使用Coriolis空氣采樣器優(yōu)化檢測(cè)病毒、細(xì)菌和真菌
在巖石圈(土壤)、水圈(水)和大氣(空氣)這三個(gè)行星生物圈中,對(duì)大氣微生物含量的研究最少,這是非常反常的,主要原因是將大氣作為微生物棲息的生態(tài)系統(tǒng)進(jìn)行研究多年來一直是一項(xiàng)技術(shù)挑戰(zhàn)。[1]
自2010年以來,Coriolis空氣采樣器已越來越多地用于多個(gè)領(lǐng)域,從學(xué)術(shù)研究到獸醫(yī)、醫(yī)療保健和職業(yè)危害評(píng)估等。用于檢測(cè)病毒、細(xì)菌和真菌,通過使用培養(yǎng)、多重PCR、qPCR和RT-ddPCR、宏基因組學(xué)、顯微鏡、微流控細(xì)胞術(shù)和LC-MS/MS等多種技術(shù)分析Coriolis采集的樣本。而用于檢測(cè)空氣中微生物的應(yīng)用數(shù)量仍在不斷增加,還有很多優(yōu)化的空間。
感謝Coriolis在世界各地的用戶發(fā)表了300多份出版文獻(xiàn),我們從中能夠?qū)W習(xí)到一些更好的采樣策略和方案,以此改進(jìn)我們的技術(shù)和技術(shù)支持。從這些文獻(xiàn)中,bertin科學(xué)家選擇了三篇對(duì)優(yōu)化收集空氣樣品高質(zhì)量的開源研究論文,用于優(yōu)化Coriolis生物空氣采樣器檢測(cè)病毒、細(xì)菌和真菌,向所有科研人員表示衷心的感謝!
