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

The parasite Cystoisospora suis causes diarrhea especially in newborn piglets and spreads quickly across farms. Pig farmers in Europe preventively use toltrazuril to control parasite development. In contrast to congeneric parasites in chicken, no resistance to toltrazuril was described in pig parasites until recently. Researchers of Vetmeduni Vienna now confirmed for the first time that toltrazuril is ineffective against a Dutch isolate. Even though the antiparasitic resistance is developing slowly, monitoring of resistance should be intensified due to the lack of alternative treatment options, and increased hygiene measures should be taken to prevent pathogen spread.
