The deer ked (Lipoptena cervi) is a haematophagous ectoparasite of cervids that harbours haemotrophic Bartonella. A prerequisite for the vector competence of the deer ked is the vertical transmission of the pathogen from the mother to its progeny and transstadial transmission from pupa to winged adult. We screened 1154 pupae and 59 pools of winged adult deer keds from different areas in Finland for Bartonella DNA using PCR. Altogether 13 pupa samples and one winged adult deer ked were positive for the presence of Bartonella DNA. The amplified sequences were closely related to either B. schoenbuchensis or B. bovis. The same lineages were identified in eight blood samples collected from free-ranging moose. This is the first demonstration of Bartonella spp. DNA in a winged adult deer ked and, thus, evidence for potential transstadial transmission of Bartonella spp. in the species.
鹿虱(Lipoptena cervi)是一种吸血的外寄生虫,它携带血液病原体巴尔通体。鹿虱作为媒介的前提条件是病原体从母代垂直传播给后代,以及从蛹到有翼成虫的转期传播。我们使用 PCR 技术从芬兰不同地区的 1154 个蛹和 59 个有翼成虫鹿虱群体中筛选巴尔通体 DNA。共有 13 个蛹样本和 1 个有翼成虫鹿虱的巴尔通体 DNA 呈阳性。扩增序列与 B. schoenbuchensis 或 B. bovis 密切相关。在从自由放养的驼鹿身上采集的 8 份血液样本中也鉴定出了相同的谱系。这是首次在有翼成虫鹿虱中发现巴尔通体 spp. DNA,因此为该物种中巴尔通体 spp. 的潜在转期传播提供了证据。
