Adapted Tembusu-Like Virus in Chickens and Geese in China

Abstract

An outbreak of egg drop disease occurred in many chicken and goose farms in China in 2011. By using an NS5-specific reverse transcriptase PCR (RT-PCR), we found that 56% of chicken and 38% of goose samples were positive for Tembusu-like virus (TMUV). Isolates showed high sequence homology to duck TMUVs, and chickens and geese showed signs of egg drop disease after experimental infection with duck TMUV. Our data suggest TMUV has adapted in domestic birds.
