✦ Synopsis

Of 160 sera collected from different age groups throughout Sweden, 38% were found to be antibody positive for group C rotavirus. The highest antibody prevalence rate was found in individuals aged 11-30 years (45%). An immunoprecipitation assay revealed that the antibodies were directed against VP2, VP4, VP6, VP7, and NSP2, with VP6 being the most immunogenic protein. Neutralising antibodies against a cultivable porcine group C rotavirus (strain AmC-1/ Cowden) were detected in 16/19 individuals at titres from 160 to 5,120. The results indicate that group C rotavirus infections are relatively common in older Swedish children and adults but appear to be less common in children younger than 5 years of age. It is concluded that porcine and human group C rotaviruses share epitopes critical for stimulation of neutralising antibodies.

To clarify the nature of serum anti-hypervariable region 1 (HVR1) antibodies in patients infected with hepatitis C virus (HCV), we assessed the reactivity of 21 patients' sera with 42 HVR1 proteins by Western blot. HVR1 was expressed as fusion proteins with glutathione S-transferase (GST). The patie
