Abstract

The complete genomic sequences of H5N1 highly pathogenic avian influenza (HPAI) viruses were directly obtained from lung, trachea, and colon tissues and an intestinal fecal sample of a patient by using the next-generation sequencing technique. This is the first report on complete H5N1 viral genomes from human autopsy specimens.

Highlights

  • The H5N1 highly pathogenic avian influenza Orthomyxoviridae

  • Autopsy samples were collected by a pathologist using the standard technique for routine histologic analysis

  • Total RNA was extracted from all specimens by using TRIzol reagent (Invitrogen, Carlsbad, CA) and was further subjected to cDNA synthesis by using the SuperScript III first-strand synthesis system (Invitrogen)

Summary

Introduction

The H5N1 highly pathogenic avian influenza Orthomyxoviridae. It is an enveloped virus (HPAI) virus belongs to the with an eight-segmented, family singlestranded RNA genome of negative polarity, with a length of about 13.5 kb in total. Autopsy samples were collected by a pathologist using the standard technique for routine histologic analysis. These samples were stored frozen at Ϫ80°C until used. Total RNA was extracted from all specimens by using TRIzol reagent (Invitrogen, Carlsbad, CA) and was further subjected to cDNA synthesis by using the SuperScript III first-strand synthesis system (Invitrogen).
