A simple, sensitive enzyme linked fluorescence immunoassay has been developed to detect IgM antibodies against Chlamydia trachomatis. Reticulate bodies and elementary bodies from C trachomatis L2/434 Bu strain were isolated and used as antigens in the assay. Of 113 serum samples obtained from infants with pneumonia, 27 (23.9%) had IgM antibodies to C trachomatis L2 reticulate bodies and nine (8.0%) had IgM antibodies to C trachomatis L2 elementary bodies (titre greater than or equal to 1/500). Specific IgM antibodies were not detected in 20 control serum samples obtained from healthy adults and children. The possible use of enzyme linked fluorescence assay to determine IgM antibodies in the serodiagnosis of C trachomatis infection is discussed.
已开发出一种简单、灵敏的酶联荧光免疫分析法来检测抗沙眼衣原体的IgM抗体。从沙眼衣原体L2/434 Bu菌株中分离出网状体和原体,并将其用作该分析中的抗原。在从肺炎婴儿中获得的113份血清样本中,27份(23.9%)有针对沙眼衣原体L2网状体的IgM抗体,9份(8.0%)有针对沙眼衣原体L2原体的IgM抗体(滴度大于或等于1/500)。在从健康成人和儿童中获得的20份对照血清样本中未检测到特异性IgM抗体。讨论了酶联荧光分析法在沙眼衣原体感染血清诊断中用于测定IgM抗体的可能性。
