Molecular basis of mammalian transmissibility of avian ...

This virus did not transmit via the airborne route, suggesting that markers in NS1 and NEP are important, but not sufficient, for mammalian airborne transmissibility (Fig. 1 F and G). To determine if any mutations were present in viruses that trans-mitted by direct contact (DC) or by airborne contact (AC), we se- ................
