Flourescent antibody test (FAT) was applied to determine the cross-reactivities of monoclonal (mAb), polyclonal (pAb) antibodies to Neospora, Toxoplasma and Cryptosporidium and antisera from cattle naturally infected with Neospora canium against antigens from a number of sources. Both mAb and pAb to Neospora reacted strongly (FAT titre up to 2560) with the homologous antigens and demonstrated w...

Results The study included 30 patients, with HIV infection, 26 (86.7%) of them with antiretroviral treatment, while 4 (13.3%) of them without treatment. Two patients (6.66%) without antiretroviral treatment were found with protective antibody for Toxoplasma gondii, while 8 (26.66%) patients with antiretroviral treatment were found with the same antibodies. Two cases from the last category (6.66...

We determined the prevalence of Toxoplasma antibodies in 576 primigravid women randomly selected from health houses in Hamadan. The relationship between positivity and some risk factors was assessed. Data were collected by questionnaire and blood samples examined for Toxoplasma antibodies by indirect fluorescent antibody test. Of the 576 women, 193 (33.5%) were positive for Toxoplasma antibodie...

Introduction: Acute Toxoplasmosis is more critical in immunocompromised patients with cancer. The present study was conducted to investigate the anti-Toxoplasma gondi antibodies and assess the toxoplasmosis risk in women with breast masses in western of Iran in 2012. This research was done as a case-control study on women who referred to the treatment centers in cities of Kermanshah and Ilam ...

The inner membrane complex (IMC) of Toxoplasma gondii as a peripheral membrane system has unique and critical roles in parasite replication, motility and invasion. Disruption of IMC sub-compartment protein produces a severe defect in T. gondii endodyogeny, the form of internal cell budding. In this study, we generated T. gondii virus-like particle particles (VLPs) containing proteins derived fr...

OBJECTIVE Epilepsy is a disorder of the brain characterized by an enduring predisposition to generate seizures. Infectious agents are mentioned in its etiology. With identifying and appropriate treatment of these infectious agents, preventing their secondary outcomes, including seizure is possible. This study was conducted to determine frequency of anti-Toxoplasma antibodies (IgG, IgM) and anti...

toxoplasma gondii has arisen as an important opportunistic agent especially in the central nervous system and in advanced hiv disease can cause significant morbidity and mortality. this study was carried out to determine the seroprevalence of toxoplasmosis among hiv-positive patients in iran. blood samples were collected from 201 hiv-positive patients and anti-toxoplasma antibodies were detecte...

The analysis of 4450 toxoplasma serology results showed that 59 (1.3%) latex agglutination reactions were not confirmed in the dye test. These discrepant results were associated with an unspecified IgM antibody but not associated with kit batch variation, inactivation of sera, concurrent cytomegalovirus infection, or the presence of hepatitis B virus "e" antigen. The latex agglutination test is...
