Abstract

Candidatus Borrelia kalaharica was proposed as bacterial species in 2016 using DNA extracted from a traveller returning from Southern Africa. We investigated DNA of three soft ticks collected in the Kalahari Game Reserve near Maun, Botswana via PCR. One of the DNA extracts yielded positive results for four Borrelia multilocus sequence typing (MLST) genes with allele sequences closely or exactly matching alleles of Ca. B. kalaharica. Sequencing of PCR products targeting the Ornithodoros 16S rRNA gene revealed closest matches (99 - 100% coverages, >99.7 % identity) to Ornithodoros kalahariensis. Thus, we suggest that Ornithodoros kalahariensis is a potential vector for this Borrelia species.

卡拉哈里疏螺旋体候选者卡拉哈里疏螺旋体的潜在传播媒介。

2016年，卡拉哈里候选伯氏疏螺旋体被认为是一种细菌，研究人员从一名从非洲南部返回的旅行者身上提取了DNA。我们对在博茨瓦纳马恩附近的喀拉哈里野生动物保护区收集的三只软蜱进行了DNA PCR研究。其中一份DNA提取液的4个伯氏疏螺旋体多位点序列分型（MLST）基因的等位基因序列与卡拉哈里卡伯氏疏螺旋体等位基因接近或完全匹配。针对Ornithodoros 16S rRNA基因的PCR产物测序结果显示，与卡拉哈里鸟（Ornithodoros kalahariensis）的匹配度最高（覆盖率为99 ~ 100%，同源性为99.7%）。因此，我们认为卡拉哈里鸟是该伯氏疏螺旋体的潜在媒介。

期刊介绍： Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
