Changes in nonstructural protein 3 are associated with attenuation in avian coronavirus infectious bronchitis virus	2011-09-10		.txt	text/plain	6285	243	52	The percent amino acid identity for the S glycoprotein is 97.8% for Ark viruses, 96.6% for GA98 viruses, and 97.2% for Mass 41 viruses (Fig. 3) . To examine the sequence changes in individual genes associated with attenuation of IBV for chickens, we sequenced and compared the full-length consensus genomes of pathogenic IBV viruses and egg-passaged attenuated (for chickens) viruses from three different serotypes.	cache/cord-272693-432ixb7g.txt	txt/cord-272693-432ixb7g.txt
