Abstract

Serum specimens from children and adults living in Sapporo, Japan, were tested for antibody against human calicivirus by immune electron microscopy (IBM), using virusโ€rich faecal extracts as the source of antigen. Of 83 serum specimens tested, 49 (59%) were positive for calicivirus antibody. Ageโ€related prevalence of antibody to calicivirus was as follows: 23% (3/13) in the 0โ€“5โ€monthโ€old group, 30% (6/20) in the 6โ€“23โ€monthโ€old group, 65% (13/20) in the 2โ€“5โ€yearโ€old group, and 90% in school children (18/20) and adults (9/10). As for IBM antibody ratings scored from 0 to 4, almost all positive sera from older infants and preschool children scored 3 to 4. Antibody scores were rather more scattered in school children. The results indicated that caliciviral infection is prevalent in younger children in this part of Japan.
