Caliciviruses are not very well studied because until 2010, they could not be grown in culture, and they have a very narrow host range and no suitable animal model. However, the application of modern genomic technologies has led to an increased understanding of the virus family. A 2013 isolate from rhesus monkeys — Tulane virus —can be grown in culture, and this system promises to increase understanding of these viruses.
