ABSTRACT
The E2 genes of 73 classical swine fever virus (CSFV) originated from CSF suspected cases in different regions of China were genetically characterized and compared with reference CSF viruses. All Chinese viruses that characterized were segregated into two major groups and subdivided into four subgroups. Most of isolates (61.6%) belonged to group 2 and were further divided into three subgroups subgroup 2.1, 2.2 and 2.3. Subgroup 2.1 was the largest subgroup which contained 46.6% of isolates, while subgroup 2.3 was the smallest subgroup which contained only one isolate (1.4%). The remaining 38.4% of isolates were classified into subgroup 1.1 within group 1. However, no group 3 and subgroups 1.2 and 1.3 viruses were found in this study. This study has provided epidemiological information useful for assessing the virus origin and establishing a national prevention and control strategy against the disease.
