Properties
Background Treponema pallidum subsp. pallidum is the causative agent of Syphilis, a chronic disease occuring only in humans. The disease progresses through stages. After a short propagation period at the site of infection (primary stage) the hematogenic spreading of the pathogen throughout the entire organism follows (secondary stage). After the decline of acute symptoms Treponema pallidum can persist for years or lifetime in the human organism (stage of latency) and then can cause late complications (tertiary Syphilis). During pregnancy the pathogen can be transmitted to the fetus (Syphilis connata). In approximately 40 % of the cases infection results in abortion or death of the child shortly after birth. The propability of infection in utero is around 40-70 %.The serodiagnosis of syphilis is performed in steps. As a rule, the T. pallidum hemagglutination assay (TPHA) is used as an antibody screening test. As modern screening test system, the recomWell Treponema IgG, IgM is an excellent alternative. The main advantages of the recomWell Treponema tests are the possibility to distinguish between IgG and IgM antibodies and the capacity to process large numbers of samples accompanied by an automated readout. In addition, by the use of purified, recombinant antigens, the recomWell Treponema tests offer a reproducible higher specificity with maximum sensitivity.

Description Test principle and procedure.

Indirect sandwich test. Recombinant antigens are bound to the solid phase.

1. 1st Incubation
2. Add patient samples diluted 1:101 (sample: 10 µl of serum or plasma), incubate for 1 h at 37 °C.
3. Wash 4 times
4. 2nd Incubation
5. Add peroxidase conjugated anti-human IgG or IgM antibodies (conjugate), incubate for 30 min at 37 °C.
6. Wash 4 times
7. Color reaction. Add ready-to-use TMB solution and incubate for 30 min at room temperature. Stop the substrate reaction with H3PO4 and measure the extinction at 450 nm.
