Toxoplasma gondii is a neurotropic apicomplexan protozoan estimated to affect approximately 30% of the global population. In this review, we aimed to examine scientific evidence on the potential role of T. gondii infection in the development of autism spectrum disorder (ASD), a heterogeneous neurodevelopmental disorder.

In this study, we investigated the effect of ivermectin (IVE) on the expression of transcription factors GATA-binding protein 3 (GATA-3), T-bet, and ROR-γt as well as wound healing Leishmania infection. Leishmania promastigotes were subcutaneously inoculated into the tail base of BALB/c mice ( = 10 per group) who later received phosphate-buffered saline (PBS), IVE, Glucantime, or a combination of IVE and Glucantime as soon as wounds developed, approximately three weeks' postinfection.

However, no effective vaccine has been provided for this parasite, so this study was designed to evaluate the immunogenicity of a chimeric multi-epitope antigen as a potential toxoplasmosis vaccine candidate in a murine model. The multi-epitope vaccine candidate, designed with bioinformatics tools, MGS: a chimera of MIC13, GRA1, and SAG1 antigens, was expressed in BL21 and purified by immobilized metal affinity chromatography using a His Ni-NTA column.

Aims: The purpose of this study was to design a multi-epitope vaccine using several bioinformatics approaches against the antigens of .
Methods: Three proteins of , including ROP18, MIC4, and SAG1 were analyzed to predict the most dominant B- and T-cell epitopes.
() is a cosmopolitan protozoan parasite in humans and animals. It infects about 30 % of the human population worldwide and causes potentially fatal diseases in immunocompromised hosts and neonates. For this study, five English-language databases (ScienceDirect, ProQuest, Web of Science, PubMed, and Scopus) and the internet search engine Google Scholar were searched.

Identifying the antigens that trigger immune responses during infection is extremely important for the development of vaccines against infections. Several studies conducted in recent decades have described the specific traits of the protective antigens found in and their role in immunizing different animal hosts.

Body fluids such as milk are used to diagnose many parasitic diseases, including toxoplasmosis. Therefore, this study aimed to investigate the role of milk as a non-invasive and alternative sample for serum in the diagnosis of animal toxoplasmosis.
