Identification and Genetic Characterization of Astrovirus in Wild Boar (Sus scrofa) in China

Porcine astrovirus (PAstV) is a frequently detected virus in pigs suffering from diarrhea worldwide. Here, we report the first identification and complete genome sequence of astrovirus in wild boar (Sus scrofa) in Jiangxi, China. The complete genome sequence of a representative astrovirus, WBAstV/CH/2015, was amplified and determined. Sequence homology analysis showed that WBAstV/CH/2015 had 40.8% to 79.7% homology with PAstVs worlwide, and shared the highest homology (79.7%) with another wild boar astrovirus (WBAstV) strain WBAstV-1/2011/HUN from Hungary. Phylogenetic analysis showed that WBAstV/CH/2015 was closely related to WBAstV-1/2011/HUN and located in the cluster of PAstV 4.

Çin’de Yaban Domuzunda (Sus scrofa) Astrovirusların Tanımlanması ve Genetik Karakterizasyonu

Domuz astrovirusu (PAstV) dünya çapında ishalli domuzlarda en sıklıkla belirlenen bir virustur. Bu çalışmada, Çin’in Jiangxi eyaletinde yaban domuzunda (Sus scrofa) astrovirusun ilk tespiti ve tüm genom sekans analizi gerçekleştirilmiştir. Astrovirus WBAstV/CH/2015’un tüm genom sekansı amplifiye edildi ve belirlendi. Sekans homoloji analizi, WBAstV/CH/2015’in dünye çapında PAstVları ile %40.8 ile %79.7 arasında benzerliğe sahip olduğunu ve Macaristan’da tespit edilen diğer bir yaban domuzu astrovirus (WBAstV) suşu olan WBAstV-1/2011/HUN ile en yüksek benzerliğe (%79.7) sahip olduğunu gösterdi. Filogenetik analiz WBAstV/CH/2015’in WBAstV-1/2011/HUN ile yakın akraba olduğunu ve PAstV 4 topluluğuna yakın olarak yer aldığını göstermiştir..
