Figure 5From: Design, development, and evaluation of the efficacy of a nucleic acid-free version of a bacterial ghost candidate vaccine against avian pathogenic E. coli (APEC) O78:K80 serotypeLesion scoring in immunized and non-immunized groups of chicken after challenge with the wild type E. coli O78:K80. The lesion scoring for every carcass was performed for air sacs, heart, and liver as described in “Materials and methods” section. The statistically significant differences between groups are shown as ****p ≤ 0.0001 and *p ≤ 0.05.Back to article page
