Global DEGs identified between the MG infection group and control group in chicks and chicken embryos. Volcano plots of DEGs between the two groups in chicken embryos (a) and chicks (b). Blue dots indicate significantly up-regulated genes (Log₂ FC > 1.5 and adjusted-p value < 0.05); orange dots indicate significantly down-regulated genes (Log₂ FC < 1.5 and adjusted-p value < 0.05); gray dots indicate insignificant DEGs (adjusted-p value > 0.05). (c) Venn diagram of identified DEGs that are identical or specific between chicks and chick embryos with MG infection.
