病毒種屬鑒別靶向治療基因檢測臨床應(yīng)用結(jié)果

宏基因組鳥槍法測序 (MSS) 是表征病毒種群的重要工具。它獨立于培養(yǎng)，不需要樣本中病毒的先驗知識，并且可以提供有用的基因組信息。然而，MSS 可能缺乏敏感性，并且可能產(chǎn)生的數(shù)據(jù)不足以進(jìn)行詳細(xì)分析。我們創(chuàng)建了一個靶向序列捕獲面板 ViroCap，旨在從感染脊椎動物宿主的 34 個家族的 DNA 和 RNA 病毒中富集核酸。一種計算方法將約 10 億 bp 的病毒參考序列壓縮成 <2 億 bp 的獨特的、具有代表性的序列，適用于靶向序列捕獲。我們比較了在標(biāo)準(zhǔn) MSS 中檢測病毒與靶向序列捕獲后的 MSS 中檢測病毒的有效性。首先，我們分析了兩組樣本，一組來自提交給診斷病毒學(xué)實驗室的樣本，另一組來自兒童發(fā)燒研究中收集的樣本。我們在兩組中檢測到 14 和 18 種病毒，包括來自 10 個科的 19 個屬，在捕獲富集后顯著增強了基因組表示。捕獲后病毒讀數(shù)百分比的中位數(shù)增加倍數(shù)分別為 674 和 296。先進(jìn)組捕獲后的中位覆蓋廣度從 2.1% 增加到 83.2%，第二組從 2.0% 增加到 75.6%。接下來，我們分析了包含一組不同的指環(huán)病毒序列的樣本，并證明 ViroCap 可用于檢測與用于選擇捕獲探針的參考相比變異高達(dá) 58% 的病毒序列。 ViroCap 顯著增強了一套全面病毒的 MSS，并具有研究和臨床應(yīng)用的實用性。
