direct agglutination test (dat) is a sensitive and simple method, which is applicable in field and unequipped laboratories. in order to evaluate dat in the diagnosis of toxoplasma infections, the antigen was prepared in the protozoology unit, school of public health and it was used in the following studies. a- 251 serum samples collected from suspected toxoplasmosis out-patients were examined f...

An immunoglobulin M (IgM)-immunosorbent agglutination assay (IgM-IS-AGA) was negative in all sera from individuals negative in the Sabin-Feldman dye test, in sera from individuals with chronic Toxoplasma infection, and in cord blood samples from uninfected infants. In contrast, all sera that were obtained from individuals with a recent history of acute Toxoplasma infection and from infants with...

Toxoplasma gondii is a protozoan parasite that widely distributed in the human population and responsible for corresponding global morbidity. Specifically, T. causes toxoplasmosis, leading to miscarriage, stillbirth, neural disorders. This attacks different organs glands, such as thyroid gland, various health issues. Recently, studies have established link between autoimmune diseases (AITD), wh...

Infection with Toxoplasma gondii is often asymptomatic and, when acquired during pregnancy, may lead to connatal toxoplasmosis in the offspring. The newly introduced Vitros anti-Toxoplasma immunoglobulin G (IgG) and IgM assays, designed for the Vitros ECiQ immunodiagnostic system, a fully automated system based on chemiluminescence, were evaluated as a screening method for the serological detec...

conclusions based on the findings of the present study, the frequency of toxoplasma infection is high in the studied population, although it is fairly close to the findings of reports from the other areas of iran. results in total, 1910 (29.87%) out of 6393 subjects were found to be infected with toxoplasma gondii. in terms of the seropositivity, 1871 (32.42%) out of 5770 and 128 (2.14%) out of...

High antibody titres to Toxoplasma gondii and Chlamydophila psittaci were demonstrated in serum collected from domestic pigeons at average titres of 1:128 and 1:64 respectively. The public health implications of these findings are discussed.

  Background and Objectives: Toxoplasmosis has become one of the more frequent opportunistic infections and the most common cause of focal brain lesions complicating the course of AIDS. However, there is a little information about the frequency of the toxoplasmosis in various regions of Iran. At the present study, we evaluated the prevalence of toxoplasmosis in patients with AIDS in Mashhasd (...
