Abstract

After a 15-year long disease free period, the authors report the re-occurrence of duck viral hepatitis in 2004 and 2005. The epidemic occurred in the South of Hungary between the river Duna and Tisza, and affected 112 Peking and one Mulard duck flocks. In typical cases mortalities began at the age of 8 to 9 days and continued until day 16 to 17. Losses due to mortality ranged from 25 to 30%. The observed clinical symptoms, pathological and histopathological changes were similar to those described earlier in the literature. The virus was isolated in embryonated Muscovy duck eggs and identified by virus neutralisation as type 1 duck hepatitis virus. Individual efforts to control the disease and reduce losses, by vaccination of day old ducklings or by introduction of geese groups between duck shifts were only partially successful. Our experience confirmed that successful control of the disease can only be achieved by the simultaneous application of preventive sanitary measures and biosecurity, e. g. breaking the infection chain, preventing virus introduction and by adequate vaccination of the breeding flocks.
