Greetings Vincent and Dick,
Hooray for finally mentioning G. pulchrum in episode 62, my most favorite parasite and one worthy of further discussion. As a diagnostic veterinary pathologist, I encounter this spirurid in approximately... 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

Dear Vincent, Dickson and Daniel,
I think the latest case describes cutaneous furuncular myiasis.
The lesion on the young man's buttock is suggestive of a botfly infection with the larvae most likely of the species Derm... Read More

It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Read More

In this blog entry, I discuss some recent work at the intersection of art and microbiology. I go on to show how this intersection can be useful in the classroom. Read More
Hello Dr Racaniello and Despommier,
I recently saw an article about the paper linked below on Science Daily and thought it might be worth a discussion on TWIP. It is about the possibility of bed bugs being a vector for T. cruzi. I would love to... Read More
Merry Youle of Small Things Considered fame has a new post on the site that looks at the Acidianus two-tailed virus.
"Why two tails? Why such long tails? The researchers note that ATV is the only virus of an acidophilic hyperthermophile known to lyse its host, albeit only under st... Read More
Efforts to expunge micro-organisms from spacecraft assembly cleanrooms, and the spacecraft themselves, inadvertently select for the organisms that are often the most fit to survive long journeys in space. This has the risk of thwarting the goal of avoiding contaminating other celestial bodies, a... Read More
In the Nº 101 of the "El podcast del microbio" I made a resume of the role of Wolbachiain the Plant green-island phenotype as appeared in th... Read More

Few technical breakthroughs have changed the face of their field like the Polymerase Chain Reaction (PCR). Gene cloning, sequencing of complex genomes, DNA fingerprinting and DNA-based diagnostics are just some of the techniques that were either inefficient, crude or plain impossible before PCR....

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 TWiV gang answers follow-up questions about the Ebola virus outbreak in West Africa, then discuss treatment of disseminated multiple myeloma with oncolytic measles virus.
Abstract - A crucial transition in the origin of life was the emergence of an informational polymer capable of self-replication and its compartmentalization within protocellular structures. We show that the physicochemical properties of ice, a simple medium widespread on a temperate early Earth,... Read More
