Figure 7

C'-ADE by heterologous sera. Early viruses and sequential serum sets from 3 patients were tested against each other to investigate heterologous C'-ADE. The patient from whom the virus was derived is indicated on the far left, and serum at the top. White squares represent assays conducted in the presence of HIC'; grey squares, C'. The horizontal dashed blue line indicates the cut-off point for positive C'-ADE. Note that the scales of the Y-axes differ between subjects. Error bars represent standard deviations from 3 experiments.
