Abstract

Phlebotomine sand flies (Diptera: Psychodidae) are the principal vectors of phleboviruses and spp., the causative agents of leishmaniases. The Mediterranean sand fly fauna is diverse, and leishmaniasis, mainly caused by is endemic in the Balkan countries. Despite recent entomological surveys, only some districts of Kosovo have been sampled for sand flies, with no proof/confirmation of . This study aimed to gain further insights into the species composition of natural sand fly populations in previously unsampled districts and areas in Kosovo without reports of leishmaniasis and to detect DNA in sand flies. A sand fly survey was conducted in 2022 in all seven districts of Kosovo. Collected females were screened for DNA by PCR. Positive samples were sequenced and subjected to maximum likelihood analysis with reference sequences for further molecular characterization. The trapping activities at 114 different localities resulted in 3272 caught specimens, comprising seven sand fly species of two genera, namely , , , , , and . DNA was detected in three individual sand flies of and This study provides the most extensive sand fly survey in Kosovo and reports the first record of DNA in sand flies, indicating autochthonous circulation of .

摘要

白蛉(双翅目:毛蠓科)是白蛉病毒和利什曼原虫属物种的主要传播媒介,利什曼原虫属是利什曼病的病原体。地中海地区的白蛉种类多样,主要由硕大利什曼原虫引起的利什曼病在巴尔干国家呈地方性流行。尽管最近进行了昆虫学调查,但科索沃只有一些地区对白蛉进行了采样,没有关于硕大利什曼原虫的证据/确认报告。本研究旨在进一步深入了解科索沃以前未采样的、没有利什曼病报告的地区自然白蛉种群的物种组成,并检测白蛉体内的硕大利什曼原虫DNA。2022年在科索沃的所有七个地区进行了白蛉调查。通过聚合酶链反应(PCR)对采集的雌性白蛉进行硕大利什曼原虫DNA筛查。对阳性样本进行测序,并与参考序列进行最大似然分析,以进行进一步的分子特征分析。在114个不同地点的诱捕活动共捕获了3272只标本,包括两个属的七种白蛉,即长管白蛉属、白蛉属、司蛉属、异白蛉属、硕大白蛉指名亚种、中华白蛉和吴氏白蛉。在硕大白蛉指名亚种和中华白蛉的三只个体白蛉中检测到了硕大利什曼原虫DNA。本研究提供了科索沃最广泛的白蛉调查,并报告了白蛉体内硕大利什曼原虫DNA的首次记录,表明硕大利什曼原虫在当地循环传播。
