Expression Pattern of Genes of RLR-Mediated Antiviral Pathway in Different-Breed Chicken Response to Marek’s Disease Virus Infection

Figure 2

MDV genome load in spleen of broilers and Erlang mountainous chickens following infection with MDV. The groups were as follows: Broiler-MDV = chickens from the broilers infected with MDV, EM chicken-MDV=chickens from Erlang mountainous chickens infected with MDV. MDV infected group was infected with virulent strain of MDV. At 4, 7, and 21 d.p.i, six broilers and eight Erlang mountainous chickens of infected group were killed. The MDV genome loads in spleen of killed chickens were analyzed by real-time PCR. A: significant compared to broiler-MDV observed at 4 d.p.i. B: and C: significant compared to broiler-MDV and EM chicken-MDV observed at 4 d.p.i, respectively. D: significant compared to broiler-MDV observed at 7 d.p.i. E: significant compared to broiler-MDV observed at 21 d.p.i. Error bars represent standard error of the mean.
