Abstract: Duck virus hepatitis (DVH) was one of the most important diseases to cause economic losses in the duck industry. The test confirmed the virus of dead duck for duck virus hepatitis type Ⅰby viral isolation, duckling regression test, the DHV ELD50 determination, ducklings protection test, neutralization test in chicken embryos, innoculation test in duck embryo and electron microscopy observation and so on. There were some differences in pathological features of regression experiments of duck hepatitis virus type Ⅰ and standard virus that the determination and analysis of gene sequences needed to be further studied.

Key words: duck virus hepatitis type Ⅰ; isolation; identification
