Interpretive Summary:

Technical Abstract: PCR was used in diagnosis of Marek’s disease (MD) and reticuloendotheliosis (RE) in formalin-fixed, paraffin-embedded (FFPE) tumorous tissues that have been stored for periods varied from 5-244 months. In another experiment, PCR was also used in diagnosis of MD in tumorous tissues that have been only preserved in formalin for periods that varied from 7-49 days. MD and RE were detected in FFPE tissues tested even in those stored for up to 20+ years; MD was also detected in tissues preserved in formalin for up to 7 weeks. Results indicated that PCR is a useful tool that can be used in diagnosis of MD and RE in affected tissue stored as FFPE tissue blocks or in those only preserved in formalin. The advantages of using PCR in confirming diagnosis of MD in formalin preserved tissues will be discussed.
