The clinical outcomes of single infections and coinfections with PEDV and CPA in weaned piglets. (A) The clinical significance scores (CSS) for each group. The CSS of individual pigs from each group was measured as described in Materials and methods. (B) The fecal viral RNA shedding profile of PEDV in each group. The PEDV RNA titers (log10 genomic copies/ml) in rectal swaps at the indicated sampling time points were determined using rRT-PCR. The mean values for each group at each time point are presented, and error bars indicate the SDM. The P-values were calculated by comparing the data between the PEDV/CPA coinfection and single-infection groups. *, P = 0.001–0.05; **, P < 0.001
