Jeff Fox of Microbe magazine interviews Michael Brennan of Aeras Global TB Vaccine Foundation on efforts to develop a tuberculosis vaccine. Aeras is focusing a substantial portion of its vaccine development strategy and efforts on the venerable but flawed Bacille Calmette-Guerin (BCG) vaccine Read More
Vincent and Dickson discuss how infection of mice with helminths induces cytokines that reactivate a latent gamma-herpesvirus.
Although many archaea have tough outer cell walls, these walls contain different kinds of amino acids and sugars than those found in bacteria. Archaeal cell membranes also are chemically distinct from bacterial membranes with differing lipid structures and chemical links. This means that drug... Read More
I’m a bit behind in my Twiv listening, but I’d like to comment on something you said in Twiv 47. You have reminded us several times in the past that “viruses are not alive” and you embellished on this during Twiv 47 by saying that if they are not alive, they can’... Read More

The Welcome Trust has funded an interactive Flash game that can be played on the web that teaches young people how the flu is spread. You start off as a flu virus and the goal is to infect others. Along the way, you get educational information about viruses. Here are some of the instructions: Y... Read More
A slide-cast by Jonathan Eisen, Professor at UC Davis and Academic Editor in Chief of PLoS Biology, about open access publishing given at the Clinical and Translational Science Center at UC Davis (http://www.ucdmc.ucdavis.edu/ctsc). Read More
Since the first observations that the human retrovirus XMRV is associated with prostate cancer and chronic fatigue syndrome (CFS), new studies have been carried out to determine the role of the virus in these diseases. The results have been conflicting: XMRV (and related retroviruses) have been ... Read More

Virginia Campbell,MD, host of the Brain Science Podcast, has published a very interesting interview with Dr. Paul Offit, author of the book Autism’s False Prophets. In the interview, Campbell and Offit explore "the scientific evidence that vaccines DO NOT cause autism, but also examine why the c... Read More
After searching through hundreds of potential chemicals, German immunologist Paul Ehrlich discovers a compound that can selectively kill the parasitic spirochete that causes syphilis. The following year, he sends 65,000 free samples of the drug, now known as the first modern chemotherapy agent, ... Read More

"Rattling around inside my head for some time has been the reported discovery that there are bacteria that live within other bacteria. To me, this is an honest-to-goodness gee-whiz piece of microbial lore. Made me wonder why the story had... Read More
When you purchase chicken eggs at the market, they usually have white or brown shells. But some breeds of chicken produce blue or green eggs. The blue color is caused by insertion of a retrovirus into the chicken genome, which activates a gene involved in the production of blue eggs. Read More
Researchers from the European Institute of Oncology in Milan, Italy, analyzed three strains of the common probiotic Lactobacillus for their immunological properties and efficacy to treat or prevent inflammatory bowel disease in mice. The results suggests that each probiotic strain should be char... Read More
In this post from my microbiology/education blog, I discuss a post on Boing Boing recently that used a video I had made of ice nucleation bacteria. Ice nucleation bacteria are very interesting of course, and I link to the Boing Boing post. In addition, I provide an additional video of students... Read More
Recently, Yale’s Richard Flavell led a team of researchers into the most talked about and yet one of the least understood of microbial environments—the human gut. Rather than present the usual metagenomic characterization of the microbial population, he teamed up with Jeff Gordon at Washington U... Read More
Researchers examined samples from the brains of patients with and without dementia and found lipopolysaccharide, a component of Porphyromonas gingivalis, an oral bacterium, in four out of 10 Alzheimer’s disease brain samples.
“This clearly shows that there is an association between oral bacte... Read More
