Antibodies against Chlamydia trachomatis
Indications: Test system for the in vitro determination of antibodies against Chlamydia trachomatis in human serum or plasma for the diagnosis of the following diseases: trachoma,
urogenital tract infections and lymphogranuloma venereum.
Clinical significance: The infectious agent Chlamydia trachomatis belongs to the human pathogenic Chlamydia genus, together with Chlamydia pneumoniae and Chlamydia psittaci. It is one
of the smallest intracellular gram-negative bacteria. Around 700 million people are infected
worldwide, with an annual new infection rate of around 50 million. The disease is transmitted
by contact with infected humans.
C. trachomatis is the agent of non-gonorrheal urethritis, lymphogranuloma venereum, trachoma, inclusion conjunctivitis, neonatal pneumonia and Reiter’s syndrome. Sexually transmitted
non-gonorrheal urethritis is the most frequent venereal disease. In Germany the C. trachomatis
serotypes D to K are responsible. They cause urethritis, epididymitis and prostatitis in men, and
urethritis, cervicitis and salpingitis/adnexitis in women. Lymphogranuloma venereum is caused
by the Chlamydia trachomatis serotypes L1 to L3. It is a rare venereal disease which occurs
worldwide but mainly in tropical areas. In tropical regions, C. trachomatis leads to trachoma
(with serotypes A, B, Ba and C), an eye infection of varying severity. It is caused by direct contact with the mucous membranes of the eye, nose and mouth and can be transmitted by common use of hand towels. Around 400 million people suffer from trachoma, which is worldwide
the most frequent cause of blindness (trachoma blindness). In newborns, particularly premature
infants, prenatally or perinatally transmitted C. trachomatis causes pneumonia (serotypes D to
K) in addition to conjunctivitis (ophthalmia neonatorum). This is noticeably often accompanied
by pneumothorax and lifelong health problems.
Despite distinct clinical symptoms, C. trachomatis antibodies are not necessarily produced in
the serum in localised processes. IgM antibodies are not formed in all cases of florid infection.
An increase in IgG titer is also not always found. In problem cases, it is therefore useful to
determine the presence of Chlamydia in infectious secretions using direct immunofluorescence
or to determine their specific genetic sequences using PCR, which is often unsuccessful in cases
where the infection has taken place some time ago. The fastest and most reliable investigation of specific antibodies in infections with C. trachomatis, even with low antibody titers, is
obtained with MIF (microimmunofluorescence) as “gold standard“, IIFT (indirect immunofluorescence test) and ELISA (enzyme linked immunosorbent assay) using MOMP as the target
antigen and taking into consideration different serotypes. Studies throughout Europe show that
these methods are suited to confirming C. trachomatis-induced infertility in women and men by
the determination of C. trachomatis specific serum IgA and IgG antibodies. Recognised medical
centres therefore recommend C. trachomatis screening for both parents before pregnancy.
Fluorescence pattern (positive reaction): Antibodies against Chlamydia trachomatis cause a
fluorescence of the inclusion bodies located in the cytoplasm. These inclusion particles contain
densely organised elementary bodies (infectious form of Chlamydia, diameter 300 nm) and
reticular bodies (non-infectious form of Chlamydia, diameter 1000 nm). Free elementary and
reticular bodies lying between the cells can also react. Some of the cells in the field of view are
not infected and show no fluorescence.

Test principle: The indirect immunofluorescence test is a
standardized in vitro assay for the determination of specific
antibodies against C. trachomatis. BIOCHIPs are coated with
C. trachomatis infected cells and fixed onto the reaction
fields of a microscope slide. With EUROIMMUN BIOCHIP
Mosaics®, different substrates can be positioned next to each
other in one reaction field and incubated with one drop of
diluted serum, allowing a detailed patient antibody profile to
be established with a single test.
Test procedure: EUROIMMUN BIOCHIP slides are incubated
using the proprietary TITERPLANE™ Technique, which enables multiple samples to be incubated next to each other
and simultaneously under identical conditions. Results are
evaluated by fluorescence microscopy. Incubation of the
substrate with the positive and negative control sera provided in each kit verifies correct performance of the test and
aids evaluation.
