[Arbovirus investigation in some regions of Shanxi province in 2007].

OBJECTIVE
To investigate arboviruses in some regions of Shanxi province, isolation and identification for arbovirus activity from mosquitoes was conducted.


METHODS
Mosquitoes were collected from these area in 2007 and then used for virus isolation by cell culture. The virus isolates were identified by molecular biology and the sequences were analyzed by bioinformatics.


RESULTS
Ten Banna virus (strains SX0765, SX0766, SX0767, SX0771, SX0789, SX0790, SX0793, SX0794, SX0795, SX0796) were isolated, and two Liaoning virus were also isolated from isolates SX0771, SX0794. Phylogenetic tree of the Banna virus isolates showed that ten strains are located in a distinct branch from all of the other Chinese Banna virus isolates. The homology is between 89.7% and 94.1%.


CONCLUSION
Ten Banna virus and two Liaoning virus were isolated during this arbovirus investigation in Shanxi province. New Banna virus isolates showed a distinct phylogenetic relationship with the other Chinese Banna virus strains.
