The Broad Understanding of the Role of Viruses in the Environment Expanded
For over 200 years viruses were studied and thought of primarily as agents of disease, something to be gotten rid of if at all possible. The Roossinck laboratory studied the occurrence and biology of viruses from environmental sources and demonstrated their impact on the ecosystems in which they reside. For example, their research demonstrated that viruses can be essential for the survival of their hosts. Roossinck pioneered the field of Mutualistic Viruses. Research from the Roossinck lab demonstrating that viruses are beneficial microbes has changed the way many scientists think about viruses.
