EFFECTS OF DIFFERENT FIXATIVES FOR TRICHOMONAS VAGINALIS IN INDIRECT FLUORESCENT ANTIBODY TEST

  • Online:1995-02-28 Published:2017-01-05

摘要: 在阴道毛滴虫IFA试验中,各种固定剂(福尔马林、甲醇、乙醇、丙酮)和自然干燥固定虫体时,荧光均明亮,抗体滴度相同,其中福尔马林、甲醇、乙醇固定的虫体鞭毛荧光清晰。甲醇和乙醇固定的虫体荧光特异,呈亮圈状。用阴道毛滴虫不同虫株、不同虫数制备抗原片和McAb(单克隆抗体)不同株进行IFA试验,荧光效果均有差异。虫数以1.2×106个/ml和2.4×105个/ml为佳。抗原片在4℃和-20℃冰箱内,抗原性可保存3个月。

Abstract: This paper dealed with the effects of different fixatives for Trichomonas vaginalis in indirect fluorescent antibody test. T.vaginalis fixed by formalin,methanol or alcohol displayed clear flagellae.The parasites fixed by methanol and alcohol showed specific ring like fluorescence with 1 2 bright dots. Antigen slides prepared from different Trichomonas strains,different number of parasites and anti Trichomonas vaginalis McAb strains in IFA presented different results.Antigen slides showed the best results when using parasites at concentrations of 1.2×10 6 cells/ml or 2.4×10 5 cells/ml. Antigen preparations stored at 4℃ or -20℃ remained reactive throughout the experimental period of three months.
