应用斑点酶联免疫吸附试验 (Dot -ELISA)对 916份孕妇血清及 50 0份健康献血者血清作了弓形虫抗体的检测 ,阳性率分别为 5 6 8% (52 / 916 )及 6 4 0 % (32 / 50 0 ) ;采用纤维支气管刷检物姬氏染色检查 2 85例肺部疾病患者 ,共查到 7例卡氏肺孢子虫包囊阳性者 ,阳性率为 2 4 6 % (7/2 85) ;应用改良抗酸染色法及碘液染色法分别对 150例腹泻患者及 12 4 0例健康者进行检查 ,腹泻患者的隐孢子虫感染率为 0 6 7% (1/ 150 ) ,健康人群兰氏贾第鞭毛虫的感染率为 3 0 6 % (38/12 4 0 )。
Dot-ELISA was used to detect Toxoplasma gondii antibody in 916 pregnant women and 50 healthy blood donors. The positive rates were 5 6 8% (52 / 916) and 6 4 0 respectively. % (32/50 0 ); Fibrobronchial brushing test was used to detect 285 patients with lung diseases. A total of 7 cases of Pneumocystis carinii cyst positive were found, with a positive rate of 24% (7 /2 85) ; Using modified acid-fast staining and iodine staining, 150 patients with diarrhea and 120 healthy persons were examined. The infection rate of cryptosporidium in patients with diarrhea was 0.67% (1/150). The infection rate of Giardia lamblia was 306% (38/1240) in healthy people.
