OBJECTIVES IgM antibodies are usually the first to be produced during treponemal infection. Three commercially available enzyme immunoassays (EIA) for detection of IgM antibodies against Treponema pallidum were evaluated. METHODS Results of the Anti-Treponema-pallidum-ELISA (IgM; Euroimmun), Pathozyme Syphilis M Capture (Omega Diagnostics) and recomWell Treponema IgM (Mikrogen) were compared ...
OBJECTIVE To determine the frequency of syphilis in female sex workers (FSWs) at red light area of Hyderabad. METHODS This study was conducted on female sex workers at red light area of Hyderabad, Pakistan during 2003. All female subjects who were between 17-35 years of age were evaluated and enrolled in the study. All such subjects were screened. for Treponema pallidum infection/syphilis by ...
It has been shown by our experiments that the serum of rabbits treated with emulsions of Treponema pallidum contains agglutinating substances. Normal rabbit serum also possesses agglutinating power for this organism, but, as in the case of normal bacterial agglutinins, to an extent very much inferior to that possessed by the sera of immunized animals. Normal human sera will agglutinate similar ...
Outbred Hartley male guinea pigs (300-400 g) were infected intradermally with various concentrations of Treponema pallidum Nichols strain in the pubic region. The median lethal dose (ID50) was approximately 10(5). The animals produced lesions visible by darkfield microscopy, treponemal antibodies (IgG only), and histopathological changes in the lymphoid organs. Though less susceptible to T pall...
Introduction Syphilis is a sexually transmitted infection. The infectious organism is a spirochete bacterium called Treponema pallidum subspecies pallidum. This organism also may transmit vertically inutero from mother to fetus resulting in congenital syphilis. The following is a case report of tertiary syphilis in the form of tabes dorsalis. This case is of interest due to the rarity of late n...
Reduced-minus-oxidized difference spectra of sonically treated virulent Treponema pallidum disclosed cytochromes of the b anc c types as well as large amounts of flavoprotein. Difference spectra of the carbon monoxide-binding pigment identified cytochrome o as the terminal oxidase. Physiological reduction of the cytochromes indicated that the cytochrome system was functional and established the...
