EVALUATION OF NEWCASTLE DISEASE VIRUS MATERNALLY DERIVED ANTIBODIES IN QUAIL CHICKS FOR ESTIMATION OF PROPER VACCINATION TIME

Evaluation of maternal antibody levels for establishing the vaccination program against Newcastle disease in ostrich chicks

  Newcastle disease virus (NDV) is known as one of the most important endemic viral pathogen for various avian species such as ostrich, in Iran. Therefore, establishing a routine vaccination program against ND in ostrich flocks would be useful in order to reduce the danger of this infection. Newcastle disease occurs among the ostriches and leads to high rate of mortality while most of the losse...

Proper Timing of Foot-and-Mouth Disease Vaccination of Piglets with Maternally Derived Antibodies Will Maximize Expected Protection Levels

We investigated to what extent maternally derived antibodies interfere with foot-and-mouth disease (FMD) vaccination in order to determine the factors that influence the correct vaccination for piglets. Groups of piglets with maternally derived antibodies were vaccinated at different time points following birth, and the antibody titers to FMD virus (FMDV) were measured using virus neutralizatio...
