Abstract:

Objective

To assess the representativeness and accuracy of consensus sequence generated from Next-generation sequencing (NGS) for human immunodeficiency virus (HIV) quasispecies.

Methods

Total of 32 blood samples from 29 patients with HIV infection were collected. Among them, 3 blood samples were collected from 3 patients when virologic failure occurred. HIV DNA pol gene was amplified and sequenced by Sanger sequencing and NGS sequencing, respectively. The sequencing data of Sanger and NGS were processed by Sequencher (v4.10.1) and Bowtie2 (v2.2.5) separately. Furtherly, the consensus sequence from NGS was defined by the homemade PERL scripts. Finally, cluster analysis was processed by Mega software and the different sites between the consensus sequence of NGS and Sanger sequencing were identified and analyzed, respectively.

Results

Cluster analysis showed that 90.6% (29/32) sequences derived from the same sample were clustered in the same branch, the average credibility was 95.5%. The accuracy of each nucleotide site in consensus sequences was 99.6% compared to Sanger sequencing. Furthermore, the 81.6% (155/190) nucleotide type of inconsistent sites was transition, and the transition between Guanine (G) and Adenine (A) was the most common with the occurrence ratio of 39% (74/190).

Conclusions

The consensus sequence of NGS sequencing could be used in the study of HIV dominant quasispecies, which could present the high accurate results with Sanger sequencing.
