Abstract:
Classical swine fever virus (CSFV) causes severe economic losses to the swine
industry worldwide. To gain insight into the molecular epidemiology of classical
swine fever in China, we analyzed a 190 bp N-terminal fragment of the E2 gene
of 103 Chinese CSFV isolates. Clinical samples were collected between January
2008 and March 2011. CSFV was detected in 103 of these samples by RT-nested
PCR and were selected for sequencing. Further analysis based on the E2 fragment
sequences revealed that all of the Chinese isolates belonged to subgroups 1.1,
2.1 and 2.2. CSFV isolate of genogroup 3 was not found. The most significant
observation between genetic and geographical distribution for the isolates in
the study, especially for the subgroup 2.1 strains, was that they occupied the
widest area since these viruses existed throughout mainland China. These results
enhance our knowledge of the phylogenetic diversity of Chinese CSFV isolates
and may contribute to the development of reliable diagnostic tests, epidemiological
surveillance and effective strategies for disease control.
