摘要
In October 2012, a 3-year-old bullfinch (Pyrrhula pyrrhula) held in captivity for its entire lifespan and a wild adult great spotted woodpecker (Dendrocopos major), both with neurological signs, were found 4 km from each other and 5 days apart in the Meuse Valley, Belgium. Non-suppurative encephalitis and mild degeneration and necrosis were identified in the brain and cerebellum, and Usutu virus antigen and RNA were detected by immunohistochemistry and real-time reverse transcriptase PCR, respectively. The two cases reported here represent the most western distribution of clinical disease in birds due to Usutu virus in Europe.
