Identification 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 کاملAcidocalcisomes 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 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 کاملThe development and biology of bradyzoites of Toxoplasma gondii.
Toxoplasma gondii is a protozoan parasite of mammals and birds that is an important human pathogen. Infection with this Apicomplexan parasite results in its dissemination throughout its host via the tachyzoite life-stage. After dissemination these tachyzoites differentiate into bradyzoites within cysts that remain latent. These bradyzoites can transform back into tachyzoites and in immunosupres...
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...
