Novel Swine Influenza Virus Reassortants in Pigs, China

摘要

During swine in. uenza virus surveillance in pigs in China during 2006–2009, we isolated subtypes H1N1, H1N2, and H3N2 and found novel reassortment between contemporary swine and avian panzootic viruses. These re-assortment events raise concern about generation of novel viruses in pigs, which could have pandemic potential.
