摘要

位于西西伯利亚南部的托木斯克地区是蜱传疾病的高风险地区之一,因为人类中蜱传脑炎和莱姆病的发病率升高。野生鸟类可被认为是蜱传病原体的宿主之一,也是受感染蜱的宿主之一。野生鸟类的高度流动性导致蜱传病原体向新的地理区域传播的不可预测的可能性。本研究的主要目的是评估蜱传病原体在野生鸟类和以其为食的蜱中的流行情况,并确定不同种类的鸟类在维持蜱传感染疫源地中的作用。采用RT-PCR/ PCR和酶免疫分析法,对采集的野生鸟类443只(60种)和野蜱378只(1795只)进行蜱传病原体检测,分别为蜱传脑炎病毒(TBEV)、西尼罗病毒(WNV)和疏螺旋体、立克次体、埃利希体、无形体、巴尔通体和巴贝虫(1893年)。在43种鸟类中检测到一种或多种蜱传感染标志物。所有标记物均在野外鸟Turdus pilaris Linnaeus、布氏苇莺Acrocephalus dumetorum Blyth、普通红尾鸲Phoenicurus Phoenicurus (Linnaeus)和普通苍头燕雀Fringilla coelebs Linnaeus中检测到。虽然在鸟类和蜱中已鉴定出所有病原体,但我们发现在大多数情况下(75.5%),从鸟类和蜱中采集的病原体存在不匹配。野生鸟类及其蜱虫可能在蜱传病原体在不同地理区域的传播中起着极其重要的作用。

Detection of tick-borne pathogens in wild birds and their ticks in Western Siberia and high level of their mismatch.

The Tomsk region located in the south of Western Siberia is one of the most high-risk areas for tick-borne diseases due to elevated incidence of tick-borne encephalitis and Lyme disease in humans. Wild birds may be considered as one of the reservoirs for tick-borne pathogens and hosts for infected ticks. A high mobility of wild birds leads to unpredictable possibilities for the dissemination of tick-borne pathogens into new geographical regions. The primary goal of this study was to evaluate the prevalence of tick-borne pathogens in wild birds and ticks that feed on them as well as to determine the role of different species of birds in maintaining the tick-borne infectious foci. We analysed the samples of 443 wild birds (60 species) and 378 ticks belonging to the genus Ixodes Latraille, 1795 collected from the wild birds, for detecting occurrence of eight tick-borne pathogens, the namely tick-borne encephalitis virus (TBEV), West Nile virus (WNV), and species of Borrelia, Rickettsia, Ehrlichia, Anaplasma, Bartonella and Babesia Starcovici, 1893, using RT-PCR/or PCR and enzyme immunoassay. One or more tick-borne infection markers were detected in 43 species of birds. All markers were detected in samples collected from fieldfare Turdus pilaris Linnaeus, Blyth's reed warbler Acrocephalus dumetorum Blyth, common redstart Phoenicurus phoenicurus (Linnaeus), and common chaffinch Fringilla coelebs Linnaeus. Although all pathogens have been identified in birds and ticks, we found that in the majority of cases (75.5 %), there were mismatches of pathogens in birds and ticks collected from them. Wild birds and their ticks may play an extremely important role in the dissemination of tick-borne pathogens into different geographical regions.

期刊介绍: FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
