Serum samples from blood donors pregnant women in Khon Kaen were examined for antibodies to Toxoplasma by an indirect hemagglutination and indirect fluorescent antibody techniques. It was found that 6.4 per cent of the blood donors were positive by the indirect fluorescent antibody tests. The seroprevalence in pregnant women were 12.0 per cent by indirect hemagglutination and 4.7 per cent by indirect fluorescent antibody tests. The frequency distribution curves of indirect hemagglutination titers were unimodal in both groups studied. From the basis of these findings, it was concluded that toxoplasmosis is not endemic in Khon Kean and the transmission occurs at a very low level.
