Human Toxoplasma gondii-specific secretory immunoglobulin A reduces T. gondii infection of enterocytes in vitro.

Whey from 17 women (four acutely infected with Toxoplasma gondii, eight chronically infected, and five uninfected) was studied. T. gondii-specific secretory IgA antibodies were demonstrated by ELISA in whey from acutely infected and one of eight chronically infected women. Such antibodies to tachyzoite proteins of < or = 14, 22, 26-28, 30, 46, 60, 70-80, and > 100 kD (eliminated by protease but...

Tear and serum antibody levels in ocular herpetic infection: diagnostic precision of secretory IgA.

A sensitive enzyme linked immunosorbent assay (ELISA) was developed to evaluate the potential of herpes simplex virus (HSV) specific antibodies in the diagnosis of herpetic eye infection. The presence of HSV specific secretory IgA (sIgA) in tears was found to be diagnostic of infection. However, serum and tear HSV specific IgG and IgA were not considered reliable indicators of active infection.

استخراج آنتی ژن های دفعی- ترشحی انگل توکسوپلاسما گوندی در طراحی کیت الایزا اویدیتی (Elisa avidity)

Background and purpose: One of the transmission ways of the congenital toxoplasmosis is through the placenta to the fetus, therefore, its diagnosis at early stage is very important. Toxoplasma gondii parasite contains various antigens of which excretory-secretory antigens (E/SA) are used in designing Elisa avidity kit. The aim of this study was to compare the results of commercial kit and desig...

Lacrimal secretory IgA in active posterior uveitis induced by Toxoplasma gondii.

It is quite difficult to diagnose active toxoplasmosis in patients with ocular toxoplasmosis. Active posterior uveitis presumably due to Toxoplasma gondii infection (APUPT) is seldom produced during a prime-infection; hence most patients do not show high IgM antibodies. High levels of IgA have been described in active toxoplasmosis. The purpose of this study was to investigate possible associat...
