Toxoplasma gondii infects almost all warm-blooded animals and negatively affects the health of a wide range of these animals, including humans. Protein phosphatase 2C (PP2C) is a T. gondii protein secreted by rhoptry organelles during host cell invasion. However, very little is known about whether
The purpose of this study was to implement a fluorometric method for enhancing the detection sensitivity of Toxoplasma gondii in biological fluids. To address this challenge, we designed and produced a recombinant immunoconjugate tool based on a single-chain antibody fragment anti-T.
Enzyme-linked immunosorbent assay (ELISA) for toxoplasmosis was evaluated in serum samples presenting defined toxoplasmosis serological patterns, as determined by results in immunoglobulin (Ig)G and IgM immunofluorescence (IgG-IF, IgM-IF), hemagglutination, and complement fixation tests. ELISA was
We report a case of watery diarrhea due to duodenal toxoplasmosis in a patient with the acquired immunodeficiency syndrome. Treatment with pyrimethamine, clindamycin, and folinic acid decreased the diarrhea as well as the duodenal toxoplasma cyst load. Hepatic toxoplasmosis was also present,
This article describes a microfluidic LIF immunosensor for the quantitative determination of anti-Toxoplasma gondii IgG (anti-T. gondii) specific antibodies. The serological detection of these antibodies plays a crucial role in the clinical diagnosis of toxoplasmosis. Zinc oxide nanoparticles
The peripheral blood lymphocytic activities of acid phosphatase (AP) and acid nonspecific esterase (ANE) (alpha-naphthylacetate esterase) were determined in 45 patients with chronic acquired toxoplasmosis on an exacerbation. There was a considerable increase in the activity of AP in the white blood
One hundred and fifteen sera from nineteen patients undergoing bone marrow transplant and four recipients of kidney transplant who showed serological or clinical reactivation of chronic toxoplasmosis were tested for Toxoplasma gondii circulating antigen (TCA) by enzyme-linked immunosorbent assay
The purpose of this study was to design a novel in vitro tool by using recombinant protein technology to detect specific antibody responses against Toxoplasma gondii in a simple, rapid and highly sensitive reagent. The surface T. gondii SAG1 protein is an important immunodominant target, which
Toxoplasma gondii is a human protozoan parasite that belongs to the phylum of Apicomplexa and causes toxoplasmosis. As the other members of this phylum, T. gondii obligatory multiplies within a host cell by a peculiar type of mitosis that leads to daughter cell assembly within a mother cell.
Toxoplasma antigen and Toxoplasma immune complex were shown to induce increased production and release of acid hydrolases from macrophage cell line P388D in a concentration-dependent manner. Antigen concentrations of 10-50 microg/ml gave a 2-4-fold increase in the activities of acid proteinase, acid
BACKGROUND
Toxoplasma gondii is an obligate intracellular zoonotic parasite of the phylum Apicomplexa which infects a wide range of warm-blooded animals, including humans. In this study in-vivo induced antigens of this parasite was investigated using in-vivo induced antigen technology (IVIAT) and
RNA-sequencing was used to detect transcriptional changes in six tissues of cats, seven days after T. gondii infection. A total of 737 genes were differentially expressed (DEGs), of which 410 were up-regulated and 327 were down-regulated. The liver exhibited 151 DEGs, lung (149 DEGs), small
A mouse monoclonal antibody (HC1/1) specific for a differentiation marker of human monocytes and granulocytes has been generated by using as immunogen the monocytic cell line U937 differentiated with phorbol esters. This differentiation antigen has been characterized as the p150/95 member of the
Toxoplasma gondii infection in pregnant women may result in abortion and foetal abnormalities, and may be life-threatening in immunocompromised hosts. To identify the potential infection markers of this disease, 2-DE and Western blot methods were employed to study the parasite circulating antigens
