FIG. 8.
GL protein-specific antibody responses of ponies 7b69, 07d41, 5062, and 697b after intranasopharyngeal immunization (ponies 7b69 and 07d41) with EAV-GLΔ (day 0) and intranasopharyngeal challenge infection with EAV LP3A+ (day 46; arrows) measured by ELISA for antigens GL-6His (GL residues 18 to 122) and GL-OVA (GL residues 81 to 106). Reactivities of sera are expressed with respect to that for a positive-control serum sample obtained from pony p6 2 weeks after vaccination with GL-6His antigen (14).
