Abstract

Based on findings in small RNA-sequencing (Seq) data analysis, we developed highly sensitive and specific real-time reverse transcription (RT)-PCR assays with locked nucleic acid probes targeting the abundantly expressed leader sequences of Middle East respiratory syndrome coronavirus (MERS-CoV) and other human coronaviruses. Analytical and clinical evaluations showed their noninferiority to a commercial multiplex PCR test for the detection of these coronaviruses.

Schematic diagram of the MERS-CoV genome, with the leader sequence at the 5′-untranslated region enlarged to illustrate the abundance of the small RNA sequences. The percentages of mapped small RNA sequence reads at the leader sequence, ORF1a, S, and N gene regions are quantified and shown. Leader sequences of 70 to 72 nucleotides in length are also present in other human coronaviruses (HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1).
