Comparision of viremia levels between bac-GX0101 and GX0101ΔMeq infected SPF chickens (n = 6)

Days post-infection	Viremia (PFU/ml)
	bac-GX0101	GX0101ΔMeq
7	28 ± 9.8 a	32 ± 6.2 a
14	154 ± 47.6a	69.7 ± 16.5 b
21	256.5 ± 46.8 a	78.2 ± 9.5 b

All chickens were inoculated with 1000 PFU of the indicated virus by a subcutaneous route. The difference in vivo replication between bac-GX0101 and GX0101ΔMeq was determined by viremia levels. The numbers in the table indicate: mean ± standard deviation, at days 7, 14 and 21 p.i., and same letters indicate that the differences were not significant (P > 0.05), different letters indicate that a significant difference (P < 0.05).
