ABSTRACT Dermanyssus gallinae , the poultry red mite is an obligatory blood-sucking ectoparasite and has been involved in the transmission of several pathogens between both animals and humans. In order to develop effective control strategies against D. gallinae, it is essential to determine their genetic compositions and investigate the potential vector roles of these mites. Therefore, we aimed to analyse the mt-COI gene regions of D. gallinae populations and investigate avian haemosporidian parasites in order to point out their risk potentials for the presence of possible transmission by these mites. In total, 1985 mites were collected from five laying hen breeding facilities in Central Anatolia Region in Turkey. The mt-COI sequence analyses of 100 individual mites identified 6 haplotypes (TD1 to TD6) in three haplogroups. Although the local lineages are common in the region, our findings also support the possibility of international transmission of D. gallinae. A total of 126 pools of D. gallinae were screened for investigation of three genera of avian haemosporidians. In total, five pools from three facilities were identified as positive for species of Plasmodium. These findings provide novel molecular data on the possible vector role of D. gallinae in the transmission of avian haemosporidians and draw attention to the risk potentials in poultry farms.

土耳其家禽红螨、Dermanyssus gallinae 谱系的分子特征和螨种群中疟原虫物种的首次报告

摘要鸡皮螨，家禽红螨是一种必须吸血的体外寄生虫，并且参与了多种病原体在动物和人类之间的传播。为了制定有效的鸡 D. 控制策略，必须确定它们的遗传组成并研究这些螨的潜在载体作用。因此，我们旨在分析 D. gallinae 种群的 mt-COI 基因区域并调查鸟类血孢子虫寄生虫，以指出它们可能存在这些螨虫传播的风险。总共从土耳其安纳托利亚中部地区的五个蛋鸡育种设施收集了 1985 只螨虫。对 100 个个体螨虫的 mt-COI 序列分析在三个单倍群中鉴定了 6 个单倍型（TD1 到 TD6）。尽管当地谱系在该地区很常见，但我们的研究结果也支持 D. gallinae 国际传播的可能性。总共筛选了 126 个 D. gallinae 池，用于调查三个属的禽血孢子虫。总共有来自三个设施的五个池被确定为疟原虫阳性。这些发现为 D. gallinae 在禽血孢子虫传播中的可能载体作用提供了新的分子数据，并引起了人们对家禽养殖场潜在风险的关注。来自三个设施的五个池被确定为疟原虫阳性。这些发现为 D. gallinae 在禽血孢子虫传播中的可能载体作用提供了新的分子数据，并引起了人们对家禽养殖场潜在风险的关注。来自三个设施的五个池被确定为疟原虫阳性。这些发现为 D. gallinae 在禽血孢子虫传播中的可能载体作用提供了新的分子数据，并引起了人们对家禽养殖场潜在风险的关注。
