Abstract
From February to March 1999, a seroepidemiological survey on Japanese encephalitis virus (JEV) was carried out. One thousand and thirteen serum samples of swine were collected from 37 farms in 4 provinces at the southern border of Thailand; Songkhla, Yala, Narathiwat and Satun. Japanese encephalitis virus antibody was measured using microtiter hemagglutination inhibition (HI) test. The results indicated that 95.12 - 99.42% of the breeder pigs had JE-HI antibodies at ≥ 1:40 compared with 89.08% of the gilts. The percentages of seropositive animals were 49.75%, 50.65% and 100% in fattening pigs, weaning and suckling piglets, respectively. The study demonstrated a high exposure rate of JEV infection among swine population raised on the southern border of Thailand.
