Whole-Genome Sequencing Protocols for IBV and Other Coronaviruses Using High-Throughput Sequencing

Abstract

This chapter reports the high-throughput sequencing protocol for sequencing Coronaviruses and other positive strand viruses to produce a dataset of significant depth of coverage. The protocol describes sequencing of infectious bronchitis virus propagated in embryonated eggs and harvested in the allantoic fluid. The protocol is composed of three main steps—enrichment of the allantoic fluid using ultracentrifugation, extraction of total RNA from allantoic fluid, and library preparation from total RNA to DNA sequencing libraries. The workflow will be suitable for all coronaviruses using high-throughput sequencing platforms.
