Human H7N9 Influenza A Viruses Replicate in Swine Respiratory Tissue Explants

Abstract excerpt

Recently, novel H7N9 influenza viruses have caused an unprecedented outbreak in humans. Pigs are an important intermediate host for influenza; thus, we assessed the replication ability of three human H7N9 viruses (A/Anhui/1/2013, A/Shanghai/1/2013, A/Shanghai/2/2013) in swine tissue explants. All viruses tested replicated efficiently in explants from tracheas and bronchi, with limited replication in alveolar...
