Special Issue Information
Dear Colleagues,
Toxoplasma gondii, found on every continent, is one of the world's most ubiquitous pathogens. This intracellular protozoan belongs to the subclass Coccidia and phylum Apicomplexa. Toxoplasma gondii is theoretically capable of infecting all homeotherms (mammals and birds) and is responsible for the zoonotic disease toxoplasmosis. In humans, the primary routes of infection are the consumption of undercooked meat containing parasite cysts of plants or water contaminated with oocysts released by felines into the environment, and congenital transmission. Infection, although generally asymptomatic in immunocompetent individuals, can cause severe ocular, cerebral and even multivisceral damage in immunocompromised patients, fetuses, and newborns. A growing number of studies suggest that the parasite's genetic diversity plays a role in its pathogenicity, and it appears that tropical zones with low levels of human settlement are more prone to severe forms. In animals, toxoplasmosis has significant veterinary and economic implications, particularly in livestock and companion animals. Given the large reservoir of this parasite, i.e., animals (both definitive and intermediate hosts), human medicine cannot perform without veterinary medicine. The scientific progress needed to control or better understand this zoonosis calls for a multidisciplinary approach.
This Special Issue aims to bring together recent advances in the epidemiology, diagnostics, transmission dynamics, host–pathogen interactions, public health implications, and control strategies for T. gondii. We welcome original research articles, reviews, and case studies that address both human and animal aspects of the disease, with an emphasis on One Health perspectives and interdisciplinary approaches to prevention and surveillance. By highlighting recent developments and challenges, this Special Issue seeks to inform clinical practice, veterinary medicine, and public health policy.

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 250 words) can be sent to the Editorial Office for assessment.
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. Pathogens 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 2200 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.
