Last Fall, the great Dr. Margaret McFall-Ngai "virtually visited" my freshman writing class at the University of Puget Sound to discuss symbiosis and Microbial Supremacy with my new students. I had my students read some papers by Dr. McFall-Ngai (including the wonderful "Animals in a Microbial ... Read More

In midsummer 1986, five years after starting my poliovirus laboratory at Columbia University, I received a letter from Frederick L. Schaffer, a virologist at the University of California, Berkeley, asking if I would like to have his collection of poliovirus stocks. He was retiring and the sample... Read More
An Ebolavirus vaccine has shown promising results in a clinical trial in Guinea. This vaccine has been in development since 2004 and was made possible by advances in basic virology of the past 40 years. Read More

Daniel: I was fascinated by your answer to the case from TWIP 91 - the life cycle of the southeast Asian worm (I won't even try to spell it.) Re early symptom coughing & wheezing: if the ED did a chest X-ray out of concern about the lungs, would the... Read More
Vincent, Dickson, and Daniel solve their fishy tale, and present a new case study for your consumption.
It goes by many names: Delhi belly. Montezuma's revenge. The Aztec two-step. But doctors use one not-so-glamorous term: traveler's diarrhea. Read More
I just went to my semi-annual dental appointment and I thought of a potentially interesting oral health monitor - the plaque biofilm that they scrape off your teeth during the cleaning. Brush immediately before the cleaning ... Read More
This article provides the preliminary results of a possible treatment/ Biological control agent for White Nose Syndrome (WNS) cause by Pseudogymnoascus destructans. It is estimated that over 5.5 of North American bats have died due to this deadly disease. Recently this method of treatment descri... Read More

The late Edward Leadbetter had a huge impact on my life as an academic, and a microbiologist. In this post, I try to give some appreciation to what he meant to me. Read More
Vincent and Rich discuss fruit fly viruses, one year without polio in Nigeria, and a permissive Mar... Read More
Each Fall, I teach a freshman writing class about symbioses and parasitism. I was very lucky to get some pretty famous people to "Skype" or "Google Hang Out" in to visit my class. Last Fall, one of my "tele-speakers" was the fabulous science writer and very funny fellow Ed Yong. The students ... 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
This is as portrait of the late Francis Crick created by my wife Dr. Jennifer Quinn using "paint" of luminous bacteria. Photobacterium leignothi was grown in LB amended to 20g/l NaCl for a few hours until visible luminescence was detected visually. The liquid culture was painted onto amended L... Read More
