Article Synopsis
  • The study confirms that the trematode parasite Derogenes lacustris can be transmitted from native fish (Galaxias maculatus) to introduced fish (Oncorhynchus mykiss) in Patagonia.
  • The transmission rate observed was 19%, with significant growth in the parasite's body length and an increase in egg production two weeks post-infection.
  • This research is the first to provide experimental evidence of post-cyclic transmission in trematodes, indicating that it may help D. lacustris expand its host and geographical range in Argentinean Patagonia.
