This species is the natural reservoir of Junin virus, the etiological agent of Argentine Hemorrhagic fever. We found different levels of variability and varying signatures of natural selection in populations with different epidemiological histories. %U https://www.biorxiv.org/content/biorxiv/early/2017/03/04/113688.full.pdf
