摘要
目的了解辽宁地区炭疽芽胞杆菌的流行特征及菌型基因特征。方法通过多位点可变数目串联重复序列(Multiple locus variable numbers of tandem repeats analysis,MLVA)分型实验,对2001—2011年辽宁省分离到的6株炭疽芽胞杆菌分离株DNA进行检测,DNA指纹图谱使用BioNumerics 4.0软件进行统计分析,得出聚类分析结果。结果聚类分析发现,6株炭疽芽胞杆菌株可分为2个基因型。对于炭疽暴发而言,其可变数目串联重复序列遗传标记具有高度相似性。结论炭疽芽胞杆菌基因组中的串联重复序列可作为炭疽芽胞杆菌基因分型的指标,在炭疽暴发事件中的病原体溯源上具有重要的意义。
The epidemic characteristics and genotype of Bacillus anthracis strains in Liaoning Province ,China was analyze in this study .Six Bacillus anthracis strains from 2001 to 2011 were studied with multiple‐locus variable‐number tandem repeat analysis （MLVA） .BioNumerics4 .0 software was used to analyze the DNA fingerprint of statistics ,and cluster analysis results were obtained .Clustering analysis found that the 6 strains could be divided into two genotypes .For anthrax outbreaks ,the ge‐netic markers of multiple‐locus variable‐number tandem repeat were highly similar .It＇s suggested that MLVA is quite useful for investigation of strain relatedness in regions of outbreaks .
