Monitoring Anti-NS1 Antibodies in West Nile Virus-Infected and Vaccinated Horses

Figure 2

Comparison of serological results, expressed as VLP/NS1 OD ratios (net OD in VLP ELISA divided by net OD in NS1 ELISA) obtained with different series of sera from five horses experimentally inoculated with inactivated WNV vaccine (dashed lines) and two experimentally infected horses (continuous lines), as described in the Materials and Methods section. The horizontal line set at a ratio (R)=4 depicts the cut-off value selected in this study for differentiation of vaccinated and infected horses.
