The 4 Borrelia burgdorferi sensu lato isolates obtained from 1. Ricinus ticks collected in the natural foci in Russia and Ukraine, having an unusual RFLP Msel-pattern, were studied using sequencing rrfA-rrlB spacer and rrs gene. The Ir-5215 isolate from the tick collected in southern Ukraine represented recently described genospecies B. spielmanii pathogenic for humans. The three atypical isolates Ir-3519, Ir-4721, and Ir-4812 had 100% identity with the sequence of the atypical European B. burgdorferi sensu stricto strains. They constituted a subgroup of the B. burgdorferi sensu stricto on the grounds of Multilocus sequence analysis (MLSA). These data can be indicative of the genetic heterogeneity of the current group B. burgdorferi sensu stricto.
从俄罗斯和乌克兰自然疫源地采集的蓖麻蜱中获得的4株伯氏疏螺旋体狭义种分离株，具有不寻常的RFLP Msel模式，使用rrfA-rrlB间隔区和rrs基因测序进行了研究。来自乌克兰南部采集蜱的Ir-5215分离株代表了最近描述的对人类致病的基因种斯氏疏螺旋体。三株非典型分离株Ir-3519、Ir-4721和Ir-4812与非典型欧洲狭义伯氏疏螺旋体菌株的序列具有100%的同一性。基于多位点序列分析（MLSA），它们构成了狭义伯氏疏螺旋体的一个亚组。这些数据可能表明当前狭义伯氏疏螺旋体组的遗传异质性。
