Figures & data

Figure 1. Organization index of infected and control groups of different breeds at different times. S: spleen; T: thymus; B: bursa of fabricius. P: Pengxian yellow chicken; T: Tibetan chicken; A: Avian broilers. All values are represented as the mean ± SEM (n = 3). (*) represents statistical significance (P < 0.05).

Figure 5. Pathway enrichment analyses of DEPs in spleens of three breeds. A: 15AC-VS-15PC; B: 15AC-VS-15 TC; C: 15PC-VS-15 TC. The enrichment factor is the number of DEPs annotated to the pathway divided by all of the identified proteins annotated to the pathway. The higher the value, the higher the proportion of differentially expressed proteins annotated to this pathway. The dot size in the figure represents the number of DEPs annotated to this pathway.
