Symposium on Triploidy in Parasitic Worms April 14-17, 2026 Eawag, Dübendorf, 8600, Switzerland The Symposium on Triploidy in Parasitic Worms is a meeting of researchers from various fields of helminthology. The main idea of the Symposium is to discuss how triploidy (or polyploidy more generally) can affect the ecology and evolution of parasitic worms and, consequently, host-parasite dynamics. During the symposium, we will have talks on such topics as (but not limited to): Host-Parasite Interaction Drug Resistance Cytogenetics and genomics Evolution of reproductive systems Ecology and Distribution of Triploidy The preliminary schedule of the Symposium is on the website: https://www.pathogenevolution.ch/symposium-on-triploidy While most presenters are invited speakers, the Symposium is open to anyone interested in parasitic worms and polyploidy. You are welcome to attend any talk or present results of your own study if you think that your work is connected to any of the topics mentioned before.
