应用微量间接血凝法（IHA），对289例高原地区（海拔2260米）病理妊娠和正常妊娠孕产妇血清中弓形体抗体进行了检测与分析。结果表明：藏族理妊娠孕产妇血清的弓形体抗体阳性率较高（10.16％），但在藏、回、土、汉四民族间病理妊娠弓形体抗体阳性率差别无统计学意义（X2=0.3295，P＞0.05）；农民病理妊娠孕产妇血清的弓形体抗体阳性明显高于干部、工人及其它职业者，其差别有统计学意义（X2=9.47，P＜0.05）。提示高原地区孕产妇弓形体感染的民族和职业分布较广，应加强产前检查和及时治疗，以达到优生的目的。
By using the indirect hemagglutination assay (IHA), toxoplasma gondii antibody was detected and analyzed in 289 cases of high altitude (2260 meters above sea level) pathological pregnancy and normal pregnant maternal serum. The results showed that the positive rate of Toxoplasma antibody in pregnant pregnant and maternal serum was higher (10.16%), but there was no significant difference in the positive rate of Toxoplasma antibodies between Tibetan, Hui, Tu, and Han ethnic groups (X2=0.3295). (P>0.05); Farmers pathological pregnancy maternal serum toxoplasma antibody positive was significantly higher than the cadres, workers and other professionals, the difference was statistically significant (X2 = 9.47, P <0.05). It is suggested that the ethnic and occupational distribution of pregnant women with toxoplasma in the plateau region should be widely distributed. Prenatal examination and timely treatment should be strengthened to achieve the goal of eugenics.
