巴贝斯虫病是一种蜱传播的疾病，具有兽医和医学重要性。最近记录了奥地利首例人类巴贝斯虫病。在目前的研究中，蜱在所有生命周期阶段（龄），包括853个硬蜱蓖麻和11个血蜱concinna蜱，从奥地利各地的采样点进行了检查，是否存在巴贝属。18S rRNA基因PCR和测序法检测，总平均感染率为51.04%。采样点的感染率差异很大，从0%到几乎100%不等。不同虫龄和不同性别的感染几乎相等。通过对热休克蛋白70基因片段和内部转录间隔区1和2进行测序，将奥地利蜱中发生的巴氏杆菌分离株鉴定为分歧巴氏杆菌、分歧巴氏杆菌样和巴氏杆菌属DD菌株。据我们所知，这是第一次调查Babalypspp。奥地利的蜱虫。
Babesiosis is a tick-transmitted disease of veterinary and medical importance. The first Austrian case of human babesiosis was recently recorded. In the current study, ticks at all life cycle stages (instars), including 853 Ixodes ricinus and 11 Haemaphysalis concinna ticks, from sampling sites throughout Austria were examined for the presence of Babesia spp. by using 18S rRNA gene PCR and sequencing, and the overall mean infection rate was 51.04%. The infection rates for sampling sites were highly variable, ranging from 0% to almost 100%. Different instars and different sexes were infected almost equally. Babesia isolates occurring in Austrian ticks were identified as Babesia divergens, Babesia divergens-like, and Babesia sp. strain DD by sequencing a fragment of the heat shock protein 70 gene and internal transcribed spacer regions 1 and 2. To our knowledge, this is the first investigation of Babesia spp. in Austrian ticks.
