[Objective] To establish a new molecular method for simultaneous and rapid detection and confirmation of Ebola virus by using sequence analysis combined with pyrosequencing technology. [Methods] Amplification primers and a sequencing primer were designed according to the published sequences of conserved L gene regions of three Sudan Ebola viruses in GenBank. A gene sequence was synthesized artificially, and the target gene were amplified by PCR, to prepare cRNA through in vitro transcription. RT-PCR was developed for conserved regions of the gene, and the RT-PCR products were pysrosequenced.[Results] The characterized nucleotide segment was obtained by sequence analysis, and then the segment was confirmed as Sudan Ebola virus. Compared to the Sanger method of Huada, they showed 100% agreement.[Conclusion] Pyrosequencing technology based on sequence analysis can be used to confirm Sudan Ebola virus.
