Comparison of FMD Type O-Asia I antibody groups qualified rate in cattle after different immunization
Abstract：In this study, large amount breading field of cattle were chosen to investigate the deamplification rule of type O and type O-Asia I. Liquid phase block ELISA was used to determine the type O-Asia maternal antibody in Cattle and to calculate the group qualified rate.The group qualified rate at day 28 after first, second and third immunization with FMD type O and type O-Asia I combined vaccine are 82.5%, 97.5% and 97.5%.The group qualified rate droped sharply after the first immunization. The type O antibody group qualified rate droped to 72.5% after first immunization at day 60. The type O and type O-Asia I droped to 47.5% and 12.5% after first immunization at day 80. Cattle which injceted the vaccine twice presented a higher group qualified rate than the group which just injected once during day 28 to 120, and the antibody lasted longer. After the third immunization the type O and type O-Asia I group qualified rate remain 77.5% and 75% on day 120.
