    Abstract

    An enzyme linked fluorescence immunoassay (ELFA) has been evaluated for the detection of antibodies against Chlamydia trachomatis. Reticulate bodies and elementary bodies from C trachomatis L2/434 strain were used as antigens. An enzyme linked immunosorbent assay (ELISA) has also been evaluated using the same antigens. Results obtained by ELISA and ELFA for human sera with these two antigens were compared with each other and with the results obtained by a micro-immunofluorescence (micro-IF) test. Serum IgG antibodies against C trachomatis L2 reticulate bodies and elementary bodies were found in 32 (20.0%) and 11 (6.9%), respectively, of 160 serum samples from pregnant women by the micro-IF test (titre greater than or equal to 1/32). All of these 32 pregnant women had IgG antibodies to C trachomatis reticulate bodies (titre greater than or equal to 1/100), whereas 20 (12.5%) had IgG antibodies to elementary bodies in the ELISA. On the other hand, 25 (15.6%) and 19 (11.9%) of them had IgG antibodies to C trachomatis L2 reticulate bodies and elementary bodies, respectively, by the ELFA (titre greater than or equal to 1/500).
