Rapid genomic evolution of a non-virulent coxsackievirus B3 in selenium-deficient mice results in selection of identical virulent isolates.
TL;DR: To the best of the knowledge, this is the first report of a specific nutritional deficiency driving changes in a viral genome, permitting an avirulent virus to acquire virulence due to genetic mutation.

TL;DR: The general population of CVB3/20 virions, as a consequence of replicating in an Se-deficient host, underwent a phenotypic change to increased virulence, which has important implications for the emergence of virulent viruses.
Journal ArticleDOI
Dietary selenium levels needed to maintain balance in North American adults consuming self-selected diets.
TL;DR: The levels of dietary selenium reported here as necessary to maintain balance in North American adults are considerably higher than those previously reported as needed for balance in adult women from New Zealand, a country where low selenum status is common.
