1. One window-period donation in two years of individual donor-nucleic acid test screening for hepatitis B, hepatitis C and human immunodeficiency virus
Objective: To describe general data on nucleic acid/serology testing and report the first hepatitis B-nucleic acid testing yield case of an immunized donor in Brazil. Methods: A total of 24,441 donations collected in 2010 and 2011 were submitted to

2. Prevalência de sífilis em pacientes com HIV/AIDS atendidos em serviço de atendimento especializado em Vitória, ES.
Backgraound: Syphilis increases the risk of transmitting or contracting HIV and may have change its course in the patients. Reported cases of syphilis among patients living with HIV/AIDS has increased in the last decade, especially among men who have sex with men. Objectives: To determine the prevalence of and factors associated with syphilis infection in HI

3. Assessment of a Treponemal Competitive Enzyme Immunoassay for Syphilis Antibody Screening in 23,531 Serum Samples from a Low Prevalence Population. / Avaliação do uso de teste treponêmico imunoenzimático competitivo na triagem sorológica da sífilis em 23.531 soros de uma população de baixa prevalência
Foram testadas, com o teste não treponêmico VDRL e com o teste treponêmico imunoenzimático de competição, 23.531 amostras de soros, coletados em todas as regiões do Brasil, com o objetivo de verificar o comportamento do teste imunoenzimático treponêmico na triagem de amostras. A prevalência obtida foi de 0,63% com o VDRL e de 0,84% para o teste imu

4. Syphilis serology in patients with primary syphilis and non-treponemal sexually transmitted diseases in southern Africa.
The reactivity of a non-specific reagin (RPR) test and a specific treponemal (FTA-ABS) test were determined in 21 patients with primary syphilis, 430 patients with proven non-treponemal genital ulcerations and 719 patients with acute urethritis presenting at a clinic for sexually transmitted diseases in southern Africa. Excluding those 21 cases of primary sy

5. Influence of genital herpes on results of fluorescent treponemal antibody absorption test.
Both the fluorescent treponemal antibody absorption (FTS-ABS) test and Venereal Disease Laboratory (VDRL) test for syphilis were performed routinely on 113 men with histories of genital ulcerations. The difference in negative VDRL and borderline FTS-ABS results between patients with and without herpes simplex virus in their genital ulcers and no evidence of

6. Non-specific positive test results to syphilis in dermatological diseases.
Sera from 3028 patients attending a dermatological clinic were examined by the fluorescent treponemal antibody (FTA) test, the fluorescent antibody-absorbed (FTA-ABS) test, the Venereal Disease Research Laboratory (VDRL) test, and Kolmer's test. Eleven cases of late syphilis were found. Sera from 63 (2.08%) of the remaining 3017 patients showed non-specific

7. Anti-Teichoic Acid Antibodies and Non-treponemal Serological Tests for Syphilis
Antibodies specific for the polyglycerophosphate “backbone” of glycerol teichoic acids act as reagin in the Kolmer complement fixation test for syphilis.

8. Specificity of the Treponema pallidum haemagglutination test. Analysis of results.
The automated haemagglutination assay using Treponema pallidum antigen (AMHA-TP) and the Venereal Disease Research Laboratory (VDRL) test were used to examine 330 163 sera. Reactive results were checked by the fluorescent treponemal antibody-absorption (FTA-ABS) test. When isolated reactivity or non-reactivity in the AMHA-TP test was investigated an estimate

9. The Treponema pallidum haemagglutination (TPHA) test in biological false positive and leprosy sera
The Treponema pallidum haemagglutination (TPHA) test was carried out on 274 sera known to show biological false positive reactions to reagin tests for syphilis. The Treponema pallidum immunization (TPI) and fluorescent treponemal antibody absorption (FTA-ABS) tests were non-reactive on all these sera. Thirty-one or 11·3% showed reactive results in the TPHA

10. Development and evaluation of a monoclonal antibody inhibition enzyme linked immunosorbent assay to diagnose syphilis.
A highly specific inhibition enzyme linked immunosorbent assay (ELISA) using murine monoclonal antibodies to treponemes has been developed to diagnose syphilis. The monoclonal antibodies used in this study were reactive to antigens of both Treponema pallidum and Treponema pertenue and not to antigens of non-pathogenic treponemes. Inhibition of the binding of

11. Experimental infection of inbred guinea pigs with Treponema pallidum: development of lesions and formation of antibodies.
Inbred strain 2 and strain 13 guinea pigs were infected intradermally in the hind legs with different numbers of the virulent Nichols strain of Treponema pallidum. About 91% of the animals developed clearly visible lesions after being injected with 5 X 10(6) to 10 X 10(6) treponemes. T pallidum organisms could be isolated from skin lesions at various stages

12. Study of FTA-CFS test using monospecific anti-immunoglobulin conjugates IgG, IgM, and IgA *
The fluorescent treponemal antibody test for cerebrospinal fluid (FTA-CSF) using monospecific conjugates anti-IgG, IgM, and IgA was used to determine the presence of anti-treponemal antibodies in the spinal fluid of 335 patients with primary, secondary, and latent syphilis and symptomatic and asymptomatic neurosyphilis and of patients with certain neurologic
