One of the basic requirements of evolution is variation in a population upon which selection can act. One of the sources of variation is mutation in DNA. These changes may or may not be reflected in the ensuing amino acid sequence of a protein. This exercise explores the additive effects of m... Read More
A permissive vaccine prevents disease in the immunized host, but does not block virus infection. Would a permissive vaccine lead to the emergence of more virulent viruses?
This hypothesis is based on the notion that viruses which kill their hosts too quickly are not efficiently transmitted, a... 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
Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.
The study ... Read More
Dear Vincent, Dickson and Daniel,
I like your idea of a TWIP coffee mug prize (or maybe a mug discount).
In this second case study you presented, the present symptoms are pretty vague, but his history is interesting. Also since with ... Read More

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
