The Kaliningrad Oblast, located in the westernmost part of Russia and bordering European Union countries, is a popular tourist destination. However, limited research has been conducted on the bacteria found in ticks in this region. We, therefore, investigated the prevalence of certain bacteria, including , , , and , as well as the genospecies of the spotted fever group (SFGR) in and tick species. To accomplish this, we employed commercial qPCR for pathogen screening. We identified specific genospecies by sequencing the and gene fragments. In ticks, we found sensu lato DNA in 35.6% of samples. We also found in 17.5% of ticks. Additionally, we detected in 1.7% and in 2.6%, while / were present in 0.6%. In ticks, we detected only subsp. DNA, with a prevalence of 6.1%. These findings demonstrate a substantial risk of Lyme disease and other tick-borne infections from early spring through late autumn, emphasizing the importance of ongoing monitoring for these pathogens in the region.
加里宁格勒州位于俄罗斯最西部，与欧盟国家接壤，是一个受欢迎的旅游目的地。然而，对该地区蜱虫中发现的细菌的研究有限。因此，我们调查了某些细菌的流行情况，包括 、 、 、 ，以及 蜱和 蜱物种中斑点热群立克次氏体（SFGR）的基因种。为了实现这一目标，我们采用商业定量聚合酶链反应（qPCR）进行病原体筛查。我们通过对 和 基因片段进行测序来鉴定特定的基因种。在 蜱中，我们在35.6%的样本中发现了广义的 DNA。我们还在17.5%的蜱中发现了 。此外，我们在1.7%的蜱中检测到 ，在2.6%的蜱中检测到 ，而 / 在0.6%的蜱中存在。在 蜱中，我们仅检测到 亚种的DNA，流行率为6.1%。这些发现表明，从早春到晚秋，莱姆病和其他蜱传感染存在重大风险，强调了对该地区这些病原体进行持续监测的重要性。
