Figure 1. Viremia profiles for West Nile virus (WNV)–infected American Crows after injection of 1,500 PFU of KUN or KEN/NY99 WNV. Viral titers were determined by plaque formation on Vero cells and represented as geometric means. A detection limit of >1.7 log10 PFU/mL crow serum was determined. Bars represent standard deviations (SD) of the mean. hd, high dose.
