Anterior uveitis in a kitten infected with Toxoplasma gondii (Tehran strain)
Ocular lesions are a common manifestation of toxoplasmosis in cats. In this survey, 10 healthy Syrianmice were infected through intraperitoneal inoculation of bradyzoites of Toxoplasma gondii (Tehran strain).Mice were killed 30 days after inoculation and the suspension of their brains was prepared, after confirmationof the infection. Seven kittens were fed with the infected mice brain suspensio...
متن کاملComparative proteomic analysis of virulent and avirulent strains of Toxoplasma gondii reveals strain-specific patterns
Research exploring the proteome of Toxoplasma gondii oocysts has gained momentum over the past few years. However, little is known about the oocyst's protein repertoires that contribute to differential virulence among T. gondii strains. Here, we used isobaric tag for relative and absolute quantitation-based proteomic analysis of oocysts of two T. gondii strains exhibiting the virulent PYS (Toxo...
متن کاملImmunogenicity of Gamma-Irradiated Toxoplasma gondii Tachyzoites in Mice
The Immunogenicity of γ-irradiated tachyzoites of a highly virulent strain of Toxoplasma gondii (RH strain) was investigated. Immunized mice survived challenge infection and displayed increased interferon gamma (INF-γ ) production. On the other hand, nonimmunized controls died after 10 days and displayed a significantly decreased lymphoproliferative response to Concanavalin A (Con A). No tachyz...
متن کاملSeroprevalence of Toxoplasma gondii Infection in Dogs in Tehran, Iran
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. METHODS Three hundreds ninety six serum samples were collected during 2007...
متن کاملbrain tissue cysts in infected mice with rh-strain of toxoplasma gondii and evaluation of bag1 and sag1 genes expression.
background : toxoplasma gondii is an obligate intracellular parasite that infects humans at high preva-lence rates. the virulent rh strain of t. gondii is generally considered to have lost its cyst forming ca-pacity. this study performed to obtain tissue cysts in mice infected with tachyzoites of rh strain treated with sulfadiazine (sdz). it provides the opportunity to analyze the conversion of...
