Isolation of four serotypes of epizootic hemorrhagic disease virus from <i>Culicoides</i> spp. and their associated infections in cattle in Yunnan, China.

ABSTRACT: Epizootic hemorrhagic disease (EHD) is a noncontagious viral infection transmitted by certain species of the genus Culicoides and has been included on the World Organization for Animal Health (OIE) list of diseases affecting domestic and wild ruminants. This study isolated four serotypes of EHDV strains (EHDV-1, -5, -6, and -7) from three Culicoides species collected in Yunnan Province, China. The phylogenetic analysis of Seg-3 revealed that EHDVs can be classified into two groups based on their geographical origins: Eastern and Western. The four isolates examined in this study belong to the Eastern group and are genetically most similar to EHDVs found in Japan and Australia. In the Seg-2 and Seg-6 phylogenetic trees, all EHDV serotypes can be classified into four clusters (G
