Drug resistance in an intestinal parasite of piglets confirmed for the first time

(University of Veterinary Medicine -- Vienna) Cystoisospora suis causes diarrhea especially in newborn piglets and spreads quickly across farms. European farmers preventively use toltrazuril to control parasite development. In contrast to congeneric chicken parasites, no resistance to toltrazuril was described in pig parasites until recently. Researchers of Vetmeduni Vienna now confirmed ineffectivness of toltrazuril against a Dutch isolate. Although the resistance develops slowly, monitoring should be intensified due to the lack of alternative treatment options and hygiene measures should be increased.
