Toxoplasma gondii
In an experiment, serum samples taken from toque macaque individuals at Polonnaruwa were examined for antibodies to "Toxoplasma gondii" by the modified agglutination test. There was no evidence of maternal transmission of antibodies or congenital toxoplasmosis. None of the infected macaques died within 1 year after sampling. "Toxoplasma gondii" infection was closely linked to human environments where domestic cats were common. Although infection with "T. gondii" has been noted in several species of Asian primates, this is the first report of "T. gondii" antibodies in toque macaques.
