Clinical protection of rTS-gB against virulent ILTV challenge in chickens. Four-week-old SPF chickens were vaccinated with rTS-gB, K317, or PBS and challenged with the virulent ILTV WG strain at 14 dpi. The clinical signs were recorded daily, and the body weights were measured prior to challenge and at 10 dpc. The average clinical scores for each group of chickens (A) and the percentage of weight gain from prior to challenge to 10 dpc (B) were plotted. * p < 0.05; ** p < 0.01. *** p < 0.001. ns, not significant.
