71793-4Treponema pallidum Ab [Titer] in Serum or Plasma by AgglutinationActive

Term Description

Identification of Treponema pallidum antibodies by particle agglutination is performed for the diagnosis of syphilis caused by T. pallidum. This code was created for a test that uses the same treponemal antigen as hemagglutination tests (MHA-TP) but with gelatin particles, allowing for testing with serum or plasma samples.

Part Description

LP14042-3   Treponema pallidum
Treponema pallidum is a spirochaete bacterium. Pathogenic treponemes are classified based upon their clinical manifestations in humans: venereal syphilis, yaws, endemic syphilis and pinta. Nonpathogenic treponemes are often part of the normal flora of the genital tract, oral cavity or intestinal tract. Treponemal infections exhibit diverse clinical manifestations which are characterized by distinct clinical stages. Multiplication of the bacterium at the entry point causes the primary stage. Dissemination of treponemes to other tissues produces the second stage. After a latency period (up to 20 to 30 years), the tertiary stage develops. T. palladum subsp pallidum (venereal syphilis) is the most destructive subspecies and produces lesions in many bodily tissues including the central nervous system. Congenital syphilis may result in birth defects or fetal death. Venereal syphilis is sexually acquired except for congenital syphilis, which is transmitted to the fetus during the later stages of pregnancy. The other treponemes are acquired by close nonvenereal contact. Control of both venereal and nonvenereal disease is based upon surveillance and antibiotic treatment of contacts.
