Great HAI work! I'm not through it yet. I want to question, though, whether fomites are really important in influenza transmission. I don't think so.

The UK's National Center for Biology Eduction has an interesting experiment involving toilet paper, hot water and oyster mushroom starter culture.
"Gastronomes will no doubt be aware of the presence of an increasing range of exotic mushrooms on the supermarket shelves. In the Far East, oyster... Read More
Your discussion about technology and fixing things here before we go out into space made me wonder if space exploration might turn out to be like investigative science. In the process of exploring space we might run across the means of fixing our probl... Read More
Hi Drs. Despommier and Racaniello,
This week you wondered why the immune-activating receptor for Toxoplasma gondii, TLR11, is present in mice but not in humans. You noted that it looks like there's no selective pressure keeping it around in us an... Read More
Every different life form on earth can probably be infected with at least one type of virus, if not many more. Most of these viruses have not yet been discovered: just over 2,000 viral species are recognized. While the majority of the known viruses infect bacteria and eukaryotes, there are only ... Read More
Michael returns to help the TWiP trio solve the case of the Delusional African Expatriate, who then discuss the association of natural and induced antibodies in mice with differential susceptibility to secondary cystic echinococcosis.

Dotplots are an extremely useful way of visualizing comparisons of small and large DNA sequences (as well as protein sequences), providing insight into the degree of similarity, deletions, insertions and direct and indirect repeats. In a dotplot, each nucleotide, or small window of nucleotides, ... Read More
The TWiM team explores microbes in snowblower vents on the ocean floor, and cleavage of antibody molecules by a Mycoplasma protease.

On episode #75 of the podcast This Week in Virology, Vincent, Alan, and Matt review contamination of Rotarix with circovirus DNA, antigenic similarity between 1918 and 2009 H1N1 influenza, a ... Read More
Here's a movie from the University of Madison-Wisconsin depicting the steps for creating an acid fast stain.
A eukaryote without a mitochondrion, and using a phage enzyme to eliminate intracellular bacteria are two topics discussed by the TWiMers on this episode.

Have you heard about the Earth Microbiome Project? Led by the laboratories of Jack Gilbert from Argonne National Labs along with Folker Meyer (Argonne), Janet Jansson (LBNL), Rob Knight (University of Colorado), this is a pioneering effort to characterize the global microbial taxonomic and func...
