Previously, our laboratory showed that Holstein cattle experimentally infected with Neospora caninum develop parasite-specific CD4+ cytotoxic T lymphocytes (CTL) that lyse infected, autologous target cells through a perforin-granzyme pathway. To identify specific parasite antigens inducing bovine CTL and helper T-lymphocyte responses for vaccine development against bovine neosporosis, the tachy...

Besnoitia besnoiti infection in cattle is an important emerging protozoan disease in Europe causing economic losses and severe clinical signs, such as generalized dermatitis, orchitis, and vulvitis in affected animals. Neutrophil extracellular trap (NET) formation was recently demonstrated as an important effector mechanism of PMN acting against several invading pathogens. In the present study,...

Despite the enormous economic importance of Neospora caninum related veterinary diseases, the number of effective therapeutic agents is relatively small. Development of new therapeutic strategies to combat the economic impact of neosporosis remains an important scientific endeavor. This study demonstrates molecular, structural and phenotypic evidence that N. caninum calcium-dependent protein ki...

    Background & Aim: Toxoplasmosis is caused by a protozoan parasite called toxoplasma gondii. SAG1 is an antigen which only exists in tachyzoite stage. This antigen which has two glycoforms is a conformational antigen. The aim of this research is to study cloning of SAG1 gene in PTZ57R and transformation of recombinant plasmid in E.coli(TG1 & DH5a). Material & Method: Tachyzoites of T.gondii ...

 This study was aimed to detect anti-Toxoplasma gondii antibodies in cats infected with Rh strain of T. gondii by using an immunoblotting method. For this, cats were experimentally infected using tachyzoites harvested from Vero cell cultures. Tachyzoites were then lysed and transferred to polyacrylamide gels followed by blotting to PVDF membranes. An immunoblotting was performed using these mem...
