background : toxoplasma gondii is an obligate intracellular protozoan parasite, capable of infecting all species of mammals including man. congenital toxoplasmosis is more important during pregnancy for the first time. in this study we expressed and purified p43 toxoplasma gondii tachyzoite and bradyzoite specific surface antigen. methods : the recombinant pgemex-1 contained toxoplasma p43 codi...
Sheep are important in the epidemiology of Toxoplasma gondii infection but little is known of ovine toxoplasmosis in Brazil. Antibodies to T. gondii were assayed in sera of 495 sheep from 36 counties of São Paulo State, Brazil, using the modified agglutination test (MAT titer > or =1:25) and found in 120 (24.2%). Samples of brain, heart, and diaphragm of 82 seropositive sheep were pooled, diges...
It has been 100 years since Toxoplasma gondii was initially described in Tunis by Nicolle and Manceaux (1908) in the tissues of the gundi (Ctenodoactylus gundi) and in Brazil by Splendore (1908) in the tissues of a rabbit. Toxoplasma gondii is a ubiquitous, Apicomplexan parasite of warm-blooded animals that can cause several clinical syndromes including encephalitis, chorioretinitis, congenital...
Cerebral toxoplasmosis is one of the frequent opportunistic infections central nervous system Human Immunodeficiency Virus (HIV) patients in presence Toxoplasma Gondii infection. In Indonesia, incidence HIV with cerebral 45%. This study was done to determine demographic, clinical, and laboratory characteristics at Haji Adam Malik Hospital, Medan, based on medical record data 2022. The total sam...
Toxoplasma gondii pathogen is a threat to human health that results in economic burden. Unfortunately, there are very few high-efficiency and low-toxicity drugs for toxoplasmosis in the clinic. (+)-Usnic acid derived from lichen species has been reported to have anti-inflammatory, antibacterial, anti-parasitology, and even anti-cancer activities. In associated with the published article "Effect...
Infection with Toxoplasma gondii is often asymptomatic and, when acquired during pregnancy, may lead to connatal toxoplasmosis in the offspring. The newly introduced Vitros anti-Toxoplasma immunoglobulin G (IgG) and IgM assays, designed for the Vitros ECiQ immunodiagnostic system, a fully automated system based on chemiluminescence, were evaluated as a screening method for the serological detec...
Infection with the protozoan parasite Toxoplasma gondii is characterized by asymptomatic latent infection in the central nervous system and skeletal muscle tissue in the majority of immunocompentent individuals. Life-threatening reactivation of the infection in immunocompromized patients originates from rupture of Toxoplasma cysts in the brain. While major progress has been made in our understa...
A total of 254 humans and 489 domestic animals living on farms in the Lublin province (eastern Poland) were examined for the presence of antibodies against Toxoplasma gondii using, respectively, the ELFA and direct agglutination tests. In parallel, 182 samples of potable water, mostly from shallow household wells, were taken on farms and examined for the presence of T. gondii by microscopy and ...
Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the serop...
The prevalence of viable Toxoplasma gondii was determined in 6,282 samples (2,094 each of beef, chicken, and pork) obtained from 698 retail meat stores from 28 major geographic areas of the United States. Each sample consisted of a minimum of 1 kg of meat purchased from the retail meat case. To detect viable T. gondii, meat samples were fed to T. gondii-free cats and feces of cats were examined...
