Sera from 495 pregnant women were examined for toxoplasma antibodies by indirect fluorescent antibody testing (IFAT). Antibodies were positive in 32.7%. Seropositivity was not increased significantly with age but showed a statistically significant rise in accordance with frequency of parity, abortion and contact with cats. The high rate of seronegativity (67.3%) observed in pregnant women ...
Background and Purpose: According to the previous studies, Toxoplasma gondii excreted / secreted antigens (E/SA) appear to be suitable marker for serodiagnosis of toxoplasmosis. Most of the previous studies used whole E/SA. The present study, was carried out to evaluate the ELISA method using E/SA components from Toxoplasma gondii for the diagnosis of toxoplasmosis. Materials and Methods: ...
Background and purpose: Toxoplasmosis is a common zoonotic disease that is of particular importance in women before and during pregnancy. Therefore, this study aimed at investigating the seroepidemiology of Toxoplasma gondii in pregnant women and its risk factors in Golestan province, north of Iran. Materials and methods: A descriptive cross-sectional study was carried out in 440 blood samples...
New drugs are needed for treatment of Toxoplasma gondii infections. We tested derivatives of principles found in Isatis indigotica for in vitro efficacy against T. gondii infection. Indirubin-3'-oxime analogs showed modest micromolar activity, while tryptanthrin derivatives displayed 50% inhibitory doses in the low nanomolar range. Tryptanthrins have potential as anti-Toxoplasma infection thera...
A cross-sectional study was conducted to determine the seroepidemiology of Toxoplasma infection and its risk association among people having close contact with animals. A total of 312 blood samples were collected from veterinary personnel (veterinarian, technicians, and students) and pet owners from veterinary clinics and hospitals in the area of Klang Valley, Malaysia. About 4 cc of blood samp...
Background& Objective: Toxoplasmosis is a common infection among humans and animals. The disease is caused by Toxoplasma gondii. The prevalence of this infection depends on the weather conditions, dietary habits, and exposure to cats. This infection maylead to abortion, preterm labor and congenital anomalies in pregnant women. The present study is a descriptive cross – sectional study, whi...
background : schizophrenia is a serious, chronic, and often debilitating neuropsychiatric disorder. its causes are still poorly understood. besides genetic and non-genetic (environmental) factors are thought to be important as the cause of the structural and functional deficits that characterize schizophrenia. this study aimed to compare toxoplasma gondii infection between schizophrenia pat...
The main object of this paper is, by citing cases of laboratory infection with Toxoplasma, including one personal and hitherto unpublished, to point out the serious risks involved in working with this parasite and to stress the need for care. Another object is to see what can be learnt from these regrettable accidental human experiments about the signs and symptoms to be expected in toxoplasmosis.
The immune privileged nature of the CNS can make it vulnerable to chronic and latent infections. Little is known about the effects of lifelong brain infections, and thus inflammation, on the neurological health of the host. Toxoplasma gondii is a parasite that can infect any mammalian nucleated cell with average worldwide seroprevalence rates of 30%. Infection by Toxoplasma is characterized by ...
Background: If blood donors are infected with toxoplasmosis, they often have no obvious clinical symptoms due to a healthy immune system, but the Toxoplasma is still present in their white blood cells. Blood recipients are also often people with various anemia or defective immune systems. Therefore, receiving such blood will increase the risk of infection and acute form of toxoplasmosis. The ai...
