2017-2019年浙江省衢州市城区公园蜱分布及携带病原体情况调查

Status of tick distribution and tick-borne pathogens in urban parks of Quzhou, Zhejiang, 2017–2019

  • 摘要:
      目的  了解浙江省衢州市城区公园蜱类的种群分布和病原体携带情况,评估衢州市城区公园蜱传疾病的传播风险。
      方法  2017 — 2019年每年3 — 11月,选择衢州市6个县(市、区)共18家城区公园,利用人工布旗法和动物体表采集法采集游离蜱和寄生蜱,进行蜱种鉴定,采用PCR方法检测蜱体内伯氏疏螺旋体、斑点热群立克次体、微小巴贝西虫、无形体/埃立克体、发热伴血小板减少综合征布尼亚病毒(SFTSV)。
      结果  共捕获蜱168只,春、夏、秋季分别采集蜱标本41、70、57只,季节间无明显差异;168只蜱均为成蜱,隶属于1科5属7种,以革蜱为主,其次为长角血蜱、中华硬蜱,分别占36.90%(62/168)、26.79%(45/168)、占14.29%(24/168);游离蜱39只(23.21%),寄生蜱129只(76.79%),其中宿主为鼠类的有96只(74.42%),远高于其他宿主;其中47只检测5类病原体阳性,总阳性率为27.98%;以伯氏疏螺旋体阳性率最高(13.10%),无形体/埃立克体阳性率最低(1.79%)。
      结论  衢州市城区公园捕获蜱类以革蜱和长角血蜱为主,携带伯氏疏螺旋体、斑点热群立克次体、SFTSV等病原体。 市民存在被蜱叮咬及感染蜱传疾病的风险。

     

    Abstract:
      Objective  To understand the distribution and pathogen carriage of ticks in urban parks of Quzhou of Zhejiang province, and evaluate the transmission risk of tick-borne diseases in the urban parks.
      Methods  From March to November during 2017−2019, a total of 18 urban parks in 6 counties (districts) of Quzhou were selected. The free ticks and parasitic ticks were collected by mannual lab-cloth flag method and animal surface collection method, and the tick species were identified. Borrelia burgdorferi, spotted fever group Rickettsia, Babesia microsatellite, Anaplasmosis/Eriksiella and severe fever with thrombocytopenia syndrome bunyavirus in ticks were detected by PCR.
      Results  A total of 168 ticks were captured, and 41, 70 and 57 ticks were collected in spring, summer and autumn, respectively, the differences were not significant. All the 168 ticks were adult ticks, belonging to 7 species, 5 genera and 1 family. Dermacentor was predominant, accounting for 36.90%(62/168), followed by Haemaphysalis longicornis, accounting for 26.79%(45/168), Ixodes sinensis, accounting for 14.29%(24/168). There were 39 free ticks (23.21%) and 129 parasitic ticks (76.79%), in which 96 had rodents as host (74.42%), higher than other hosts. A total of 47 ticks were positive for five pathogens, and total positive rate was 27.98%, Among them, the positive rate of Borrelia burgdorferi was highest (13.10%), and the positive rate of Anaplasma/Eriksium was lowest(1.79%).
      Conclusion  Dermacentor and H.longicornis were the main species of ticks captured in urban parks of Quzhou, carrying Borrelia burgdorferi, spotted fever group Rickettsia, severe fever with thrombocytopenia syndrome bunyavirus and other pathogens, the risk of tick bite and infection exists for the public.
