| Abstract;A serological survey conducted in Okayama Prefecture from September to November, 2001, revealed that 35% of the farms and 27.6% of sentinel calves investigated were positive for antibodies to the Akabane virus (AKAV). The virus was isolated from erythrocytes and blood plasma of a sentinel calf in late September. As a result of the cross-neutralization (NT) test, the isolates demonstrated various antigenic relationships to the reference (JaGAr39) strain and a distinct antigenic relationship with a highly virulent AKAV known as the Iriki strain. S RNA sequence data identified the isolate as the same as reported AKAVs. Phylogenetic analysis with known AKAVs put the isolate in the cluster that includes the Iriki strain, but in a very divergent position. These results suggest that the isolate may be a new genotype.
