Genetic analysis reveals geographic groupings of Palyam serogroup viruses in cattle from Culicoides spp., indicating circulating strains in Yunnan, China.
Key Points
Three Palyam serogroup virus strains were isolated from Culicoides spp., showing unique genetic characteristics.
Seroprevalence for various viral strains in local cattle was recorded at 3.4%, 6.9%, and 16.9% for different serotypes.
Next-generation sequencing was utilized for obtaining complete genomes, with significant phylogenetic implications noted.
These findings highlight the biological diversity of PALVs, calling for further research in the region regarding their impact on livestock.
