Resumo: Chikungunya virus (CHIKV) is an arthropod-borne virus, which is known to cause severe disease only in humans. To investigate its potential zoonotic host range - evaluate reservoir competence among these hosts, experimental infections were performed on individuals from nine avian - 12 mammalian species representing both domestic - wild animals common to North America. Hamsters - inbred mice have previously been shown to develop viremia after inoculation with CHIKV - were used as positive controls for infection. Aside from big brown bats (Eptesicus fuscus), none of the mammals or birds developed detectable viremia or overt clinical disease. However, most mammals - a smaller proportion of birds developed neutralizing antibody responses to CHIKV. On the basis of these results, it seems unlikely that CHIKV poses a significant health threat to most domestic animals or wildlife - that the species examined do not likely contribute to natural transmission cycles. Additional studies should further evaluate bats - wild rodents as potential reservoir hosts for CHIKV transmission during human epidemics.
