When infection with hepatitis C virus goes from acute to chronic, severe liver disease may occur which requires organ transplantation. Nearly 200 million people are chronically infected with HCV, necessitating approaches to preventing and treating infections. No HCV vaccine is available, and cur... Read More
A dairy cow in California is the fourth known American case of mad cow disease, which is caused by prions, infectious agents composed only of protein (the story hit the press the day after my lecture on this type of illness). Unlike viruses, prions have no nucleic acid and no protective coat. Bu... Read More
Hello People of TWIV!
Thanks for all the information you give and how you make me think. I really liked your discussions on TWIV 136 - exit XMRV, not as much for the science ( which was cool) but for the discussio... Read More
What is a vaccine, and why do we need them? How do vaccines work, and how were they developed? In this lesson, students gauge their previous knowledge about vaccines. They then explore the history and biology of vaccines and create educational posters on the nature of vaccines and public opinion... Read More

There is an excellent question in the comments to “Are all virus particles infectious?“: if the particle-to-PFU ratio for a virus stock is 10,000:1, and I infect 1,000,000 cells with 10,000 particles, how many plaques would I expect to observe? Answering this question provides insight into the p... Read More
