Cytotoxicity and Antiparasitic Effects of Toltrazuril Against Enteromyxum leei in Olive Flounders: In Vitro and In Vivo Analyses. [PDF]

J Fish Dis
ABSTRACT The parasite Enteromyxum leei causes serious emaciation disease in marine fish species. Toltrazuril exhibits antiparasitic effects; however, the simultaneous impacts of toltrazuril on parasites and hosts are unclear. Here, we evaluate the cytotoxicity of three commercial toltrazuril products (A, B and C) and the treatment efficacy against E ...

Unclear host taxonomy hinders parasite studies: An up-to-date checklist of the protozoan and metazoan parasites of Phoxinus minnows (Teleostei: Leuciscidae). [PDF]

J Fish Biol
Abstract Phoxinus minnows are small freshwater fish found throughout Eurasia. The taxonomy of this genus is still under investigation, and new species are regularly described. They are frequently introduced outside their native range due to their use as live bait for angling, and such fish introductions can have diverse impacts on the recipient areas ...
