Special Issue Information

Dear Colleagues,

Infectious and parasitic diseases of domestic and wild animals are a major concern for the economic sustainability of the livestock industry and wildlife conservation and pose a serious threat to public health. Among all of them, toxoplasmosis is particularly relevant. It is a zoonotic disease caused by Toxoplasma gondii, an obligate intracellular coccidian belonging to the phylum Apicomplexa. Besides being a parasite of major concern for animal health, T. gondii can lead to abortions in women and severe neuromuscular complications or even death in immunocompromised people and newborns and is the most widespread zoonotic parasite in humans.

In this Special Issue, we aim to provide the opportunity to publish original research or review papers that improve our understanding of toxoplasmosis in domestic and wild animals: geographical spread and host range, risk factors, molecular characterization, the influence of different involved agents, development and validation of new diagnostic tools, etc., that aid in addressing the particular challenges in the surveillance, monitoring, control, and ecopathological characterization of this disease.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 CHF (Swiss Francs).

Toxoplasmosis is mainly transmitted to human beings through the consumption of contaminated food, and several outbreaks caused by infected meat consumption have been reported in Brazil. We performed a systematic literature review on the prevalence and risk factors for toxoplasmosis in slaughtered animals and performed a meta-analysis of its prevalence for different species and regions. Furthermore, we also discussed the infectivity of seropositive animals, risk factors, and preventive strategies. In the meta-analysis, the overall prevalence estimates for poultry, ostrich, goats, swine, equids, sheep, and bovines were 42.4, 40.4, 23.0, 19.9, 19.1, 17.3, and 16.2%, respectively. Regarding the Brazilian regions, the highest prevalence values were detected for bovines and equids in the South (32.3 and 34.4%, respectively) and swine, goats, sheep, and poultry in the Northeast (29.3, 23.0, 22.9, and 69.8%%, respectively). High proportions of Toxoplasma gondii viability in bioassay conducted on seropositive animals were seen for sheep (34/40 = 85%) and swine (12/15 = 80%). Toxoplasma gondii infections are widespread on Brazilian farms, and the summarized data allow the establishment of high-priority areas and/or species for the adoption of preventive strategies to control this parasite at different levels of the food chain.
