Experimental infection of spotted doves with two SFTSV strains.

Abstract

Error bars represent standard error of the mean log10 PFU/mL of serum. The horizontal dashed line indicates a limit of detection of 101.8 PFU/mL. A: Spotted Doves inoculated with 107 plaque forming units (PFU) of SFTSV strain JS2014 (solid line) had higher mean viral loads that peaked earlier than did birds inoculated with 105 (dashed line) or 103 PFU (fine dashed line) of virus. B: Spotted doves inoculated with 107 plaque forming units (PFU) of SFTSV strain JS2010 (solid line) had higher mean viral loads that peaked earlier than did those birds inoculated with 105 (dashed line) or 103 PFU (fine dashed line) of virus.</p
