Abstract:
OBJECTIVETo identify the virus isolated from a mosquito Culex modestus collected from Tongliao city of Inner Mongolia Autonomous Region.
METHODSA strain of virus isolated from mosquito in Tongliao city was identified by serological and molecular biological methods. The nucleotides of the virus isolate were amplified by RT-PCR, and the products were purified and sequenced. Multiple alignment, phylogenetic and amino acid (AA) analysis were carried out by software Clustal X, MEGA4 and MegAlign (DNAStar).
RESULTSThe new isolate was identified to be Banna virus by serological and molecular biological methods. Phylogenetic analysis showed that the Chinese isolates were distributed within one cluster. The homologue of nucleotide and amino acid of 12 segments between the new isolate and other strains isolated from China were 89.6%-98.4% and 90.4%-98.6%.
CONCLUSIONThe virus isolated from Culex modestus in Inner Mongolia belonged to Banna virus, and it is the first time that Banna virus was isolated in this region.
