such as T4, illustrated) store their DNA in a capsid attached to a long tail tube that is surrounded by a sheath. At the bottom of the tube is a b... Read More
Science writer Carl Zimmer writes a masterful blog piece tracing the history of the study of ecosystems, from lakes to the human microbiome. Just one interesting fact: In their lifetimes, individual humans will produce about five elephants worth of microbes. Read More
How about using compost that includes road kill? I heard a billion pounds of animal byproducts go to landfills rather than into animal feed to prevent spread of mad cow disease. Compost that, too?
A second virophage has been identified. The name does not signify a virus that infects another virus – it means virus eater.
When my laboratory discovered the cell receptor for poliovirus in 1989, many new research directions were suddenly revealed – such as creating a mouse model for poliomyelitis. One application we did not think of was to use the receptor to screen samples of drinking water for the presence of viru... Read More
Dear TWiM Team
I see that some action is now being taken in America against the non-therapeutic use of antibiotics as livestock growth promoters:
