New real-time reverse transcriptase polymerase chain reactions facilitate detection and differentiation of novel A/H1N1 influenza virus in porcine and human samples.

Abstract excerpt

Influenza A viruses are maintained as a quasispecies cloud in several natural host reservoirs of avian as well as mammalian species. Accidental host exposure, selection and further adaptation of individual influenza A viruses during sporadic trans-species transmission may eventually lead to the establishment of new, stably circulating lineages in a new, possibly mammalian, host species. Given a high...
