Abstract: 1981年長崎県で採取されたブタとウシ血清のゲタウイルスに対するELISA抗体価を測定した.7月21日以前に屠殺場で採取されたブタ血清のIgG-ELISA抗体陽性率と抗体価の幾何平均値は低かったがその後速やかに各々80%と4倍以上に上昇した.一方,IgM抗体はウイルス血症と同じ日の7月7日に初めて検出された後陽性率は上昇し7月21日には60%に達した。日本脳炎ウイルスの分離と抗体保有率の経移と比較すると1981年長崎県のブタの間ではゲタウイルスが日本脳炎ウイルスよりも約4週間早くその感染が起こっていた事になる。ブタと比べてウシの抗体保有率は流行期末の9月でも27%と低値であった。 / Antibody titers against Getah virus were measured by the indirect ELISA using swine and bovine sera collected in Nagasaki Prefecture, Japan, in the year of 1981. IgG-ELISA antibody positive rate and its geometrical mean titer (GMT) in swine sera collected at a slaughter house were low until the 21st of July, and increased rapidly in the following week to 80% and 4-fold higher, respectively. Whereas, IgM antibody first became detectable on the 7th of July, coinciding to the Getah virus viremia, then, its positive rate increased to the level of 60% on the 21st of July. Compared with the result of Japanese encephalitis (JE) virus isolation and antibody appearance, circulation of Getah virus among swine population in Nagasaki Prefecture occurred 4 weeks before that of JE virus in 1981. In contrast to swine population, antibody prevalence among bovine was low (less than 27%) even at the end of the epidemic season in September.
