  1. a HI antibody titers were determined against A/chicken/Korea/ma163/04 (ma163/H9N2), A/aquatic bird/Korea/maW81/05 (maW81/H5N2), or A/Philippines/2/82 (Phil82/H3N2) viruses of the highest dilution of sera that inhibited hemagglutination by 4HA units of viruses. The results are the geometric mean titer of positive sera (≥20).
