background blood transfusion is one of the many ways, through which toxoplasma gondii (t. gondii), a protozoan parasite, can be transmitted to humans. objectives this cross sectional study aimed to evaluate the seroprevalence of toxoplasma infection and related epidemiological features among healthy blood donors. materials and methods a total of 375 blood samples from donors were tested for spe...

Azithromycin was shown to specifically inhibit the protein synthesis of Toxoplasma gondii in experimental systems by using free tachyzoites and T. gondii-infected mouse macrophages. RNA synthesis of the parasite was not affected by azithromycin. Inhibition of protein synthesis was also proportional to the relative anti-Toxoplasma activity of three macrolides.

Serological screening and evaluation of exposure factors for Toxoplasma gondii transmission were conducted in 2126 pregnant women from southern Brazil. Specific antibodies against Toxoplasma gondii were presented by 74.5% (n=1583) of the pregnant women evaluated. Contact with soil was found to be the major factor for infection.

UNLABELLED Toxoplasma gondii ME49 is an obligatory intracellular apicomplexa parasite that causes toxoplasmosis in humans, domesticated and wild animals. Waterborne outbreaks of acute toxoplasmosis worldwide reinforce the transmission of Toxoplasma gondii ME49 to humans through contaminated water and may have a greater epidemiological impact than previously believed. In the quest for drug and v...

Background Beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. Blood transfusion can transmit Cytomegalovirus (CMV) and Toxoplasma gondii. The aim of this study was serological evaluation of these two infectious agents in thalassemia patients. Materials and Methods In a cross-sectional study, the enzymelinked immunosorbent assay (ELISA) testing was pe...

BACKGROUND Toxoplasmosis is an infectious disease caused by the parasitic protozoan Toxoplasma gondii. It is endemic worldwide and, depending on the geographic location, 15 to 85% of the human population are asymptomatically infected. Routine diagnosis is based on serology. The parasite has emerged as a major opportunistic pathogen for immunocompromised patients, in whom it can cause life-threa...

Toxoplasmosis and leishmaniasis are two worldwide zoonoses caused by the protozoan parasites Toxoplasma gondii and Leishmania spp., respectively. This report describes the clinical and laboratorial findings of a co-infection with both parasites in a 4-year-old female dog suspected of ehrlichiosis that presented anemia, thrombocytopenia, hypoalbuminemia, hyperglobulinemia, tachyzoite-like struct...

BACKGROUND Toxoplasmosis is a parasitic disease caused by the protozoan Toxoplasma gondii. This parasite infects most of warm-blooded animals, including birds. Turkeys are one of these animals which might be infected by this parasite. Little is known about the prevalence of T. gondii in turkeys in Iran. OBJECTIVES The current study aimed to evaluate the rate of Toxoplasma infection in turkeys...

INTRODUCTION Infection with the ubiquitous parasite Toxoplasma gondii is a threat for immunocompromised patients and pregnant women and effective immune-prophylaxis is still lacking. METHODS Here we tested a mixture of recombinant T. gondii antigens expressed in different developmental stages, i.e., SAG1, MAG1 and GRA7 (SMG), and a lysate derived from T. gondii tachyzoites (TLA) for prophylac...

Toxoplasmosis, caused by the protozoan Toxoplasma gondii, is medically important and distributed worldwide. Currently available medications are limited in terms of efficacy and side effects. We synthesized novel, nonacetal, hydrolytically stable derivatives of artemisinin and showed that they inhibit the replication of Toxoplasma gondii in cell culture.
