Abstract
A total of 573 patients hospitalized in National Seoul Mental Hospital and 76 of healthy persons as control were examined by indirect latex agglutination test in order to evaluate Toxoplasma antibody titers in mental patients. Throughout this survey, 1:32 or more titers of diluted sera were regarded as positive.
1. The 573 samples of test sera showed negative in 386 cases (67.4%), 1:2 in 93 cases (16.2%), 1:4 in 57 cases (9.9%), 1:8 in 14 cases (2.4%), 1:16 in 12 cases (2.1%), 1:32 in 5 cases (0.9%), 1:64 in 1 case (0.2%), 1:128 in 3 cases (0.5%) and 1:256 in 2 cases (0.3%) respectively.
2. Among total 573 mental patients, 11 cases (19%) showed positive, and they were 9 cases (1.8%) of schizophrenia and 2 cases (7.4%) of manic depression.
One case (1.3%) out of 76 control sera showed positive result.
