An enzyme-linked immunosorbent assay for the detection of human antibodies to Chlamydiae is described which exploits the cross-react properties between the genus-specific antigen of Chlamydiae and the ReLPS constituent of the outer membrane of a Salmonella minnesota mutant. Of 100 random sera tested by ELISA-ReLPS and immunofluorescence 78% showed an absolute correlation, 15% were positive in immunofluorescence and negative in ELISA and 7% were positive in ELISA and negative in immunofluorescence. Furthermore results obtained by the ELISA-ReLPS on 55 sera from patients with clinical evidence of Chlamydiae infection correlated well with the values obtained by an ELISA using Chlamydia-coated microtitration plates and by two immunofluorescence tests using Chlamydia trachomatis and Chlamydia psittaci as antigens. The method described here is sensitive, simple, reproducible and may be employed for epidemiological and pathogenetic studies of chlamydial infections.

UI MeSH Term Description Entries
D002689 Chlamydia A genus of the family CHLAMYDIACEAE whose species cause a variety of diseases in vertebrates including humans, mice, and swine. Chlamydia species are gram-negative and produce glycogen. The type species is CHLAMYDIA TRACHOMATIS.
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005455 Fluorescent Antibody Technique Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
