Current syphilis tests cannot distinguish between active and past syphilis among patients with serofast rapid plasma reagin (RPR) titers. We investigated whether cytokine profiles might provide insight in the differentiation of active and treated syphilis.We collected quarterly serum samples from participants at risk for incident syphilis in a ...

Time series model based on global structure of complete genome [PDF]

, 2000
A time series model based on the global structure of the complete genome is proposed. Three kinds of length sequences of the complete genome are considered. The correlation dimensions and Hurst exponents of the length sequences are calculated.

Multiple Alleles ofTreponema pallidumRepeat Gene D inTreponema pallidumIsolates [PDF]

Journal of Bacteriology, 2000
ABSTRACTTwo newtprDalleles have been identified inTreponema pallidum:tprD2is found in 7 of 12T. pallidumsubsp.pallidumisolates and 7 of 8 non-pallidumisolates, andtprD3is found in oneT. pallidumsubsp.pertenueisolate. Antibodies against TprD2 are found in persons with syphilis, demonstrating thattprD2is expressed during infection.

Surface Mucopolysaccharides of Treponema pallidum [PDF]

Infection and Immunity, 1979
The viscous mucoid fluid that accumulates within syphilitic lesions may be due to breakdown of host tissue during infection, or may be synthesized by Treponema pallidum. Experiments were performed to investigate the acidic mucopolysaccharides that occur at the surface of T.
