Seroprevalence of Toxoplasma gondii in Elephants (Elephus maximus indicus) in Thailand

Serum samples from captive 156 elephants (Elephus maximus indicus) from Thailand were examined for antibodies to Toxoplasma gondii using the modified agglutination test (MAT) and the latex agglutination test (LAT). Antibodies to T. gondii were found in 45.5% of 156 elephants by MAT (≥1:50) and 25.6% of 156 elephants by LAT (≥1:64). This is the first report of T. gondii infection in E. maximus indicus from Asia.
