introduction : toxoplasmosis, caused by toxoplasma gondii, is a protozoan parasitic infection distributed worldwide. early infection by this protozoa can lead to abortion and congenital toxoplasmosis in pregnant women. this study was conducted to determine the seroprevalence of t. gondii infection among pregnant women referring to shahid akbar abadi hospital, tehran, iran during 2010-2013. meth...

background: toxoplasma gondii infects a wide range of animals; felines are definitive hosts and other animals including the dogs are intermediate hosts. the aim of this study was to determine the seroprevalence of t. gondii infection in dogs in tehran, capital of iran and to investigate possi­ble associated risk factors. m ethods: three hundreds ninety six serum samples were collected during 20...

With the emergence of the human immunodeficiency virus (HIV), in patients with acquired immunodeficiency syndrome (AIDS), Toxoplasma gondii has arisen as an important opportunist pathogenic agent, especially in the central nervous system, being the most common cause of intracerebral lesions. The incidence of Toxoplasma gondii in HIV-infected patients depends principally on the existence of late...

BACKGROUND The diagnosis of reactive arthritis is a challenging clinical problem in daily practice. Although there are many triggering infectious agents for reactive arthritis, Toxoplasmosis, a worldwide parasitic infection has not been reported. AIM We investigated the serologic evidence of Toxoplasma gondii ( T. gondii ) infection in patients with newly diagnosed reactive arthritis after si...

objective: sera from 186 sheep (93 rams and 93ewes) from tabriz, north-west of iran were evaluated for antibodies to toxoplasma gondii using a commercial elisa kit. methods: the animals were divided into two age groups (< 2 years, and > 2 years). results: antibodies to t. gondii were found in 13 of 186 sheep (6.98%). infection rate in ewes was higher than rams but this difference was not signif...

The present study was performed to clarify whether structural proteins are constituants of the antigens of Toxoplasma gondii which circulate in the sera of experimentally infected mice. Rabbits were immunized with mice sera containing circulating antigen, the rabbit sera were then tested for antibodies against Toxoplasma gondii. Low titers of specific antibodies, directed against cell wall prot...

Multiplication of Toxoplasma gondii was examined in vitro in murine erythroid cells at different stages of development. Toxoplasma gondii multiplied in nucleated erythroblasts and enucleated reticulocytes from the foetal liver, and in immature reticulocytes and yolk-sac derived erythrocytes from the foetal circulation. However, the rate of multiplication was lowered as erythroblasts matured, an...

Toxoplasma gondii can infect all species of warm-blooded animals, including humans, and causes serious diseases in immunocompromized hosts. Live tachyzoites derived from serial passage in HeLa culture were used in the Sabin-Feldman dye test for detection of Toxoplasma gondii antibody in serum samples of 21 captive wild felids including one fishing cat (Prion nailurus viverrina), one leopard (Pa...

A survey was carried out to determine the prevalence of Toxoplasma gondii antibodies among cattle farmers and cattle in the Gombak District, Selangor. A total of 79 human and 73 cattle serum samples were tested for Toxoplasma gondii antibodies by the immunofluorescent technique (IFAT). Results of the survey showed that anti-Toxoplasma gondii antibodies were found in 27.8% of the farmers, while ...
