title: Detection of fowl adenovirus DNA from formalin-fixed and paraffin-embedded sections by PCR and classification of serotypes by sequencing of PCR products.
abstract: Detection of fowl adenovirus (FAV) DNA from formalin-fixed and paraffin-embedded (FFPE) sections was attempted by PCR. Serotypes of FAV were classified by sequencing the PCR products. In trials of PCR using a positive control infected with serotype 2 FAV, the best primer set was 57F forward primer (5'-CAARTTCAGRCAGACGGT-3') and 26R reverse primer (5'-GGCTTGACGTACGCTCCGTA-3'). A second PCR with the same primer set revealed a clearer band in the electrophoresis of generated PCR products. Generated PCR products were confirmed to be derived from infected FAV. In addition, PCR and sequencing of PCR products of the liver FFPE sections, from two natural inclusion body hepatitis cases that were not examined for virologic isolation, suggested that the detected FAV was serotype 8a. The PCR of FFPE sections, and serotyping by the sequencing of PCR products, are useful for diagnosis and epidemiologic analysis of FAV infections.
