FIG. 8.

ELISA detection of anti-RPV-H, anti-HA, and anti-GFP antibodies in sera from cattle vaccinated with recombinant RPV vaccines. ELISA results are shown for the four cattle (TV58, TV59, TV60, and TV61) vaccinated with RPVINS-HA (A to D), the four cattle (TY28, TY29, TY30, and TY31) vaccinated with RPVANC-GFP (E to H), and the four cattle (TR2, TR3, TR4, and TR5) vaccinated with RPVII (I to L). The cattle were vaccinated on day 0 and then challenged with RPV Saudi 1/81 on day 28 (indicated by an arrow). Anti-RPV-H (black bars) antibody responses represent percent inhibition (left-hand y axis); anti-HA (white bars) or anti-GFP (grey bars) antibody responses represent optical densities measured at 492 nm (OD 492; right-hand y axis). The results shown in panels I to L, with the exception of the anti-HA results, are taken from reference 30.
