Abstract
- During investigations into an outbreak of egg production decline, retarded growth, and even death among ducks in Southeast China, a novel Tembusu virus strain named Tembusu virus Fengxian 2010 (FX2010) was isolated. This virus replicated in embryonated chicken eggs and caused embryo death. In cross-neutralization tests, antiserum to the partial E protein of Tembusu virus Mm1775 strain neutralized FX2010, whereas antiserum to Japanese encephalitis virus did not. FX2010 is an enveloped RNA virus of approximately 45-50 nm in diameter. Sequence analysis of its E and NS5 genes showed that both genes share up to 99.6% nucleotide sequence identity with Baiyangdian virus, and up to 88% nucleotide sequence identity with their counterparts in Tembusu virus. FX2010 was transmitted without mosquito, and caused systemic infection and lesions in experimentally infected ducks. These results indicate that FX2010 and BYD virus are newly emerged Tembusu virus strains that cause an infectious disease in ducks.<br /> (Copyright © 2011 Elsevier Inc. All rights reserved.)
