The Efficacy of Albendazole, Fenbendazole and Metronidazole for Treatment of Canine Giardia

Current treatments for canine Giardia infections include albendazole, fenbendazole and metronidazole in the most cases. To compare efficacy of these antimicrobial drugs for treating naturally infected giardiasis in dogs, we used the zinc sulfate concentration technique(ZSCT) to figure out naturally infected with Giardia. In this study, feces were collected from 150 asymptomatic dogs at a kennel, 28 asymptomatic Giardia infected dogs were used by the allocated four group to receive albendazole(group A, 25 mg/kg, PO, bid, 7 days), fenbendazole(group F, 50 mg/kg, PO, sid, 7 days), metronidazole (group M, 50 mg/kg, PO, sid, 7 days), nontreated control(group NC) respectively. Fecal samples from each dog were examined for Giardia cysts within 3 days of the last treatment. Giardia cysts were not detected in the feces of any dog in group F. Cysts were detected in the feces 1 of 7 dogs in group A or in the feces 2 of 7 dogs in group M. In the group NC, cysts were detected in the feces of 7 of 7 dogs. Finally, there was significant difference for efficacy between antimicrobial drugs against Giardia in dogs. Fenbendazo1e is the most efficacy to have giardiacidal activity.
