[Abstract]  Many RNA viruses are found in protozoan parasites. They can be responsible for more serious pathology or treatment failure. For the detection of viral double-stranded RNA (dsRNA), sequence-dependent and -independent methods are available, such as quantitative real-time PCR and immunofluorescence, dot blot, ELISA or sequencing. The technique presented here is sequence-independent and is well detailed in the following protocol, taking the example of Leishmania RNA virus (LRV) in Leishmania guyanensis (Lgy) species. To summarise, the protocol is divided into four major steps: RNA extraction from the parasites, RNA purification, enzymatic digestions with DNase I and Nuclease S1, and visualization by gel electrophoresis. This method can be used to detect other viral ... [摘要]  [摘要 ] 原生动物寄生虫中发现了许多RNA病毒,它们可能导致更严重的病理或治疗失败。对于病毒双链RNA(dsRNA)的检测,有序列依赖性和非依赖性方法,例如定量实时PCR和免疫荧光,斑点印迹,ELISA或测序。此处介绍的技术是与序列无关的,并且在以下协议中进行了详细说明,以利什曼原虫(Legymania guyanensis)(Lgy )中的利什曼原虫RNA病毒(LRV)为例 概括地说,该协议分为四个主要步骤:从寄生虫中提取RNA,RNA纯化,使用DNase I和Nuclease S1进行图解消化以及通过凝胶电泳进行可视化。该方法可用于检测其他病毒dsRNA它提供了一个额外的工具,可以对先前引用的其他技术进行补充,并且很容易实现。

[背景 ] 广泛的多样性RNA病毒中存在的原生动物寄生虫一直都有详细记载(王和王,1991;戈什等人,2011;桑戈等人。2014;碱液等人,2016年Akopyants 等人2016 ; Fernandez- Presas 等人,2017; Grybchuk 。等人。,2018)。此外,这些病毒已经被描述为潜在的毒力因子(Fichorova 等人,2013; EL- Gayar 。等人,2016; 拉特等。,2019)特别值得注意的,存在的内共生体。利什曼原虫RNA病毒(LRV),A ...
