AbstractA difficulty in studying hemorrhagic arenavirus pathogenesis is a lack of animal models that recapitulate human disease and which can be manipulated at BSL-3 or lower. Pirital virus (PIRV), a South American arenavirus hosted by Alstons cotton rats (Sigmodon alstoni), has not been shown to cause disease in humans and is considered a BSL-3 agent. Infection of Syrian golden hamsters (Mesocricetus auratus) causes a disease that shares many features of the South American hemorrhagic fevers and Lassa fever. Significantly, neurological manifestations occur, a feature commonly found in Argentine hemorrhagic fever and which is absent in most other models of arenavirus disease. We examined the pathogenesis of PIRV infection by clinical and molecular methods, with a focus on gene expression of the antiviral type I interferon response using RNA-Seq.
