The Bartonella pathogen is an emerging zoonotic agent. Epidemiological studies worldwide have demonstrated that small mammals are reservoir hosts of Bartonella spp. and their ectoparasites are potential vectors. The aim of this study was to investigate the prevalence of Bartonella infections in small mammals (Rodentia, Insectivora) and their ectoparasites (fleas and ticks) in Lithuania. A total of 430 small mammals representing nine species were captured with live-traps in Lithuania during 2013-2014. A total of 151 fleas representing eight species were collected from 109 (25.8%) small mammals. Five hundred and seventy ticks (Ixodes ricinus) were collected from 68 (16.1%) small mammals. Bartonella DNA was detected in 102 (23.7%) small mammals, 44 (29.1%) fleas and five (3.7%) pooled tick samples. Sequence analysis of 16S-23S rRNA ITS region showed that sequences were identical or similar to Bartonella grahamii, Bartonella taylorii and Bartonella rochalimae. This study is the first investigating the distribution and diversity of Bartonella species in small mammals and their ectoparasites in Lithuania. B. grahamii, B. taylorii, and B. rochalimae were detected in small mammals and their fleas, and B. grahamii in ticks obtained from small mammals.
巴尔通体病原体是一种新出现的人畜共患病原体。全球流行病学研究表明，小型哺乳动物是巴尔通体属的储存宿主，其体外寄生虫是潜在的传播媒介。本研究的目的是调查立陶宛小型哺乳动物（啮齿目、食虫目）及其体外寄生虫（跳蚤和蜱）中巴尔通体感染的流行情况。2013年至2014年期间，在立陶宛用活捕陷阱捕获了代表9个物种的430只小型哺乳动物。从109只（25.8%）小型哺乳动物身上收集了代表8个物种的151只跳蚤。从68只（16.1%）小型哺乳动物身上收集了570只蜱（蓖麻硬蜱）。在102只（23.7%）小型哺乳动物、44只（29.1%）跳蚤和5份（3.7%）混合蜱样本中检测到巴尔通体DNA。16S - 23S rRNA ITS区域的序列分析表明，序列与格雷厄姆巴尔通体、泰勒巴尔通体和罗沙利马巴尔通体相同或相似。本研究是首次调查立陶宛小型哺乳动物及其体外寄生虫中巴尔通体物种的分布和多样性。在小型哺乳动物及其跳蚤中检测到格雷厄姆巴尔通体、泰勒巴尔通体和罗沙利马巴尔通体，在从小型哺乳动物身上采集的蜱中检测到格雷厄姆巴尔通体。
