Pathology scoring in lung liver and kidney of SEOV infected rats. A comparison of histological scoring of samples stained with haematoxylin & eosin (HE) was performed between adult animals that were seropositive (SEOV +) and juvenile animals that were seronegative (SEOV −; (A)), or in adult animals that were positive (PCR +) or negative (PCR−; (B)) for viral RNA in liver or kidney. Bars present the average score between animals. The error bars represent the standard deviation of the mean (* = p < 0.05, Student’s t-test).
