Moreover, genes such as Ifr9, Ifr8, Ifr7, CSF2RA, STAT1, and STAT2 were expressed to a greater extent in the PmQ infection group than PmCQ2, and Il22, Il6, Nos2, Ccl4, Ccl5, Ifr1, Socs1, and Socs3 were increased only in PmQ infected chickens rather than PmCQ2. The gene discussed is CSF2RA; the disease is infection.
