Efficacy of a low-dose praziquantel and fenbendazole protocol in the treatment of asymptomatic schistosomiasis in dogs.

Background: Established treatment protocols for schistosomiasis (Heterobilharzia americana) in dogs are expensive. Anecdotal reports suggest that lower doses of praziquantel, combined with fenbendazole, may eliminate asymptomatic infections.

Objectives: Evaluate the efficacy of a low-dose praziquantel and fenbendazole protocol to manage asymptomatic schistosomiasis in dogs and compare fecal saline sedimentation (FSS) and fecal PCR (FPCR) for therapeutic monitoring.
