Abstract

Atayal aborigines, living at an altitude of 1, 500-1, 600 m in northeastern Taiwan, still hunt for wild animals with the help of hunting dogs. In this study, the latex agglutination test (LAT) was used to detect sera anti-toxoplasma antibodies in this community as a measure of their exposure to Toxoplasma gondii. The positive rates for sera anti-toxoplasma antibodies were 21.8 % and 19.6%, respectively, in 422 Atayal and 51 hunting dogs tested. Neither of the positive rates were found to be significantly different between male (22.1 %) and female A tayal (21.4%), or between humans (21.8%) and dogs (19.6%) (P>0.05) when compared by the Chi-Squared test (χ2-test) . A significant difference was observed between the positive rates in adults (28.3%) and children (18.7%) (P<0.05), and the age pattern of prevalence is consistent with an increasing duration of exposure to Toxoplasma gondii with age. The consumption of raw liver of wild animals or insufficiently cooked meat may be the major mode of transmission of toxoplasmosis in Atayal.
