Abstract Background Many viral pathogens are poorly characterized are difficult to culture or reagents are lacking for confirmatory diagnoses. We have developed and tested a robust assay for detecting and characterizing large DNA viruses and adenoviruses. The assay is based on the use of degenerate PCR to target a gene common to these viruses the DNA polymerase and sequencing the products. Results We evaluated our method by applying it to fowl adenovirus isolates catfish herpesvirus isolates and largemouth bass ranavirus iridovirus from cell culture and lymphocystis disease virus iridovirus and avian poxvirus from tissue. All viruses with the exception of avian poxvirus produced the expected product. After optimization of extraction .
