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, and are therefore removed by selection. However a vaccine …
I am pleased to announce the publication by ASM Press of the fourth edition of our virology textbook, Principles of Virology. Two years in the making, this new edition is fully updated to represent the rapidly changing field of virology. Principles of Virology has been written according to the authors’ philosophy that the best approach to teaching introductory …
Foot-and-mouth disease virus (FMDV) infects cloven-hoofed animals such as cattle, pigs, sheep, goats, and many wild species. The disease caused by this virus is a substantial problem for farmers because infected animals cannot be sold. Transgenic pigs have now been produced which express a short interfering RNA (siRNA) and consequently have reduced susceptibility to infection with FMDV. …

Although we now understand that viruses are the most abundant organisms on Earth, there are gaps in our knowledge about their distribution in different environments. Results of a new study reveal the diversity and distribution of viruses in Arctic fresh waters. Fresh waters in high latitudes such as the Arctic and Antarctic have low levels …
Patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) showed clinical improvement after extended treatment with the anti-B-cell monoclonal antibody rituximab. This result suggests that in a subset of patients, ME/CFS might be an autoimmune disease. Rituximab is a monoclonal antibody against a protein on the surface of B cells known as CD20. When the antibody is given to …
Back in 2013 I built a Wall of Polio in my laboratory – a large stack of six-well cell culture plates that have been used to measure the concentration of polioviruses in various samples by plaque assay. It became a focal point of the lab at which many guests came to have their photographs taken. Sadly, the …
