Hello fellow virus lovers,
I first want to comment about Vincent's pick of the week a few weeks back, the book "Polio" by David Oshinsky. I am currently studying poliovirus in Julie Pfeiffer's lab (as you revealed many moons ago with a previous ... Read More
Does the same concern that you discussed with suppressed immunity after a transplant apply to folks who undergo chemotherapy for cancer? (re strongyloides)

The World Health Organization has decided not to recommend destruction of the remaining stocks of smallpox virus. This debate has been ongoing since 1980, when the disease was declared eradicated. WHO has indicated that no new experiments on smallpox virus will be permitted, only conclusion of o... Read More
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
If you know anything about snakes you might be familiar with snake inclusion body disease, or IBD. This transmissible and fatal disease affects snakes of a variety of species but has been best studied in boas. The name comes from the presence of large masses (inclusions) in the cytoplasm of cell... 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
Glenn Rall, a virologist at Fox Chase Cancer Center, sent me the following note:
Baruch S. Blumberg, Nobel Laureate in 1976 for discovery of Hepatitis B (and the eventual development of the vaccine, which probably has saved hundreds of thousands of lives since its introduction), died this pas... Read More

Hi Dr Racaniello,
I am a long time listener of TWIV and really enjoy the informal scientific discussions. I listen to TWIV while working in the lab and am trying to catch up on TWIM and TWIP episodes too.
I have been dill... Read More
Hello People of TWIV!
Thanks for all the information you give and how you make me think. I really liked your discussions on TWIV 136 - exit XMRV, not as much for the science ( which was cool) but for the discussio... Read More
A year has passed since the last reported case of poliomyelitis in India, which occurred on 13 January 2011 in a two year old girl in Howrah, West Bengal. Read More
One of two papers on avian influenza H5N1 virus that caused such a furor in the past six months was published today in the journal Nature. I have read it, and I can assure you that the results do not enable the construction of a deadly biological weapon. Instead, they illuminate important requir... Read More
After 86 episodes of TWiV, I am still loving every minute of the podcast and I am constantly impressed with how much I learn. For example, I have been mentoring an undergraduate student in the lab and we have had a rough two week stret... 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
