The enzyme-linked immunosorbent assay (ELISA) technique, using an ultrasonicate of Treponema pallidum as antigen, has been evaluated as a serological test for syphilis. It is concluded that the test is simple, reliable, and relatively quick and that its sensitivity in all stages of syphilis is equal to the FTAABS test. Because its specificity is probably also high, ELISA might be used in future...
Infection with Borrelia burgdorferi, the etiologic agent of Lyme disease, is associated with an early and dominant humoral response to the spirochete's 23-kDa outer surface protein C (OspC). We have cloned and expressed OspC as a fusion protein in Escherichia coli and have shown that patient serum samples react with it in an enzyme-linked immunosorbent assay (ELISA) (S. J. Padula, A. Sampieri, ...
A new commercially available rapid screening immunochromatographic test (ICT) for Detection of anti-rubella IgG & IgM antibodies was compared with ELISA. Materials and methods: 161 serum samples were tested by immunochromatography card test (Rubella IgG/IgM, SD –Bioline) and were compared with a standard IgG & IgM ELISA (Ani Biotech Oy, Orgenium Laboratories, Vantaa, Finland). Results: ELISA an...
This work compared the time at which negative seroconversion was detected by conventional serology (CS) and by the ELISA-F29 test on a cohort of chronic chagasic patients treated with nifurtimox or benznidazole. A retrospective study was performed using preserved serum from 66 asymptomatic chagasic adults under clinical supervision, and bi-annual serological examinations over a mean follow-up o...
Two types of porcine reproductive and respiratory syndrome virus (PRRSV) have been reported, the European type (EU PRRSV) and the North American type (US PRRSV). We developed a dual enzyme-linked immunosorbent assay (ELISA) for the simultaneous detection and differentiation of serum antibodies directed against either of the two PRRSV types. This tandem PRRS ELISA is based on affinity-purified r...
Bovine Leukemia Virus (BLV) is the etiologic agent of Enzootic Bovine Leukosis, a retrovirus exogenous to the bovine species. Once infected, there is no detectable viraemia but instead there is a strong and persistent immunological response to BLV structural proteins, essentially the gp51 envelope glycoprotein and the mayor core protein p24. We describe the test procedure of an indirect ELISA (...
