Special Issue Information

Dear Colleagues,

Toxoplasma gondii is an apicomplexan parasite found throughout the world and the etiologic agent of toxoplasmosis. This parasite is of major human clinical importance since it causes serious complications from the fetus to adulthood, namely when primary infection or reactivation occurs in pregnant women and immunocompromised individuals. Its pathology varies according to several factors, including the genotype and immunological status of the host, parasite genotype, and virulence factors. A lack of knowledge exists concerning the unique host cell-mediated mechanisms and parasite molecular targets involved in parasite persistence and the induction of pathology. There still no human vaccines available and the current chemotherapy lacks efficacy against tissue cysts, with safety concerns due to the induction of adverse side effects associated with poor compliance within patients.

This Special Issue of Microorganisms aims to present a collection of articles that highlight research in the field of toxoplasmosis. Manuscripts covering all aspects of research relating to toxoplasmosis are welcome, including work from applied areas, such as novel drug targets and respective promising compounds, vaccines avoiding parasite invasion, proliferation and persistence and, thus, pathogenesis.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Toxoplasmosis is a parasitic disease caused by the globally distributed protozoan parasite Toxoplasma gondii, which infects around one-third of the world population. This disease may result in serious complications for fetuses, newborns, and immunocompromised individuals. Current treatment options are old, limited, and possess toxic side effects. Long treatment durations are required since the current therapeutic system lacks efficiency against T. gondii tissue cysts, promoting the establishment of latent infection. This review highlights the most promising drug targets involved in anti-T. gondii drug discovery, including the mitochondrial electron transport chain, microneme secretion pathway, type II fatty acid synthesis, DNA synthesis and replication and, DNA expression as well as others. A description of some of the most promising compounds demonstrating antiparasitic activity, developed over the last decade through drug discovery and drug repurposing, is provided as a means of giving new perspectives for future research in this field.
