title: Antibody responses in ostriches (Struthio camelus) vaccinated with commercial live and killed Newcastle disease vaccines.
abstract: Three ostriches (Struthio camelus) were immunized with commercially available live and killed Newcastle disease (ND) vaccines for chickens and the antibody responses to the ND vaccines were evaluated by a virus-neutralization (VN) test. Primary vaccination with the live vaccine, B1, by eye drop was followed with two shots of alum-precipitated killed vaccine via subcutaneous injection in the neck. As a final booster, another live vaccine, Clone 30, was used by eye drop. A VN antibody titer, more than 1:10 was observed for 6 months. This is the first report on the use of a live vaccine by eye drop as a booster in ostriches as well as evaluating responses to ND vaccines using the VN test in this avian species.
