To determine the seroprevalence of anti-Neospora caninum and anti-Toxoplasma gondii antibodies indogs in Iran and to investigate related risk factors to the infection, a study was conducted in Chaharmahal vaBakhtiari, Isfahan and Khoozestan provinces, locate in west central parts of Iran. For this, 548 serum samples were collected from dogs during an 18 month period from July 2007 to February 2...

The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii rhoptry antigens, ROP2 and ROP4, with respect to toxoplasmosis detection and infection phase distinction in laboratory mouce by determining specific serum IgM and IgG antibodies with the use of indirect ELISA technique. The mice antibody response to ROP antigens was significantly higher in the...

b ackground: toxoplasmosis is a serious disease in immunocompromised patients and pregnant women. differentiation of acute and chronic infection is a major challenge in serodiagnosis of the disease. since the aim of this study was to assess the diagnostic utility of recombinant sag1 (rec- sag1) for the detection of toxoplasma -specific igm antibodies in human sera, by an enzyme-linked immunosor...

Toxoplasmosis is a major public health problem and the development of a human vaccine is of high priority. Efficient vaccination against Toxoplasma gondii requires both a mucosal and systemic Th1 immune response. Moreover, dendritic cells play a critical role in orchestrating the innate immune functions and driving specific adaptive immunity to T. gondii. In this study, we explore an original v...

An ELISA was established to measure bovine IgG directed against the recombinant antigenic determinant of Nc-p43, a major surface antigen of Neospora caninum. In a previous study, two thirds of the C-terminal of the molecule was expressed as a 6 x His tagged protein (Ncp43P) for ELISA using 2/3 of the N-terminal of SAG1 from Toxoplasma gondii as a control (TgSAG1A). Among 852 cattle sera collect...

To improve serodiagnostic methods for the diagnosis of acute toxoplasmosis during pregnancy, a new test system has been developed and evaluated based on the use of recombinant antigens. Five recombinant Toxoplasma gondii antigens (ROP1, MAG1, SAG1, GRA7, and GRA8) were cloned in Escherichia coli, purified, and applied directly onto nitrocellulose membranes in a line assay (recomLine Toxoplasma)...
