DESCRIPTION (provided by applicant): Viral infections have a major impact on public health both domestically and worldwide. Consequently intense effort has been placed on the study of known human viral pathogens. However, it is likely that many diseases of unknown etiology are caused by viruses. Furthermore, new viral pathogens are constantly emerging. The ability to detect and identify novel human viruses is a major roadblock to understanding and curing diseases associated with these agents. We have developed a collaborative approach that combines the power of viral metagenomics with advances in microfluidics to allow the detection and isolation of individual viruses from complex biological samples. Here, metagenomics is the study of large populations of unknown viruses, while microfluidics is the application of small scale structuring to control fluid flow. This application seeks support to broaden the types of viruses detected by this system and to apply it to the isolation and preliminary characterization of two novel viruses that potentially infect humans. The development of this platform will greatly enhance the ability to detect, isolate and thus rapidly characterize novel pathogens. The development of the microfluidics platform will provide emerging technology to the identification and study of heretofore unidentified viruses. This study will be the first effort to apply this technology to the identification of important new classes of viruses. This work represents a novel combination of two methods to advance the discovery process of new viruses that have a major impact on human health.

描述（由申请人提供）：病毒感染对国内和全球的公共卫生产生重大影响。因此，人们对已知人类病毒病原体的研究投入了大量精力。然而，许多病因不明的疾病很可能是由病毒引起的。此外，新的病毒病原体不断出现。检测和识别新型人类病毒的能力是理解和治疗与这些病毒相关的疾病的主要障碍。我们开发了一种协作方法，将病毒宏基因组学的力量与微流体的进步相结合，从而能够从复杂的生物样本中检测和分离单个病毒。在这里，宏基因组学是对大量未知病毒的研究，而微流体学是应用小规模结构来控制流体流动。该申请寻求支持以扩大该系统检测到的病毒类型，并将其应用于两种可能感染人类的​​新型病毒的分离和初步表征。该平台的开发将大大增强检测、分离并快速表征新型病原体的能力。微流控平台的发展将为迄今为止未识别的病毒的识别和研究提供新兴技术。这项研究将是首次将该技术应用于识别重要的新病毒类别。这项工作代表了两种方法的新颖组合，以推进对人类健康产生重大影响的新病毒的发现过程。
