Figure 5.
Transcript analysis of the 12 proteins differentially expressed in trachea (A) and kidney (B) of chickens infected with the IBV ck/CH/LDL/97I P5 and ck/CH/LDL/97I P115 strains by real-time RT-PCR. Total RNA extracts were prepared from the trachea and kidney of chickens in the control, P5-infected, and P115-infected group's at all four time points. Data represent means of three biological replicates per group. Error bars indicate standard error. Samples were normalized with the expression of the 18S ribosomal RNA gene. For symbols indicating different genes, refer to Tables 1, 2, 3, and 4.
