Interpretive Summary: The ADOL and EPVD units have three active projects on poultry genomics, enteric diseases and avian herpesviruses. Selected research highlights from the last year include 1) Discovery of Ikarus gene as important driver mutation in development of Marek’s disease (MD). 2) Determination of infectious duration of Marek’s disease virus (MDV) for developing methods to reduce virus transmission. 3) Development of Newcastle disease virus (NDV) vector vaccine. 4) Confirmation of turkey herpesvirus (HVT) vector vaccine interference and evaluation of effect of mixtures on vaccine replication. 5) Development of MDV serotype 2 vaccine vector as possible strategy for avoiding HVT interference. 6) Development of infectious laryngotracheitis (ILT) infectious clone. 7) Evaluation of new sequencing methods for infectious laryngotracheitis virus. These research efforts will aid future efforts to select birds for superior disease resistance to MD, improve diagnostic methods for ILT, and improve vaccines against MD, ILT, NDV and other poultry viruses.
