新出现的病毒通常在世界热带和亚热带地区流行,但全球旅行的增加、气候变化和生活方式的变化被认为有助于这些病毒传播到新的地区。这些病毒中的许多引起与其他新出现的病毒或常见感染相似的疾病症状,使得这些意想不到的病原体难以诊断。含有所有测序病毒和细菌探针的广谱病原体检测微阵列可以快速识别病毒,指导治疗和适当病例管理的决策。我们报告了一种改进的全转录组扩增(WTA)方法,该方法增加了无偏扩增,特别是RNA病毒。使用这种改进的WTA方法,我们使用两种不同的微阵列数据分析方法测试了劳伦斯利弗莫尔微生物检测阵列(LLMDA)对非临床和临床样本中存在的各种新出现病毒的特异性和灵敏度。
Emerging viruses are usually endemic to tropical and sub-tropical regions of the world, but increased global travel, climate change and changes in lifestyle are believed to contribute to the spread of these viruses into new regions. Many of these viruses cause similar disease symptoms as other emerging viruses or common infections, making these unexpected pathogens difficult to diagnose. Broad-spectrum pathogen detection microarrays containing probes for all sequenced viruses and bacteria can provide rapid identification of viruses, guiding decisions about treatment and appropriate case management. We report a modified Whole Transcriptome Amplification (WTA) method that increases unbiased amplification, particular of RNA viruses. Using this modified WTA method, we tested the specificity and sensitivity of the Lawrence Livermore Microbial Detection Array (LLMDA) against a wide range of emerging viruses present in both non-clinical and clinical samples using two different microarray data analysis methods.
