title: Serological surveillance for antibodies against different avian infectious agents on turkey flocks naturally infected with turkey rhinotracheitis.
abstract: Turkey Rhinotracheitis (TRT) in the state of Baden-Württemberg, Germany appears to have become endemic affecting all farms and every new restocking. In 5 meat turkey flocks, serological surveillance for antibodies to TRT-, IB- and IBD-viruses, as well as to Pasteurella multocida were carried out using ELISA tests. Furthermore, sera were examined for the presence of antibodies to avian adenovirus (CELO virus), reo- and paramyxo-viruses 1 and 3. The birds were bled at 4 week intervals starting at the first day of age through the 20th week. Serological data indicated that in all turkey flocks surveyed after natural exposure to infection, there was a significant increase to TRT antibody levels which was usually accompanied with an increase in the number of positive sera to adenovirus. In addition, no antibodies to IB- and IBD-viruses as well as to Pasteurella multocida could be detected in any of the examined sera. The results related to reo- and paramyxo-viruses 1 and 3 will also be discussed.
