Viruses Impaired if Their Targets Have Diverse Genes

When a viral infection spread through five genetically identical mice in a row, the virus replicated faster and became more virulent or severe. But when the infection spread one-by-one through five genetically diverse mice, the virus had trouble adapting and became less virulent. The University of Utah study suggests that increased genetic diversity should be promoted in livestock and in captive-bred endangered species so as to limit their risk of getting deadly infections.
