  Toxoplasma gondii is an intracellular parasite that causes a variety of clinical manifestations. Acute and chronic phases of toxoplasmosis are considered as the presence of actively proliferating tachyzoites in the nucleated cells of mammalian hosts such as humans, and spread through blood to other parts of the body, which subsequently forms tissue cysts. The present study was aimed to evaluate the diagnostic value of nested real-time polymerase chain reaction (PCR) for the acute and chronic phases of toxoplasmosis in the laboratory mice using compared to conventional real-time PCR. To induce acute toxoplasmosis, 103 tachyzoites of Toxoplasma gondii RH strain were intraperitoneally inoculated to 25 BALB/c mice. In order to induce chronic toxoplasmosis, the mice were subcutaneously infected by the parasite and then treated with sulfadiazine from day one to day 14 post-injectio.. View More»
