Serologic Evidence of Frequent Human Infection with WU and KI Polyomaviruses
Figure 2. ELISA results from 3-year age group. A) 29 serum samples in the 3-year age group were assayed for antibodies against WU polyomavirus viral protein 1. B) KI polyomavirus ELISA results from the same 29 serum samples. The cutoff values for WU ELISA (0.713) and KI ELISA (0.572) are represented by dashed lines; –, negative control serum; +, positive control serum. Error bars indicate mean and SD.
