An indirect immunoferritin (IIF) technique is described for recognizing the elementary bodies (EB) of Chlamydia trachomatis in unsectioned preparations. Both the EB of a genital strain of C. trachomatis grown in irradiated McCoy cells and EB in clinical specimens obtained from patients attending a venereal disease clinic were identified by the IIF test in the electron microscope. Cell culture-grown EB were detected by ferritin staining for up to 4 weeks after the organisms had lost their infectivity for tissue cultures. The IIF test was of comparable sensitivity to isolation methods in detecting chlamydiae in clinical specimens. Other possible applications of the IIF technique are discussed.
本文描述了一种间接免疫铁蛋白(IIF)技术,用于在未切片的制剂中识别沙眼衣原体的原体(EB)。通过电子显微镜下的IIF试验,鉴定了在经辐照的McCoy细胞中生长的沙眼衣原体生殖道菌株的EB以及从性病门诊患者获得的临床标本中的EB。在细胞培养物中生长的EB在对组织培养物失去感染性后,通过铁蛋白染色可检测长达4周。在检测临床标本中的衣原体时,IIF试验与分离方法具有相当的敏感性。还讨论了IIF技术的其他可能应用。
