摘要:

目的 了解辽宁省丹东市鸭绿江沿岸虫媒病毒的种类和分布情况。方法 使用诱蚊灯捕蚊,通过组织培养法分离病毒,并对病毒分离物进行血清学和分子生物学鉴定。结果 2007年7月在辽宁省丹东市鸭绿江沿岸6个采集点采集到3属3种共3359只蚊虫标本,从中分离到11株病毒分离物,鉴定结果显示有5株为版纳病毒,3株为环状病毒样病毒,其余3株分离物有待进一步鉴定;版纳病毒新分离株序列分析结果显示,5株版纳病毒之间第12片段序列高度同源,核苷酸同源性为92.1%~99.8%;氨基酸同源性为92.8%~99.5%;并且与北京分离株和云南分离株同源性较高,核苷酸同源性为91.3%~98.7%;氨基酸同源性为90.8%~100%;系统进化分析提示,版纳病毒新分离株与北京、云南分离株位于同一个进化分支中。结论 在辽宁省丹东市鸭绿江沿岸首次分离到版纳病毒和环状病毒样病毒,新分离版纳病毒与北京、云南分离株进化关系较近。

Abstract:

Objective To investigate the types and distribution profiles of arboviruses at the riverside of Yalu River in Dandong, Liaoning province, China. Methods Mosquito samples were collected with mosquito lamps and then used for virus isolation by tissue culture. The obtained virus isolates were identified by serological and molecular biological methods. Results A total of 3359 mosquitoes (3 species, 3 genera) were collected from 6 sites at the riverside of Yalu River in July 2007. Eleven virus strains were isolated from the mosquito samples. Of the 11 strains, 5 were identified as Banna Virus (BAV), 3 were identified as Orbivirus, and 3 needed further identification. Based on the results of sequence analysis, the 5 BAV strains shared high homology in terms of the 12th segment, with nucleotide and amino acid homologies of 92.1%-99.8% and 92.8%-99.5%, respectively, and were highly homologous with those from Beijing and Yunnan province, China, exhibiting nucleotide and amino acid homologies of 91.3%-98.7% and 90.8%-100%, respectively. Phylogenetic analysis showed that the 5 BAV strains and the BAV strains isolated from Beijing and Yunnan province were located in the same branch. Conclusion BAV and Orbivirus were first isolated at the riverside of Yalu River in Dandong, Liaoning province, China, and the newly isolated 5 BAV strains have a close phylogenetic association with BAV strains isolated from Beijing and Yunnan province, China.
