Figure 2
The pattern of HEV viremia (A) and anti-HEV antibody (total Ig) development for contact-infected pigs and iv inoculated pigs (B). The first HEV-positive faecal sample is taken as starting point of the patterns (i.e. sampling 1) and two samplings represent 7 days. Ct and sample to cut-off ratios were averaged for contact-infected or iv inoculated pigs per sampling. Note that a lower Ct usually indicates a higher HEV-concentration and Ct >40 were set at 45. Error bars indicate the standard error of the mean; absence of error bars indicates that only one value was available for that time-point. As only four contact-infected pigs in Block 2 showed viremia with scattered times of onset, no graph could be produced for these pigs.
