title: Serologic prevalence of Toxoplasma gondii in field mice, Microtus fortis, from Yuanjiang, Hunan Province, People's Republic of China.
abstract: Antibodies to Toxoplasma gondii were investigated in serum samples of field mice, Microtus fortis, from Yuanjiang, Hunan Province, People's Republic of China. The modified agglutination test (MAT) incorporating formalin-fixed whole tachyzoites and mercaptoethanol was used to determine antibodies. Antibodies to T. gondii (MAT > or = 1:20) were found in 36 (29%) of 124 trapped mice. The antibody titers of positive sera (percentage in parentheses) were 1:20 (8.9), 1:40 (3.2), 1:80 (3.2), 1:160 (1.6), 1:320 (1.6), 1:640 (1.6), 1:1,280 (1.6), 1: 2,560 (0.8), and > 1:2,560 (6.5). No antibody to T. gondii was found in 104 sera of laboratory-bred M. fortis infected with Schistosoma japonicum between 1 and 45 days after infection.
