From: Protection conferred by a recombinant Marek’s disease virus that expresses the spike protein from infectious bronchitis virus in specific pathogen-free chicken

Groups Bodyweight (g)*
  1-day-old Pre-challenge Post-challenge
rMDV-S1 49.5 ± 0.8 a (n = 20) 259.6 ± 10.9 a (n = 20) 433.0 ± 29.8 a (n = 19)
CVI988/Rispens 49.4 ± 0.7 a (n = 20) 256.6 ± 11.4 a (n = 20) 395.7 ± 48.7 b (n = 14)
PBS 49.5 ± 1.1 a (n = 20) 258.8 ± 10.9 a (n = 20) 391.6 ± 50.9 b (n = 14)
  1. * Mean ± SE. Bodyweight among the four experimental groups, as indicated by different lowercase letters, differed significantly based on χ2 analysis (p < 0.05).
