Evolution of Tembusu Virus in Ducks, Chickens, Geese, Sparrows, and Mosquitoes in Northern China.

ABSTRACT: Tembusu virus (TMUV) is a contagious pathogen from fowl that mainly infects ducks and geese, causing symptoms of high fever, loss of appetite, retarded growth, neurological symptoms, severe duck-drop syndrome, and even death. During an epidemiological investigation of TMUV in Northern China, we isolated 11 TMUV strains from ducks, chickens, geese, sparrows, and mosquitoes (2011⁻2017). Phylogenetic analysis of the open-reading frames of genes revealed that these strains clustered into Chinese strains II. The nucleotide and amino acid homologies of NS1 of the strains ranged between 85.8⁻99.8% and 92.5⁻99.68%, respectively, which were lower than those of E (86.7⁻99.9% and 96.5⁻99.9%, respectively), NS3 (87.6⁻99.9% and 98.2⁻99.8%, respectively), and NS5 (86.5⁻99.9%
