Seasonal Level of Hemoagglutinin Inhibiting and Its 2-Mercaptoethanol Sensitive Antibody in the Sera of Swine and Inhabitants

Seroepizootiology of Bovine Japanese Encephalitis in Two Prefectures

“…Since fattened pigs are usually shipped and sacrificed at 6 months of age, they are not useful for long-term seroepizootologic studies on JEV infection. In contrast, bovine species, which are reared for a much long- In pigs, 2ME sensitive IgM antibody was reported to appear in a primary JEV infection (Ogata, et al, 1985)5), and Ootsuka et al (1966)6) observed that 2ME sensitive JEV antibody increased in titers for 3-4 weeks after the primary infection, and later replaced 2ME resistence antibody. The same authors (1969)7) reported in bovine species that 2ME sensitive antibody was increased in titers in during early summer.…”
