background: toxoplasmosis is one of the most common parasitic infections of humans and other mammals. this study was aimed to understand the mechanism of action of veterinary medicine-sulfachloropyrazine (spz, 99.97%) against toxoplasma gondii . methods: t. gondii tachyzoites were soaked in pbs (as a control) or spz (250 mg/ml) for 2 h at 37 °c. after being processed, any ultrastructural change...

background: psychiatric patients have an increased risk of some infections like toxoplasmosis. investigations on toxoplasma gondii infection among psychiatric patients have been limited in mashhad, northeast of iran. in this case-control study, prevalence of t. gondii was investigated by serological method. methods: this case-control study was performed among psychiatric patients admitted to av...

introduction toxoplasma gondii is one of the most important pathogen that has adverse effect on reproductive function. evidence acquisition recent studies revealed that infection with t. gondii not only affect female reproduction, also cause male reproductive impairment. in clinical studies, high prevalence of toxoplasmosis in sterile men has been reported. in animal models, toxoplasmosis is as...

background and objectives: toxoplasmosis has become one of the more frequent opportunistic infections and the most common cause of focal brain lesions complicating the course of aids. however, there is a little information about the frequency of the toxoplasmosis in various regions of iran. at the present study, we evaluated the prevalence of toxoplasmosis in patients with aids in mashhasd (nor...

We describe a renal transplant patient with a primary Toxoplasma gondii infection presenting as pneumonitis, with subsequent chorioretinitis and encephalitis. The diagnostic challenges of T. gondii infection in immunocompromised patients are discussed.

Field studies were conducted on 47 swine farms in Illinois during 1992 and 1993 to identify sources and reservoirs of Toxoplasma gondii infection. Blood samples were obtained from swine and from trapped wildlife. Serum antibodies to T. gondii were determined using the modified agglutination test, incorporating mercaptoethanol. Antibodies to T. gondii (titer > or = 25) were found in 97 of 4,252 ...

Toxoplasma gondii (T. gondii) is a protozoan parasite, infecting most of the warm-blooded animals, including humans who are the intermediate host. Members of cat family Felidae are the definitive hosts. T. gondii infection is acquired by humans by accidental ingestion of oocysts in water, food or soil contaminated with cat feces, or by eating raw or undercooked meat containing cysts. Studies co...

toxoplasmosis is a common and widespread infection in humans and many other species of warm–blooded animals. toxoplasma gondii-derived heat shock protein 70 (hsp70) may play an important role in the virulence of toxoplasma gondii (t. gondii). in the present study, t. gondii hsp70 was amplified by polymerase chain reaction (pcr) from the dna of the t. gondiitachyzoite rh strain through the use o...

Human platelets, in the absence of antibody, are cytotoxic to tachyzoites of Toxoplasma gondii as determined by vital staining, transmission electron microscopy, and the failure of Toxoplasma to survive and replicate in mice after in vitro interaction of the organisms with platelets . Platelet to T. gondii ratios as low as 1 :3 were toxic to the organisms with direct cell-cell contact essential...

Background: Toxoplasma gondii is an intracellular protozoan with worldwide distribution capable of infecting all endothermic vertebrates. Latent toxoplasmosis in man and animals is considered as clinically asymptomatic. The aim of this Study is evaluation of the effects of Toxoplasma gondii on Biochemical Parameters of Reproductive Function in Male Rats. Materials and Methods: A total of 56 mal...
