background: toxoplasmosis is one of the prevalent parasitic diseases in the world with 10-40 percent of people having it as a latent infection. in cases of renal transplants, the condition either presents itself as a result of reactivation of the latent infection resulting in the weakness of immune system in a recipient or happens when a recipient simply contracts the condition from the donor t...

conclusions hemodialysis patients are high risk group for toxoplasmosis and should be tested periodically to prevent the dissemination of toxoplasmosis during dialysis. objectives the aim of this study was to determinate the anti- toxoplasma antibodies in hemodialysis patients of abadan and khoramshahr, southwest of iran. materials and methods sera of 150 patients (test group) aged 21 to 87 yea...

OBJECTIVES To determine the seroprevalence of Toxoplasma gondii (T. gondii), Rubella virus, and Cytomegalovirus (CMV) among pregnant women in Izmir, Turkey. METHODS Medical records of pregnant women attending Izmir Tepecik Training and Research Hospital, Izmir, Turkey between January 2014 and January 2016 were analyzed in this retrospective cross-sectional study. The 7513 T. gondii IgM/IgG re...

BACKGROUND Acute toxoplasmosis in pregnant women presents a high risk of Toxoplasma transmission to the fetus. Early diagnosis is difficult, especially when serological testing for IgG/IgM antibodies fail to differentiate between a recent and a past infection. In this case, we rely on IgG avidity or PCR assays. OBJECTIVES The aim of this study was to compare conventional ELISA and IgG avidity...

The BioPlex 2200 automated analyzer (Bio-Rad Laboratories, Hercules, CA) is a recently developed multiplex analyzer that enables the detection of anti-Toxoplasma, -rubella, and -cytomegalovirus antibodies in the same assay. The aim of this study was to compare this new technology (using the BioPlex 2200 ToRC IgG/IgM kit) in critical cases of serodiagnosis of toxoplasmosis (acute, chronic, or co...

To investigate the significance of the SARS-associated coronavirus (SARS-CoV) antibody, detected by ELISA and indirect immunofluorescence assays (IFA) for the SARS-CoV Vero E6 cell lysates, in non-SARS subjects, 114 serum samples from healthy controls and 104 serum specimens from autoimmune disease patients were collected. The results of ELISA showed that among 114 sera from healthy controls, 4...

We assessed the performance of the ARCHITECT Toxo IgG, IgM, and IgG Avidity assays against corresponding assays on AxSYM and Vidas using 730 sera from pregnant women. The ARCHITECT Toxo IgG and IgM assays showed a relative sensitivity of 97.5% and 89.9% and a relative specificity of 99.1% and 99.8%, respectively. If IgM sensitivity is calculated only for sera drawn less than 4 months after infe...

Development of heterogeneity of immunoglobulin classes has been investigated in the chicken by studying the effects of antibody-mediated suppression of IgM synthesis. Treatment of 13-day embryos with purified goat antibodies to IgM resulted in the elimination of IgM-containing cells from the bursa of Fabricius of 16- and 19-day embryos. When combined with bursectomy at hatching, administration ...

We have evaluated the diagnostic utility of eleven Toxoplasma gondii recombinant antigens (P22 [SAG2], P24 [GRA1], P25, P28 [GRA2], P29 [GRA7], P30 [SAG1], P35, P41 [GRA4], P54 [ROP2], P66 [ROP1], and P68) in immunoglobulin G (IgG) and IgM recombinant enzyme-linked immunosorbent assays (Rec-ELISAs). Following an initial evaluation, six recombinant antigens (P29, P30, P35, P54, P66, and P68) wer...
