Acidocalcisomes in Toxoplasma gondii tachyzoites.
Toxoplasma gondii tachyzoites were loaded with the fluorescent indicator fura 2 to investigate the transport mechanisms involved in maintaining their intracellular Ca2+ homoeostasis. The mitochondrial ATPase inhibitor oligomycin and the endoplasmic-reticulum Ca(2+)-ATPase inhibitor thapsigargin increased the intracellular Ca2+ concentration ([Ca2+]i), thus indicating the requirement for ATP and...
متن کاملIdentification of compounds that suppress Toxoplasma gondii tachyzoites and bradyzoites
Drug treatment for toxoplasmosis is problematic, because current drugs cannot eradicate latent infection with Toxoplasma gondii and can cause bone marrow toxicity. Because latent infection remains after treatment, relapse of infection is a problem in both infections in immunocompromised patients and in congenitally infected patients. To identify lead compounds for novel drugs against Toxoplasma...
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 کامل[Cryopreservation of Toxoplasma gondii tachyzoites and tissue cysts].
Toxoplasma gondii tachyzoites and tissue cysts are largely used for developing diagnostic assays, vaccines and in drug research as well as biochemical and molecular structure studies. Continuous passaging of tachyzoites or tissue cysts in animal models encounter ethical and economical problems and it is a time consuming procedure. Cryopreservation of tachyzoites and tissue cysts and revitalizat...
متن کاملTriazine Inhibits Toxoplasma gondii tachyzoites in vitro and in vivo.
The triazine WR99210 [4,6-diamino-1,2-dihydro-2,2-dimethyl-1-(2,4,5-trichlorophenoxypropyloxy)-1,3,5 triazine] inhibits Toxoplasma gondii in vitro at nanomolar levels (P < 0.05). The 50% inhibitory concentration (IC(50)) was approximately 50 nM. It is a potent inhibitor in vitro and is also effective in vivo. Administration of WR99210 parenterally (i.e., intraperitoneally) reduced the mean numb...
