Technical Abstract: Avian pneumovirus (APV) is the causative agent of turkey rhinotracheitis (TRT) which results in primarily a respiratory disease. Previous research in our lab indicates that inactivated APV vaccines do not induce serum virus-neutralizing antibodies and are not protective. The objective of this study was to compare cellular immune mechanisms of purified turkey lymphocytes from control and immunized birds. The effect of APV infection on the avian immune system was examined by comparing APV-specific serum and local IgG, IgM or IgA antibodies following virus challenge.
