The International Congress on Toxoplasmosis is an integral event for our field as it unites a global community of students, young researchers and established leaders. In line with tradition, this conference will cover all aspects of Toxoplasma research, ranging from molecular biology to clinical disease and epidemiology—and thus we hope will spark interdisciplinary interactions. We expect up to 250 participants from around the world, many of whom will have the opportunity to present their latest work in short talks, turbo talks or posters.Apart from scientific presentations, we look forward to many stimulating discussions and networking opportunities. As in previous years, ToxoXVII will be preceded by two workshops from special interest groups – those keeping an eye on the oocyst stage (3rd Environmental Toxoplasmosis Workshop), and the big data scientists participating in and running the ToxoDB workshop (who are an invaluable asset to our community!).
