概括

禽类复原病毒 (ARV) 导致家禽关节炎. 这项研究将病变严重程度与病毒RNA水平联系起来,将纤维细胞识别为受感染的细胞,并验证在ARV诊断和致病研究的现场杂交 (ISH).

科学领域:

兽医病理学兽医病理学
分子诊断学分子诊断
鸟类传染病鸟类传染病

背景情况:

禽类转录病毒 (ARV) 是禽类病毒性关节炎/关节炎的致病原体.
由于非特异性病变和缺乏标准化的方法,ARV诊断具有挑战性.
定量实时逆转录酶聚合酶链反应 (qRT-PCR) 和现场杂交 (ISH) 是关键的诊断工具.

研究的目的:

在家禽中研究病变严重程度和ARVRNA水平之间的关系.
支持使用qRT-PCR和ISH进行ARV检测和分析.
确定感染ARV的特定细胞类型.

主要方法:

分析51例疑似ARV病因的家禽病例,包括临床,组织学和分子评估.
组织学分数测定了紧张突炎的严重程度 (炎症,突增殖,纤维化等). ) 的情况.
在受影响的肌组织上使用qRT-PCR和RNAScope ISH检测ARVRNA.

主要成果:

与阴性病例相比,ARV阳性病例表现出明显更高的组织学得分.
在33.3%的qRT-PCR阳性病例中,ISH检测到同胞细胞和亚极纤维细胞中的病毒转录.
阳性ISH结果与较低的qRT-PCR Ct值和较高的损伤得分相关.

结论:

这项研究与ARV感染中的病毒转录水平联系了紧突炎病变的严重程度.
纤维细胞被确定为ARV感染的关键细胞类型.
ISH是ARV诊断和研究其在家禽中的病变发生的一个有价值的工具.

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...
