Background: Next generation sequencing (NGS) is a new technology that can be used for broad detection of infectious pathogens and is rapidly becoming an essential platform in clinical laboratories. It is not known how NGS will displace or enhance gold standard methodologies in infectious disease diagnosis. Objectives: To investigate the feasibility and application of NGS technology in public health laboratories and compare NGS technology with conventional methods. Study design: Illumina MiSeq system was used to detect viral pathogens alongside other conventional virology methods using typical clinical specimen matrices. Sixteen clinical specimens and two CDC proficiency panels containing seventeen specimens were analyzed. Results: Known pathogenic viral nucleic acid was positively identified in all clinical specimens, correlating and building upon results obtained by more conventional laboratory methods. Sequencing depths ranged from 0.008X to 319 and genome coverage ranged from 0.6% to 99.9%. To substantiate the described methods used to analyze data derived from clinical specimens, the results of a clinical proficiency panel are also presented. Discussion: Our results reveal true scarcity of known pathogenic viral nucleic acids in clinical specimens. NGS outperforms more conventional detection methods in this study by turnaround time as well as the improved depth of knowledge in regards to serotyping and drug resistance. (C) 2016 Elsevier B.V.
