概括

西尼罗河病毒 (WNV) 暴露在西班牙野生子和伊比利亚子中首次被检测出来. 这些形动物可以作为在地中海生态系统中WNV监测的哨兵.

科学领域:

兽医病毒学兽医病毒学
野生动物流行病学
亚博病毒学亚博病毒学

背景情况:

西尼罗河病毒 (WNV) 是蚊子传播的广泛传播的黄斑病毒,在欧洲引起了严重的公众和动物健康问题.
目前,WNV已经蔓延到欧洲,在西班牙的各种野生哺乳动物身上有记录.
之前没有对野生形动物的WNV进行过血清流行病学研究.

研究的目的:

评估欧洲野生子 (Oryctolagus cuniculus) 和伊比利亚子 (Lepus granatensis) 种群的西尼罗病毒 (WNV) 暴露情况.
调查西班牙地中海生态系统的形动物中的WNV血清流行.

主要方法:

收集了来自西班牙安达卢西亚106个狩猎场的540只野生形动物 (399只子,141只子) 的血清.
在2018/2019和2022/2023狩猎季之间进行了血清学分析.
使用阻断酶相关的免疫吸收试验 (bELISA) 和病毒微中和试验.

主要成果:

在5.0%的形动物中检测到flavivirus抗体;在4.8%的野生子和0.7%的伊比利亚子中证实了WNV暴露.
在安达卢西亚西部的三处狩猎场所发现了WNV阳性形动物,与WNV大爆发相吻合.
在被研究的人群中证实没有乌苏图病毒和巴加扎病毒抗体.

结论:

这项研究报告了西班牙野生子和全球的伊比利亚子中WNV暴露的第一个证据.
野生子和伊比利亚子可能不是主要宿主,但可以作为WNV监测的宝贵哨兵.
这些形动物种群为监测伊比利亚地中海生态系统中的WNV动态提供了潜力.

关键词:

Arboviral Encephalitis

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Encephalitis l: Introduction

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
